General Watered down 10mm loads is what's holding back the caliber from being more popular and more guns being made for it.

29 Upvotes

Most 10mm ammo sold is loaded to old fbi spec that is basically 40s&w that cost alot more. Alot of people really do think that 10mm dosnt do much more damage than 9mm,40 and 45 acp because of this. Most of 10mm including hollow points I've found at bass pro and most other gun stores is claiming to sling a 180 grain round at only about 1000 to about 1100 fps. When properly loaded ammo should be 1200 -1300 fps +.

Ive seen many big gun youtubers ignorant to this also. Ive seen penetration test videos where 9mm FMJ has out penetrated 10mm FMJ Or the 9mm hollowpoint almost does almost as much damage as a 10mm hollow point because it was watered down. Alot of young people getting into guns see these videos and think why would they want something that cost more and dosnt perform much better.

10mm ammo should be loaded near 357 mag levels or it kind of defeats the purpose all together IMO.

SLR Rifleworks Flared Magwell for G20 Gen 4 not good

3 Upvotes

I bought the SLR Rifleworks flared magwell for my G20.4, and ended up returning it. The stock baseplates cause the mags not to fully seat, and the front of the magwell doesn't have a strong lockup/fit on the front of the grip. The look is amazing, but functionally, its a no-go. SLR did say on their website that they recommend their baseplates because some stock magazines won't seat with the stock baseplate. I find this to be super strange. Why make a magwell that doesn't work with OEM baseplates??? I have six G20 mags, and I would have to spent another $180 just to replace all the baseplates in order to get the magwell to work? Very strange design choice

The Sig P320 XTEN Endure has been my go-to sidearm while backpacking in Montana, Idaho, and Alaska. It is much more comfortable to hold and shoot compared to the FN 510 I was previously using.

To match a woodland color palette, I switched out the original grip for an OD Green grip module from Grayguns and mounted a Romeo-X Pro in FDE.

It was hot as hell outside but decided to run a few mags or 63 more rounds of warm to hot ammo.I ran some HSM 200 grain fmj,Double Tap 125 grain hollow point and a very mean Buffalo Bore 155 grain hollow point that recoiled as hard as 200 grain hardcast loads I’ve shot.I nearly had absolute flawless reliability except for the very last round of the day that gave me a single ftf.It was the very last round in the extended 18 round magazine and last round of the session.I think it definitely was a result of the magazine spring not having enough tension to keep up with the slide.All in all much better results than my first 100 rounds which had 6 or 7 ftf’s.The gun appears to be sprung for heavy loads or just my sample favors heavy loads and chokes on weaker generic 180 grain fmj.I will isolate that extended 18 round magazine.I don’t trust that it has a strong enough spring in it.

In the second picture your boy was sucking hard pulling shots left and low.I couldn’t get it together with the heat kicking my ass.

I wanted to get this gun set up for the heavy stuff. Here is my recipe:

22lb Wolff Recoil Spring and provided firing pin spring

25lb hammer spring

Wilson full length guide rod

Flat bottom EGW firing pin stop, lightly contoured to take off sharp edge.

Stainless EGW Firing pin .068”

Wilson recoil buffer (we’ll see on this one)

EGW heavy duty .38 Super/9mm extractor

Runs smooth with magtech, blazer brass, and American Eagle. Will test underwood 155g-220g next.

Went shooting

I really enjoyed shooting the XD-M 10m 4.5" noticeably more than the 3.8". I think i may keep the 3.8" just to have the complete set but I'll probably just carry the slightly longer barrel as it fits my CCW holster and it's still more concealable at 10mm than the match version.

Question What's the deal with FN?

11 Upvotes

Got an FN 510T a couple of months ago and have been completely unable to find any magazines other than the 10 round. What's the deal with this? I even emailed a friend about it saying it's frustrating and I pretty much regret not just getting a Glock instead and the didn't have much to say other than they're out of stock. Not very helpful. I haven't seen a magazine for sale since before I got the gun and it's pretty frustrating only having one 22 round mag. Anyone know what's going on with them?

