SIG P320 XTEN (10MM) REVIEW & ACCURACY 

@@mrjones4249, are you in Washington state?

@@62dobie yes

There are a few high capacity 10mm. Springfield and Glock are starters. Smaller gun makers have offerings as well but are not commonly seen but quite reliable. Issue here is brand blindness to a few makers. I forgot to add S&W came out before SIG offering. SIG, HK, and Keltec are last to playground. The latter two MIA.

I would hardly consider 15+1 “high capacity” but I recognize that other 10mm offerings don’t have 15 round mags so I think I see your point.

Far as recoil that's because it's a 5in barrel

I want to know if the aftermarket will support the magazines In carbines for the sig to have a cross compatibility between a carbine and a pistol

What holster did you go with? Do you feel the difference with the comp slide?

Yeah it’s almost always break in period on the magazine. New sig mags are always kinda stiff

M&P is not as strong.

I got the M&P and I'm gonna sell it. Doesn't run hot loads.

They need to be very stiff for 10mm, especially when running hotter loads. Otherwise the slide velocity outruns the magazine and you get failure to feed jams. That’s what’s happened to many of the early M&P 10mm guns because Smith & Wesson used weak mag springs on the first batch.

Fwiw - my targets were full power loads: Underwood 200 grain hardcast

Good question. I have been cleaning Sig FCU's since they first come out and never had a problem. Normally I use a light coat of Rem-Oil and make sure to wipe it down dry. These get pretty dirty and don't need to run wet so what Sig recommended makes sense to me. It you keep it wet after cleaning you are likely attracting more gunk into the FCU so to me at least, keeping it dry after cleaning seems to have worked well so far.

@@AZTrigger I've found Hornady One Shot works very well to essentially "dry lube" components. Doesn't attract gunk. YMMV.

The 9mm version

Congress tried to ban 10mm......but they couldn't match its power.

But will it kill a grizzly with one shot? Or will you be bear lunch?

Agreed - although based on the cost of the conversion kits to date, not sure I see the value in them...unless you live in a state where getting another serialized handgun is a lengthy and arduous task. In free states, it has been relatively easier just to buy another complete handgun.

Not really a point when there's the 9mm and 40. P320 already. From a manufacturing standpoint it's kind of pointless also.

Look up ab prototype

Same. A five inch double stack aluminum framed 10

Bike tire tube. Good ole sf mod

It does. Check Hogue.

Good question? Bought a KKM barrel to do the same with my Glock

@@bonitahalpern5424 I had done the same KKM, lone wolf barrel was crap, made the glock 40MOS a jam-o-matic

Good question

It is actually more supported under the feed ramp than my Dan Wesson 1911’s in 10mm. I literally had to buy the Sig to find that out since nobody talks about it.

Yup - good point. They can be a little tricky to add to the P320's over the P365's and you also need to make sure your grip module has the cutouts for them...unless you want to make the cutouts yourself :-) sigsauerparts.com/sig-sauer-p320-manual-safety-parts-kit/

Correct. I meant the first 10mm in the P320 line. My bad and thanks for the correction.

Yea all solid steel, this is Sigs FIRST 10mm as seen in video polymer pistol. 15+1 in a 5 inch barrel is a beast!

@Dale Ross Name Sigs 10mm thats polymer.....I'll wait

@Dale Ross The R1 is a aluminum and steel pistol bud, IT'S NOT POLYMER!!!! I am just waiting on my NCIS check and about a week I will have Sig Sauer's FIRST POLYMER 10mm. Thanks for showing the internet how smart you are troll

FWIW: 10mm has become earlier to find here in AZ over the past few years and for target loads (S&B) price is on par with 45 ACP.

Here’s the real problem with the 10mm. Unless you load your own ammo, or buy Buffalo Bore, you don’t get to use the potential that the 10mm brings to the table. Factory 10mm barely surpasses factory .40 S&W in performance. It’s a ripoff to be honest. Luckily, I’ve been a handloader for many years.

@@bigbore4498 I understand your point and I am a big fan of Underwood Ammo for that reason. That being said, I have fired both 10mm and 40SW out of the same Glocks at swinging steal targets and I can assure you with most commercial rounds there was a noticeable difference in the reactive targets.

@@AZTrigger And I don’t disagree with you. There is a difference on reactive targets. It only takes around 50-75fps when shooting pistol rounds to notice a distinctive difference on steel. But factory ammo, by pretty much every measure, is anemic. Thats why you see the difference on the steel. Hornady says their 180gr XTP in 10mm is 1275fps and their 180gr XTP is 950fps. I’m sorry. But that’s abysmal external ballistics. My 180gr Noslers chrono at ~1480fps and my 220gr hardcasts chrono at ~1260. I won’t give my load data on YT. But I’m not at max. And that’s out of a 1911. And that’s why I load. Well, and the savings. I can load premium ammo at prices you can’t buy the cheap stuff for. I can load specifically for my gun. And I can get the performance that the cartridge offers. This is true for PC as well as RC. But it really shows up in the PC when you talk about 10mm and 44mag. And holy crap the difference with 45 Colt is ridiculous. For the unlearned, casual shooter, it probably doesn’t mean anything to them. They’re punching paper at an indoor range or plinking steel outdoors. But carry my 10mm (and other larger calibers) for real protection against real threats (2 legged and 4). I want every bit of performance I can get. I’m glad you mentioned Underwood. For the life of me I couldn’t come up with the name when I was mentioning BuffaloBore. Kevin would definitely be disappointed. Great company. I’ve tested their ammo in working up my own loads. I’d definitely trust it.

