I'm pretty sure those pictures aren't real. They aren't on the website. I'm guessing someone just photo shopped a 10mm on the chamber.

Also, if they release a 5.25" model, as would be expected at some point, I sure hope they would have the good sense not to have that stupid slide cut on top of the slide. I want mass out front to limit muzzle flip. Additionally, lets not taper the slide off at the end. Give me a full length rail too. I don't care what it weighs. I want a meaty 10mm, not some chopped up nonsense.

Slide cuts are often found to reduce muzzle flip. Frame weight helps with flip. Slides are set in motion by the recoil of the round firing, and the vast majority of flip on semi-autos happens when the slide slams into the frame at the rear of travel. Watch slo-motion video of any semi-auto pistol being shot and you can see this. (Recoil spring weights play into this, too). The frame is static, the slide moves. More weight on the frame tamps recoil. More weight on the slide means more weight slamming into the frame at the end of the recoil stroke. And more weight slamming forward on the return to battery.

Slide cuts aren't popular on speed-shooting competition guns because competitors are worried about carry weight!

So, how come a 30S flips more under recoil compared to a 30? Its pretty noticable to me and the only difference is slide weight, AFAIK
 
I have no idea, and perceptions of flip aren't always the same thing as actual flip/movement. Spring setup and small variations in grip can also influence things quite a bit.

I think you point here plays in. I mean the Brigadier slide variant of the Beretta 92 was designed to help mitigate muzzle flip I believe. Am I wrong on that? Same pressure/force moving more slide mass would indicate a bit slower slide movement. Perhaps the point is moot unless recoil spring weights are considered. Or rather, maybe it's a confusion on my part about what impacts the recoil impulse. More mass may indicate less recoil of the complete gun, but as you say, more top heavy mass may create more muzzle flip. Two different things.

I see your point though that more weight moving around could batter the frame more. However, what happen when a heavier recoil spring is used? Perhaps nothing. I recall a thread where either Sam1911 or 1911tunner stated that in aquality 191, the recoil spring does not slow the slide movement enough to have any impact on frame battery, and that it's only purpose was to return the slide to battery. He took a video of himself shooting the gun with o recoil spring inside the gun at all. I believe he did it quite a bit and detected no ill effects. However the specifics elude me, and a 45 acp is not a 10mm.

Perceived recoil and muzzle flip are fuzzy areas. So many shooter specific traits play in. Measurable differences however may be exactly as you say.

I'm going to give that article a read tonight. Thanks for posting it.
 
It's an interesting and multi-faceted topic, to be sure. I think you'll enjoy the series of articles.
 
First, my brother had the front sight on his Springfield 1911 fly off. My brother sent it in, they took care of it. Good customer service, no complaints. Then I had the gas system shoot loose on my M1A and exhibit radical amounts of vertical stringing, esp when using a tight brace sling. I sent it in. They offered to return it to factory spec for free or install a unitized gas system for just the price of the part. I have them install the unitized gas system. Good service, good turn around, very excited to have my M1A back. Get six rounds into sighting it in and the bolt roller falls off. That's when I find out about Springfield Bolt Roller Impact and start scrutinizing them. Admittedly a little biased, but having parts rattle or fly off my rifles gets old fast.

I've shot a couple different XDs. They're decent. But I am an established Glock guy. I shoot them okay. More importantly I not only trust them. So shooting the XD for me was underwhelming. I remember when they called it a Glock killer. Umm, no.

THEN I hear about this political stunt they pulled with the IFMA thing...

Nope, I'm done. I think before I invest any more time in the M1A I have, I will get the M1 Garand (made by the real Springfield Armory, BTW) I just inherited from my grandpa up and running. And I certainly won't be supporting Springfield in the future. There are better options that allow you to better support the industry (and your rights) than giving money to Springfield Armory.
 
4.5 and 5.25 inch XDm models available. Doesn't appear any different than the other XDms. Didn't really expect it to though.
 
I had 3 XDm's in the past, the full size 9 and 40 as well as a compact 40. I shot them well and never had a problem with them, but given how many polymer 9's and 40's are out there they were easily replaced with guns I liked better. As much as I don't want to send money to SA, the 4.5 inch 10mm is exactly what I'm looking for in a woods gun. I had a 29 and still have a 20 but don't shoot them accurately due to the grip size. This is a need, as we vacation in places where bears and other wildlife are a concern, so I'll be at a LGS after work today ordering one.

Edit: It looks like it's not going to be in the stores for at least a couple of weeks. No rush to get to the LGS tonight.

I'll be honest. I looked into the XD 45 as an alternative to my Glock 21 gen 4 and absolutely didnt notice it being any smaller in the grip compared to the Glock. I know the specs say a bit thinner but my hands didnt notice.

You’re right about the XD45 grip, but the XDM’s have a different grip. It has 3 backstraps where the XD’s grip can not be changed.

Ah, that would make sense then. Do they have a longer grip to offset the thinner profile?
 
The 45 xD I once owned seemed to fit my smallish hand significantly better than my Glock 20 does, so there’s a pretty good chance I will give one of these a try at some point.

You can adjust the length of the grip with the 3 backstraps. I never tried the largest backstrap so I can’t say if it’s longer than the XD’s. I do know that the small and medium backstraps on the 9 and 40 worked for me.

Have you checked out the Bula/James River Armory M14? I sold my M1A Loaded (it was kinda meh), and am saving up for one of these:

Forged receiver, nice wood, great reviews and a steal at that price!
 
I guess I'm interested to know how these two guns stack up to the G20.

I load my180 gr 10mm ammo to around 1300 ft/sec and would like to know how the recoil impulse feels in both. Sure wish the local range had a G20 to try.

Also wished they'd used hotter ammo than Hydra-shocks to test it out. That stuff is not very warm.

I've read that all the slides are fully interchangeable between XDm models, would it be possible to put a 4.5 10mm slide on a compact XDm frame? This seems like it would make a very nice backcountry CC.
