Xdm 10 mm vs Glock 20

Ergonomics is entirely up to the individual shooter.

The XDM 10mm has little aftermarket support and is unproven. The Glock 20 is perhaps the most supported pistol platform in the world today by the aftermarket and is a proven and reliable design.

As far as ergonomics go, either you like Glocks or you don't. Ergonomics is very much a subjective thing. I don't care for the feel though I tried my best for about 3 years with a Glock 19 (Gen2). Excellent firearm, it just didn't feel to me like it was made for a human hand. A comparable HK VP9 or Walther PPQ is a better fit for me.

As far as reliability, I hear great things about the G20. I don't have one, but I understand it's a wonderful 10mm so long as you have the mitts to fit it. It tends to be the "go to" firearm if one's wanting a higher capacity 10mm. It's a shame Glocks don't fit me; I'd love to own a G40.

For the Springfield XD, I have an XDm 4.5 in .40S&W/.357Sig (Storm Lake barrel) and an XDm 5.25 in .45acp/.460Rowland (Roland conversion kit). I haven't had any problems with my XDms in both the original chambering or with the replacement barrel chambering. The .460 Rowland loaded to its potential is a monster.

I think you may want to get to a shop that has both and see what you think. Both have replaceable backstraps to better fit the user, so keep that in mind (G20 G4 and 5, IIRC).

I too was thinking about looking into the XDm 10mm as I love that cartridge, but I'm holding out for a PPQ or VP10... pipe dreams, you know?

I own an XDm-10 4.5" and put up a post on it here recently. I love the gun and would recommend it to anyone. It does have aftermarket support where it matters, although it doesn't really need much in that department IMO. If you want to make cosmetic changes I'm sure the Glock has more options. As long as it shoots (and it has done so flawlessly) none of that matters to me.
I'm sure an equivalent Glock would be just fine mechanically also. Both guns have been on the market awhile. The only difference with the XDm is that it is new in 10mm.

I don't understand, can't explain it.
I shoot Glocks fine, just takes more "thought" to do so. Doesn't have that "extension of the hand" as do other pistols... except the G20.
Loved that gun from the first shot and definitely (probably, we'll see) would be my choice in 10mm.

Weird. It's built like other Glocks. Does caliber change things that much in such a such a uniform platform? Perhaps. But I like the G20.

I'd lean towards the XD because I also struggle with Glocks. The grip angle just bugs me.

I wish S&W would offer their 5" barrel M&P 2.0 in 10mm. I think they'd sell like crazy.

I’ve owned both platforms, but not in 10mm. Currently have 5 Xd’s and 0 glocks. For me I liked the sights, trigger and grip better on the xd’s so those have stuck around. I too have been thinking about a10mm, but am hoping Springfield comes out with one in the mod2 style which I like better than the XDm.

My XDm Competition in .45 is the best-shooting .45 I've owned, and I've owned a bunch. I much prefer it to the larger Glock .45. If the 10mm versions perform like the .45s, I wouldn't hesitate to get the 10mm XDm. Especially if you can get in the same format as the "Competition" model.

As far as reliability, it's a toss up. Both are really good and reliable platforms for 10mm.

Aftermarket support, both are good but Glock I feel is better with more options should you decide to take advantage of it.

The Glock is a handful. That could be good or bad. If it's too much gun for your hand you won't like it but it spreads out the recoil a little more than the XD in MY hand. More comfortable to shoot with full house loads.

It comes down to personal preference. What do you like? Which fits your hands better? Which points more naturally for you? That's what should help make the decision for you.

I own neither, but I'd pick the Glock. It's been around for a long time and the 10mm is somewhat of an oddball round. Most factory ammo is probably in the .40 S&W range, but the reason most folks buy the 10mm is for hunting and are looking for .41 Magnum(ish) performance, often with hand loaded ammo with non-personal defense bullets.

If that's your intention, you'll be able to find lots of information all over the place from folks that have "been there, done that" with a Glock in 10mm. They'll be able to give you best practices and what works and what doesn't. You'll be searching in the dark with the XD, just like all the other XD folks are.

Of course, unless you buy a Gen 5, or an aftermarket barrel, the polygonal barrel in the earlier Gen Glock's may cause problems with some of those hunting bullets. That does give some advantage to the XD.

I don't own either, but I greatly prefer the feel of an XDM to a the Glock. I hate the feel of the Gen 3 G20. I prefer the Gen 4.

Honestly the egos need to be heavily considered, and would be the deciding factor for me. The XDm line is known to have good reliability and accuracy, and their CS is good in my experience. Same can be said of Glock.

Honestly thought, if I wanted a high capacity 10mm, I'd go for a hammer fired Tanfoglio as the price is similar or lower than the XDm. I was amped for the XDm, and then realized I'm not that keen on the idea of a polymer 10mm. Unless SA comes out with a 3.8" version of the XDm in 10mm to compete with the G29.

I have read on several forums that Glock has no plans to come out with any Gen 5 guns chambered for anything besides 9mm. Apparently the gen 5 design went back to an earlier design that will not tolerate repeated use of anything that recoils more than a 9mm. Unless plans have change, which may be.

I don't think we should expect a gen 5 G20, 29, or 40.