No better way for it to gain popularity than for you to buy a 10mm

I love my SA XDM 10mm elite. I just purchased this today. I don't see it replacing my SA XDM 10mm elite as my edc. I do see it on my nightstand.

FWIW, I used to add slide release extensions to my Glocks and I find the standard P320's are similar in size to my Glock extensions. In short, I have zero trouble doing one-hand releases on the XTEN.

@@AZTrigger Good to know!

They wear in with time . And they are not somthing you have to use ?

FWIW: I can handle the slide release with one hand find on the XTEN. I start the video doing just that at the range.

if it's anything like the m18 it won't be great. Hopefully aftermarket gunsmith barrels will come out for it.

I run a KKM barrel + comp on my G40 & the damn thing may as well shoot lasers.

The XDM 10mm Elite is built like a tank.

@@TLhike, links to more than two, please.

Springer precession is making a custom drop in trigger that comes out soon, they’ve already got a lot for it but this one is made pacifically for the elite, but I’ll probably shoot it until I break it

Xdm elite

As bulky as they are, my 10mm Glocks have never given me an issue. I just wish someone made a concealable 10mm. Ive been carrying a G20 for a few months & come to realize that its simply too large. I just bought a Hellcat Pro until I find a 10mm I can actually carry comfortably & trust.

@@sofloflow Glock 29.4 or XDM Elite 3.8 Compact 10mm.

He only had feed issues…which is almost always indicative of magazine break in. New sig mags can seem a little stiff. I always store new sig mags fully loaded a few days before range day.

ya , that was Glock-bashing at its finest. G20 since 92, zero issues of course

Just bought the 4.5 Elite. Cant wait to shoot it

@@pole_barn_builder the compact, in my opinion, is superior. But I like a gun to concealable so that obviously gives it a leg up on the 4.5”. But I’m hoping Sig does drop a Compact in 10mm so I can run it vs the Springfield.

Yea I LOVE mine!!! It's a beast!!! I have the Holosun 508T green dot on mine, I have the Springfield 4.5 in 10mm too so it's going to be choices, choices for me lol I may swap in the 4.5 in for this Sig IDK

My dad bought one a year ago still waiting to shoot it only thing I don't like is the sights and the mag well flare but I can just take it off

@@yeetergriffin1586 yeah take the magwell off. Makes it far more comfortable to shoot.

With a 4lb trigger striker fired pistol, I would highly advise against using a leather holster

@@PeterYi thank you for your response Peter, why do you advise against using a leather holster for the Sig P320 X10 ?

Wear is to be expected of any tool that is used frequently.

Good question. I am checking with my contact at Sig now about this. Hopefully I will have a definitive answer shortly...

James at TFB said they're one way backwards compatible. X10 works in p320, not the other way around.

@Dale Ross - I wouldn't bet on that. That is why the question was asked.

@Dale Ross - Settle down before you have a stroke. Glocks have been around for 40 years and have proven their reliability over and over again in that time. Like it or not, they are the standard that others are compared to. SIG releases a similar pistol in what is a brand new, unproven platform and it is natural and reasonable to ask the question. If you have an emotional reaction to that, that means you have no faith in your answer that it will last. I have used Glocks in law enforcement for a number of years. I have also used my 10 mm as a backwoods gun on numerous occasions both on hunting trips in Alaska as well as regular camping trips. You also have to acknowledge that the P320 series has had some crazy teething pains. I certainly would not trust it with my life or anyone else's. Usually people that have problems with Glocks have played with them far too much and changed too many parts out for them to be reliable anymore. Ironic that you complain about Glocks being cheap pistols when SIG got their contract based on how cheap their pistol was.

I've shot Glocks for 22 years and sigs for 15. Only had one glock break and that was a 22 in 40 s&w. After about 8,000 rounds. 15,000 rounds out of my sigs combined. Both companies are great in my opinion, but not perfect. Let's just be real here and admit both do good work.

@@jordansvennes5587 - Yeah, I used a Glock 22 going through POST and had issues with it as well. It never should have been loaned to me. But the big deal about the 320 variants that I don't like is that they are built to a price point. That makes me worry about reliability and longevity.

@@rickgrimes931 It is a concern. I honestly feel like the 320s won't last as long as a glock in the bigger calibers but hey that's a wild guess. I have put 2000 rounds through a 320c in 45acp and it's ran flawless.

Nothing really, but some of us (me) have a hatred for rear grip safety's. I want the XDM 3.8" 10mm so bad, but that rear grip safety kills it for me.

@@sofloflow sorry to hear that, I have had my XD's since the beginning and love them and never had a problem with them, very reliable 8k rounds and counting, I also like the grip better than most. I think you should give it a chance you just might like it.

The XDM has a defective trigger with a trigger safety deactivate that is plastic and will break. It broke on one reviewer already. Springfield will need to redesign with a new material for durability/reliability. I almost bought the XDM, but now, hell no

Throws fired brass 25 plus feet behind, at about the 4 o'clock position. Shooting outdoors I lose over 75٪ of the brass. Bummer.

This is a scam

MSRP is currently $799

@@AZTrigger wow that’s crazy

They're going for over 1,100$ right now.

That’s not bad

Don't make the Sig guys mad🤣😂you know how they get when you mention anything about Glock 😂🤣

@Dale Ross Triggered? 🤣🤣🤣

@Dale Ross You’re right. Sigs can’t even compare to how much better a Glock is! At least you’re PRO2A. 👍🏼

I prefer sig but I'll never knock glocks for reliability or quality but I know it's a stupid reason but I just wish glocks weren't so ugly I'd happily carry a glock but they are such eye sores and in all honesty I'd rather have a 1911 over either

Because it's new doesn't make it a master piece.
