So I gave in and bought a Sig X Ten, I already had the 4" M&P 10mm so a side by side comparison at the range was in order.

Just handling them the Sig is roughly 5-1/2 ounces heavier and an inch longer than the M&P but subjectively it feels like a bigger difference. The only way I can describe it is like an all steel 5" government 1911 compared to a lightweight commander sized. The Sig is also more nose heavy than the Smith.

Shooting them I actually prefer the ergonomics and grip shape of the Smith. I prefer the grip texture of the Sig, especially shooting heavy loads. The more aggressive grip texture of the M&P can be felt shooting heavy loads and it can be a little grating. The trigger on the Sig is much better, it's lighter and does not have the long take-up like the Smith. Initially I was shooting smaller groups with my Smith than I was my Sig, but that changed the more I shot the Sig and the group tightened up to be slightly smaller than the Smith.

Reliability, the Sig was 100%, the Smith not so much. Ammo shot was Blazer brass 180gr FMJ, Aguila 180gr. FMJ and Underwood 220gr hardcast. The Sig really likes the Aguila shooting the tightest groups of the night with it. While I like the grip shape of the Smith, the Sig handles the heavy 220gr. Underwood loads much better. The wider grip soaks it up and the grip texturing isn't abrasive.

The Smith, well it disappointed once again. I seemed to have fixed the consistent 2nd to last round in the magazine jam, now I'm getting random failures to feed. 2 failures with Blazer and 1 with Aguila. Previously is would jam the nose of the second to last round in the magazine against the barrel hood. Tonight is seemingly random with the base of a live round still held in the magazine, the case being perfectly horizontal and the nose of the bullet jammed against the feed ramp. Slingshotting the slide would eject the jammed round and chamber a new one. One thing I also noticed while shooting the Aguila was deep indentations in the middle of the fired cases.

Disappointing, 2 weeks ago 3 of us fired 400 rounds of 7 different ammo types including Blazer brass that was shot tonight without incident. First time ever I was Abe to run a full magazine thought it without failure. The gun has been sent back to Smith twice for warranty repair with the barrel being replaced once, I've replaced the recoil spring with a Galloway Precision 24lb. until, replaced the mag spring with Wolff Extra Power springs for the M&P .45 magazines, polished the feed ramp and chamber myself. I thought I had it fixed but with 3 failures in 150 rounds tonight, I still can't trust it.

Really annoying in that I thought the Smith was reliable and ordered a custom holster for it yesterday. I'll be calling them in the morning and see if I can have it made up for the Sig instead. The lighter weight and smaller proportions of the Smith would make for a better carry gun, I just can't trust it. I am happy with the Sig, 100% reliable, a good trigger and it handles heavy 10mm loads well.

Do Not be a beta testers specially after so many others have had issues with a M&P 4" 10mm !! But some are slow to learn I guess .

Do not expect others to feel for you ether . 10mm really is a mediocre power cartridge even with a heavy hot loads for seriously dangerous game .

I've had this pistol for almost a year now, so yeah I was an early adopter. The 4" M&P 10mm really is unique in size with nothing else comparable, that's why I was willing to take the risk with it. I've been updating on this forum of the issues I've had with it, returns to Smith & Wesson and, "Fixes" that I have implemented.

Not expecting others to feel for me either. Not looking for sympathy just trying to update other forum members who might be looking at one. Yes other handguns carry more terminal energy than a 10mm, I have some. But, 10mm autos tend to be lighter to carry than big bore revolvers and shooters can usually get more rounds on target with one. And if I'm truly worried about dangerous game, a long gun is going to be involved in the equation.
 
I cant imagine why there is such a massive difference in reliability between the 4" and the 4.6" versions, but it seems like they're opposites. I've been reading about people having nothing but trouble with the 4" 10mm. Meanwhile, after about 800-1000 rounds I've had one failure in my 4.6" with pmc ammo(and I've shot a few boxes of the Underwood 220gr hardcast). Others seem to have the same or similar experiences with the longer barrel model. I wonder why they seem so different.
 
