so i bought one just before christmas, slapped a trijicon RMR on it, and started shooting. I try to shoot about 100 rounds every day and I passed the 5000 round mark this weekend (a little over 2 months since I first pulled the trigger) so I thought i would give the pistol and optic a little review. I've also been carrying this nearly every day in one of the hybrid kydex / leather IWB holsters.

All of those rounds have been reloads. The first 3000 were summit factory re-manufactured and the last 2000 were my own reloads. The latter are 124g plated over 4.05g of titegroup.

So... the grip:
I tried all of the interchangeable backstraps and eventually landed on the small one. However, it leaves quite a bit of gap at the top as i can't get the web of my hand up all the way due to the radius. so that's a bit suboptimal, but it puts the sites in a more natural spot for me so that's what i'm using.

I'm not sure why, but the CORE model I have has much more aggressive backstrap texture than the regular M&P9. I like it a lot better.

Trigger:
along about 1000 rounds into it, i was convinced I was not going to be able to pull the factory trigger straight back without the sights dipping. what an awful trigger. it was doubly worse because the only pistol i've carried for the past 10 years was a wilson combat 1911 with an awesome trigger, so i was really spoiled.

I dropped the apex trigger kit in there on 9mmEpiphany's recommendation and it made a world of difference. I'm thinking I may try some further enhancements too, as I would like a heavier pull with more spring reset. It's currently 5 lb and I think the heavier spring would take it to 6. In any event, it pulls straight back now and is much shorter. I still have to position my finger fairly low on the trigger though. that's probably just me.

Now my split times are .16 to .21, with .18-.19 being most common.

the sights:
it took me literally a couple thousand rounds to warm up to the RMR. for the first thousand, i could barely see the 8moa green dot. i always saw the bright white front sight dot first. eventually, i got used to it and now i see it really quick.

I like that the sights co-witness so i can use irons if i need to. however, the RMR does make it difficult as it has some sort of redish tint, and i have to clean it off quite a bit because it get cloudy from the powder residue.

The RMR is not nearly as bright as a battery powered red dot, but it is proportional with the ambient light just like an ACOG, so the dot isn't like staring into a spotlight at night, or washing out in the daytime. It is really nice in low light conditions. You can see the annoying red tint in the picture and the faint green dot. This pic was taken after dark in my basement lit by a couple 60w bulbs so not exactly bright light. The dot is crisp, but you will have to train your eye to see it. Don't expect to love it right out of the box.

The dot doesn't appear to be affected by polarized glass so it doesn't disappear when you turn the pistol sideways, but the combo of sunglasses and the red tint is pretty annoying. your target will be a little dark.

You do want to make sure you use loctite on the screws. mine came loose a few times before i decided to put loctite on it. no problems since.

the controls:
i'm a lefty, so the ambi slide stop/release lever is awesome. it's in exactly the right spot and isn't too hard or easy to operate. it doesn't stick out too far. i can push it up and down with my strong hand thumb any time. OTOH, i believe some of the failure to lock back on empty mag problems I had were due to my thumb putting a little downward pressure on this lever while i was shooting.

the mag release is also perfectly situated. and very easy to use. I seriously dislike the glock mag release, so this was a big advantage in my comparison.

the slide serrations:
i may change my method later, but for now i prefer not grabbing the slide at the rear so i don't accidentally put my dirty fingers on the RMR lens. Instead, I grab the slide in the center where it's slick. I think S&W made a pretty serious oversight here. The cuts in the back look nice, and would work great if you're not running an optic, but imho, for a pistol called C.O.R.E, they needed to put those slide cuts in a better spot.


thin slide:
most may not have noticed this but this model is scalloped on the sides and is quite a bit thinner than the regular M&P9. I have no idea why. I suppose it's a good bit lighter.

reliability:
anyone who's seen my posts in rifle country for the past 10 years knows I'm not a huge fan of cleaning guns. So it probably won't be a huge surprise to hear I've only cleaned the gun twice (and actually, I had someone else clean it). That was in the first 2000 rounds I think. It hasn't been cleaned in the past 3000 rounds. I've lubed it with SLIP2k EWL, but haven't reapplied lube in the past 2000 rounds.

The gun has been very reliable. Typical MEAL stuff... I've had several failures to lock back on empty slide, which I attribute to riding my thumb on the lever, or weak reman ammo.

I've also had maybe 3 times when a round ejected but the next round didn't feed properly. One of those was a mag failure where a round got jammed nose down deep in the mag so there was no spring pressure pushing up. The others were unknown cause.