I agree about preferring traditional riffling for heavy lead loads. Polygonal riffling could limit a stock G20's utility.

I had a Glock 20. Great gun, but I couldn't shoot it accurately as the grip didn't work for me. I bought the XDM 4.5 a couple of months ago and shoot it accurately. It's a great option for me. You'll do well with either one. As others have said, pick the one you shoot best.

Trey Veston sums it up best. I had a G-20...way too blocky for my hands. I have a G-40 because I believed the adjustable grip would work for me...it is barely adequate, for me; my hands are just not big enough to comfortably shoot the Glock.

When the M&P came out, I couldn’t wait to shoot if. I took a friend to the range who was trying to decide which pistol she wanted, as opposed to what her husband was insisting she needed. We rented a Glock, the M&P, and a Springfield XD, which I had absolutely NO interest in shooting... In the end, I couldn’t have been more disappointed in shooting the M&P, and I couldn’t have been more surprised in how much I liked the XD.

I have both pistols.
I have put about 1k through my g20. It is a great shooter and I am not a glock guy. It is accurate and reliable.
This is the only 10mm pistol my wife will shoot.

I have not got the XDm to the range yet. I like the feel of the grip and the trigger feels really good.

I don't think you will regret which ever 10mm you pick. Good Luck

I picked up the xd to try some of my cast bullets in. I’ve got a Glock 20 and 29. I have the xd sold tomorrow. Throat is really short. Won’t feed cast any better than my Glocks. Trigger on mine has lots of mush but I’m used to the Glocks. I like grip on the xd better than the Glocks but I’m going to stick with the ones I can shoot best. Got a 19 and the xd in 9 mm and I can’t decide which one I like better since they both shoot great. Trigger on the xd 9 mm way different than the xdm 10. Maybe I got a lemon. For what it’s worth I don’t just shoot cast and never got to try any in the xdm.

When I got my Glock 20 I was more interested in the 10mm Auto than the Glock. This was back when there weren't near as many options available in 10mm Auto. As my signature suggests, I've been a fan of the 10mm Auto for a while, since before it was cool. The Glock 20 was one of the only options that didn't have reputation for battering itself apart with a steady diet of full power loads. It was one of the only options that wasn't limited to single stack capacity. And it was one of the only options that cost significantly less than $1000, more like half that. So I took the plunge. It took me a while to figure out how to shoot the Glock, but as mentioned, ergonomics are subjective.
As mentioned, the Glock 20 is more proven, more available, and has vastly more aftermarket support. Glocks are easy to work on, so much like having an AR-15 or a Remington 870, it is easy to get carried away with the upgrades. Over the years I have acquired a KKM Precision barrel because the tighter chamber helps preserve brass and a 20 pound ISMI recoil spring on a stainless guide rod to keep the my brass in the same county. Remember, I got into 10mm Auto back before Double Tap started the boutique ammo market that 10mm Auto thrives in, so the cartridge was a handloading proposition. Having your brass super stretched in loose Glock chamber and then tossed nearly into low earth orbit by the factory 17 pound recoil spring sucked. Since then I have added an extended slide stop and TruGlo TFO sights, which are awesome, BTW. The clip on beavertail only cost me $10, took 40 seconds to install, and has really saved my hands, as I have a tendency to creep up really high on the pistol and get bit by the slide as a result. Finally, a member here on the forum sent me a Phantom trigger for it, which is also outstanding, and which I also was able to install myself in minutes without tools because the Glock is like Legos for big kids.
The experience I have with the XD has been underwhelming for me. It certainly isn't a Glock-killer, to me. It seems to have a higher bore axis and be a little more complex under the hood, but this has been from experience limited to a few hundreds rounds, mostly through a 9mm compact, but a few rounds through a sub-compact .45, which I found to be snappy, and unpleasant. So yeah, between the Glock 20 and the new XD, I've already made my choice and don't regret it for a second. This thing is rarely more than an arm's reach away:

The glock 20 is what made me switch from XD's to glocks. I wanted 10mm and at the time Springfield didn't make an XD in 10mm. The G20 shoots 40S&W fine in the factory barrel. So I sold my 2 XD40's bought a 17 for cheap ammunition. My wife bought me a 26 then I bought a 42 and then a 29 . Honestly I carry the 42 70% of the time the 29 25% of the time.

one plus for the glock 20 is that lone wolf makes a 10mm to 40s&w conversion barrel. Friend has one and it has ran flawless. The conversion is just a range toy to get more trigger time with his g20.

Both are quality guns. Personally, I own the Glock 20 and love it. It's a Glock, so aftermarket support is huge and mag availability is common. I have big hands, so it fits nicely.

I have a g20 and large blocky hands so it works good for me. I've found it does not have quite the aftermarket support as the 9 and 40sw glocks, but it does have the glock support nonetheless.

I've not shot the xd so I cant compare.

Glock 20 is...just another glock. Thats a good thing to me, not to others. That said, they just work and you dont need to fiddle with it. Ive had my glock 20 3-4 years and carry it a lot. No issues, good capacity and a wide selection available holsters, sights, and all things glock if thats your thing. The XD never felt right to me and ill just say theyre not for me. Delta elite is sweet, but were not talking about that.