I am surprised that the Sig shot the Underwood 220 cast without a problem. The Sig forum is full of comments about large flat nose bullets (and some round nose) hanging in the magazine and preventing the follower from pushing up. It looks to me like the nose of the bullet is hanging in the mag latch cutout on the right side of the mag. I finally got mine to feed most of the time by seating the bullet deeper than I do for any of the other 10's that I have had. That required a reduction in the powder charge and also resulted in less accuracy. It was a tack driver until then.

I wonder if it has something to do with the lighter slide weight and increased slide velocity that might bring about with the 4" version?

Guess you missed the XD 10mm 4" for 3.8" compact and 4.5" full size models . If you feel the need for a heavier pistopl in ther wilds a cross chest holster OR suspender help to lighten your load ! Heck I've carried a 46oz revolver many days in the field in a cross chest rig . For personal defense the 10mm is still not really special except in some buyers eyes . Some buy it cause its cool !!. So you've had yours for a year . that means it had 5.5 months in the market for others .to complain about ?

Anyhow good luck with siggly , One more company with a history of beta testing the p320 and p365 . maybe that long barrel version your bought helps it run well so far .

I got my 4" M&P 10mm in February and it has been wonderful in every way. Perfectly reliable, great feel, and very accurate. The trigger is better than any striker fired gun I have ever shot and better than my Sig 365 and a lot better than my Sig 365 XL. I hated the looks of the big sights but they REALLY help my 64 year old eyes and my shooting and the recoil is not bad either. It sounds like Smith & Wesson had a few bugs to work out of the design but my gun has been perfect and I think a lot of the current guns are better but I wouldn't buy one made before 2023 from what I have heard. I have not shot the Underwood 220 grains and probably never will because a 20 round box of it costs about as much as 150 round rounds of 9mm.

Because it's not a large volume case capacity cartridge. That's what you need to push heavy for caliber bullets fast.

That's why the 10mm Magnum was invented.

But for what it is it does pretty good. Not a 41 Magnum like some try to compare it to but full loads are anything but mediocre.

From my 5" M1006 I've chrono'd handloaded 10AUTO 165gr JHP at 1433mv // 752me.

From my 8" CMMG Banshee I've chrono'd them at 1542mv // 871me.

That's not mediocre to me. Maybe it is to you?

Cartridge or handgun fan boys are always worth a good smile on my face as they work so hard trying to prove a certain load is all that as far as terminal performance goes too its just one of many others .

Oh the 10mm mag still not all that ether except for some 10mm fan boys .

What's the price difference between the X10 and M&P10?
 
I own 2 M&P 10mm pistols a recently purchased an Sig XTen Comp. I purchased my first M&P 10 in early 2022. I was the PC model with the comp and 5” barrel. I couldn’t get a mag through it without a FTF. I finally got it sorted out after a trip back to Smith and a little trial and error. Smith replaced the mag springs and polished the feed ramp. It was better but still had a few issues. I swapped to a 22lb recoil spring from Galloway and never had another issue with range ammo or 200gr hard cast. I’ve put over 2000 rounds through that gun with out issue.

I bought the Sig when they first came out with the shorter barrel and comp. It has been a fantastic gun for me with no issues. The only problem is it’s heavy and the slide is wider than a standard P320 so finding holsters was a little hard at first.

Looking for a lighter compact 10mm, I ended up getting another M&P in 4 inch. I bought this gun in March 2025 (getting a free Viridian optic was a selling point). Smith must be following these forums because it was been flawless. Over 1000 rounds without a hiccup! I hope it stays that way!

Why 10mm for me? I live in an area with grizzly bears and spend a lot of time in the high country. 10mm seems to do well against large animals with properly placed shots. Having 16 rds vs. 6 with the revolver I used to carry, seems like a better, safer deal.

I just sold my Sig X10 and bought an S&W/M&P Compact 10mm due to the rising number of unwanted discharges involving Sig P320's. The number of incidences is known to be ~120 as of now. I'm a Sig aficionado so the decision wasn't made without some regret as given all evidence, I still am unsure who's at fault... user or firearm. With that said, I made the decision to err on the side of safety. Chicago P.D. just issued a full-stop on carrying P320's.

Given the aforementioned, thus far the S&W hasn't disappointed at all though.
 
I love my M&P compact 10mm, and it has become my favorite handgun and I have over 20 handguns. Great feel, accuracy, controls, and 100% reliable and also those tall, weird sights are great for senior eyesight.