Also had 4-5 rounds that didn't go bang, but after inspecting the ammo, it was obvious the primers weren't seated properly.

Shooting on steel, with two shooters alternating, I've put rounds through it fast enough that the slide is too hot to touch. It still runs fine.

accuracy:
it ain't a 1911. but it will do.


overall, i'd say i'm pretty happy with it. i'm not much of a pistol guy, but it is thin and comfortable to wear, even with the red dot, and conceals well enough. i'd buy one again.
 
I went into getting my M&P 9C factoring the Apex trigger kit into the cost. I have some minor issues with the M&P line, but that trigger...what are they thinking? It's awkward, it's gritty, and it's impossible to feel anything on it. That Apex makes a world of difference.

Is the slide stop easier to use than the regular M&P? The left hand (right side) slide stop for me is pretty spongy.

Regarding the sights: are there any battery-powered red dots that size that will last? If I get a RDS on a pistol, I want it to be like the aimpoints on my long guns - leave em on 24/7.

I like the CORE idea, and I am curious if other manufacturers will start producing pre-milled slides. The CORE model is $200 more than the stock model, but that factors in some other features as well. If you want your handgun custom milled, it's going to cost almost that to get it milled and refinished, get suppressor sights, (and more if you get more custom work done that you normally wouldn't, but "since it's there..."). In addition to that, you have to pay for shipping, and you have to wait that much longer to get your handgun.
 
Thanks for posting the review. I was very close to buying one of those last month, impulsively went with something else but I still want a CORE.

That was new specifically for the CORE model. I haven't seen it on any other models yet.

Trigger:
along about 1000 rounds into it, i was convinced I was not going to be able to pull the factory trigger straight back without the sights dipping. what an awful trigger. it was doubly worse because the only pistol i've carried for the past 10 years was a wilson combat 1911 with an awesome trigger, so i was really spoiled.

In any event, it pulls straight back now and is much shorter. I still have to position my finger fairly low on the trigger though. that's probably just me.

My CORE came with a "disappointing" trigger also. It was much different than the trigger in my other M&P Pro models. In my case, I solved the trigger issue by putting the CORE slide assembly on one of my other Pro frames. I've used Apex parts to improve the triggers on some of my regular M&P's, but my other Pro versions came with good triggers.

the sights:
it took me literally a couple thousand rounds to warm up to the RMR. for the first thousand, i could barely see the 8moa green dot. i always saw the bright white front sight dot first. eventually, i got used to it and now i see it really quick.

I also have the Trijicon RMR but with a 7 MOA amber dot. As you mentioned, it took some getting used to, but it works well for me now.

thin slide:
most may not have noticed this but this model is scalloped on the sides and is quite a bit thinner than the regular M&P9. I have no idea why. I suppose it's a good bit lighter.

The CORE model is part of the Pro series. At least in the 5" versions, the Pro series has always had the thinner slide, so that's not a new feature.

reliability:
The gun has been very reliable. Typical MEAL stuff... I've had several failures to lock back on empty slide, which I attribute to riding my thumb on the lever, or weak reman ammo.

I've also had maybe 3 times when a round ejected but the next round didn't feed properly.

The first 5" Pro series that I bought a number of years ago averaged 2 to 3 assorted mals per mag on the first trip to the range. Swapping different types of ammo and mags that I knew were good on my other M&P's didn't help. S&W customer service suggested that I send the gun back and they'd fix it. Being the stubborn and not-so-smart sort of person, I decided not to send it back but instead took a chance on buying a second one. My thinking was that as long as the second one was good, I could swap parts between the two and figure out what was wrong with the first. And of course, practicing malfunction correction is a good thing, right? :rolleyes:

In about 5000 rounds to date, the second one has had exactly 1 malfunction which was an ammo issue - a squib. My idea of figuring out what was wrong with the first by swapping parts with the second never panned out as swapping the parts one at a time didn't make any difference either way. The bad one still failed and the good one still ran. Over time though (a couple thousand rounds), the bad one has gotten "less bad" and instead of multiple mals per mag, I now get multiple mags per mal - sometimes 4 or 5 mags before a malfunction.
 
Thanks for the review. I was actually considering one of these and probably would have bought it sight unseen, figuring it was the same. Now I'll probably want to handle it in person before making the purchase, if I go that route...just to be sure it fits.

I'm going to have to pay closer attention to the slide stop next time I pick one up. It's something I don't really notice in a store, but that's the exact reason I don't use a Sig as a carry gun. My grip pushes the slide stop down every time.

there's a world of difference between my regular M&P 9 slide stop and the CORE above.

Regarding the sights: are there any battery-powered red dots that size that will last? If I get a RDS on a pistol, I want it to be like the aimpoints on my long guns - leave em on 24/7.

dunno. i'm pretty sure trijicon also makes a battery powered version. i don't know what the run time is. I have a burris fast fire II and it is great for competition type stuff, but it's definitely not a turn it on and leave it on sight.

and I am curious if other manufacturers will start producing pre-milled slides.
i think FN started it. I have had the FNP 45 tactical for years. not sure if they have a 9mm with pre milled slide though
 
In the CNC production run environment of manufacturing the additional machining of the slide is a minimal cost adder. It would be nice thou if the sighting system manufacture's would adopt a standard foot print but that's no going to happen. For now the adapter plates are the alternate in place of a standard.
 
Today I looked at this gun vs a PX4 Storm and a Glock 19. Anybody care to comment on how this gun compares to those? Any body have any comment on the PX4 or the G19? that they would care to share?
 
Taliv, I think the FN was a bit pricy and big. I'm thinking about pre-milled being as common as AR-15s with railed uppers.
 
Any body have any comment on the PX4 or the G19? that they would care to share?
Actually being a gun review thread about an M&P CORE I will make a small response to the G19. If you drop the slide on it, and it breaks on the nose where the guide rod is seated or on the rear corner where the rail groove is (bend and even crack like mine) Glock will not replace it. CS is not as good as S&W for repairs IMHO and FME.

Not comparing quality mind you, just CS and warranty. Hope that helps.

S&W customer service suggested that I send the gun back and they'd fix it. Being the stubborn and not-so-smart sort of person, I decided not to send it back but instead took a chance on buying a second one.
It's not too late, send it back. :what: :D
 
I imagine that will be inevitable. Not soon though, and always an upgrade/higher end feature not something present on the base models.

hangingrock, no argument here, but why wouldn't they also do it on the 4" or regular models?

i'm not expert on glocks, but i did happen to shoot the g19 a few times this past weekend as my daughter was trying out pistols. comparatively, the grips are nothing alike. the g19 feels blocky and short. the m&p is narrow and tall and very rounded, tapering at the bottom. the g19 is not ambi.

It would appear that S&W views the CORE series pistol as a limited/specialized application as opposed to an accepted standard.The optical/electro/ mechanical sight systems may not have reached a mature design/potential either or acceptance in the general shooting population. I believe thou we are in a transition period of sighting systems.
 
so 15000 rounds later i was blazing away one day last weekend hitting everything and the next i couldn't hit a thing. so i slowed down and still couldn't hit anything. then i grabbed the RMR and tried to twist it to see if it was loose... sure enough, it was. one of the screws was missing.

i ordered a couple extra from trijicon the next day. they arrived today and i discovered when i tried to stick a new screw in that it didn't just fall out as i supposed, but actually broke in half!

so i have half a screw stuck in my slide. i dropped it off at my gunsmith to see if he could get it out.

pretty annoying failure! but the iron sights still work
 
Thanks for posting the review. I was very close to buying one of those last month, impulsively went with something else but I still want a CORE.
Same thing happened to me...had convinced myself to buy either a regular 5" pro or a CORE, ended up with a CZ p-09.

Still want a C.O.R.E.
 
That's annoying! I had mine come loose around 900 rounds. Tightened them down, and came loose again after a few hundred more. added some blue loc-tite and it's been good. About 7K rounds through it now.

It's becoming my favorite pistol. I put an Apex aluminum trigger/FSS sear kit and RAM in mine. Very nice trigger.

Like you, it took me a while to get used to looking at the target rather than at the front sight. But once you do, it's very quick.

Thinking about having mine quadra-ported. But I mostly shoot low-to-mid plated reloads and I'm not sure how much benefit porting will be.

Shouldn't be an issue, assuming you told him you used Loc-Tite on the screw. Some heat (~500 F) and an EZ-out should do it. Been there done that.
 
accuracy:
it ain't a 1911. but it will do.

Good write up.

Could you put a number value on "good enough", perhaps best and average 25 yard groups?

The earlier M&P 9's were known for less than average accuracy. I didnt know if it had been fixed overall, or if the CORE guns dealt with it. I'm somewhat of an accuracy fan.
 
no, it still sucked. i literally could not hold the -0 zone on an idpa target at 25 yards from a rest. i replaced the barrel with one of the storm lake ones and it's much improved
 
Interesting. I was hopeful thay had improved the 9's. The info I've seen on the 40's and 45's is that they seem to shoot pretty well.

Thanks for the comment.