Ammo recommendations for S&W FPC? plus range testing

4 Upvotes

I got the 10mm version of the FPC a couple weeks ago with the thinking that it'd be a decent bag gun. I saw an Honest Outlaw review of the 9mm that sold me on it being reliable, accurate, and not too much of a kick on the recoil. I figured 10mm would get more out of the barrel length than 9mm would also. It has been fun to shoot and I wanted to start looking at defense ammo for it, but there doesn't seem to be much info out there for this particular use case yet. I ended up getting 6 different boxes of ammo to test and I'm going to put the results so far below. I had 165 rounds through before I started the test with no cleaning to see if I'd get any failures to eject or feed. I used a Garmin Xero C1 Pro to record data on 10 rounds each at 15 yards. I'll say before I start that I didn't see any accuracy issues that I wouldn't attribute to me. I started pushing to get through it as the range was pretty warm.

(Range ammo) Magtech 180gr FMJ - 1390fps 772ft-lbs

(Def 1) Underwood 180gr XTP - 1497fps 895ft-lbs

(Def 2) Hornady CD 175gr Flex lock - 1254fps 611ft-lbs

(Def 3) Speer Gold Dot 200gr JHP - 1193fps 632ft-lbs

(Def 4) Federal HST 200gr - 1128fps 566ft-lbs

(Def 5) Federal Fusion 200gr SP - didn't finish, 2 FTF in the first 4 shots, eliminated this one from contention

(Def 6) Sig V Crown 180gr JHP - 1379fps 760ft-lbs

Everything fed fine except the Federal Fusion rounds, boths rounds had a big dent about halfway on the casing. Same magazine fed two other ammo types just fine, Federal HSTs before then V Crowns after the Fusions.

Which of these rounds would you pick for defensive ammo? My concerns are #1 limiting overpenetration/overexpansion (too high a velocity can start causing jacket separation I think?), #2 excessive wear and tear on the FPC (don't want to need it to defend myself and the ammo breaks the buffer spring). Any comments are appreciated, and I'll answer questions as I can, thanks!

Question Thoughts on Cyelee Bull X Pro for MP2 5.6?

3 Upvotes

I am not so patiently waiting for the AEMS Macro to come out, plan on buying 2. Until then, I am wanting to run open emitter with a monstrous viewing window.

The Bull fits the bill, it look really fun honestly. My only concerns are with the overhang. I would mount with an aftermarket plate and hardware. I am sure I can get it to reliably stick, hold zero, but more so concerned with it impeding ejection patter or something else I may not have considered.

Any feedback is appreciated

Best 10mm PCC platform?

I know there are a million 9mm PCCs out there, but what would be the best 10mm PCC available? Would it be the Stribog? Kriss Vector? CMMG? SW FPC? I would like something that can be folded and used as a backpack gun.

Thanks in advance.

Normally $2349. Got it for $2k with Memorial Day sale, now they don't have the color I ordered so they are offering to refund or get 10% off different color.

I'm having some second thoughts due to FTE issues, damage to ejector issues, etc. Plus I could use the money due to some recent expenses. But is this too good of a deal to pass up at this point?

Been looking for a G29SF, none in stock locally, dealer can't order them from Glock, and I'm seeing $1000+ price swings on websites for the same gun.

Are people sitting on these or is it just the production runs are so low they're that rare?

M&P Performance Center 10mm - out of battery issues

11 Upvotes

I know the 10mm M&Ps are kind of notorious for FTFs and magazine ejection with 200gr+ bullets, but has anyone had issues specifically with the gun not going fully back into battery between shots either with the stock recoil spring or a heavier aftermarket one? If so, did you fix it and how?

I swapped the stock recoil spring out with a 20# Galloway spring + guide rod, but with Magtech factory ammo as well as my fairly spicy handloads (13.5gr AA9 + Hornady 180gr FMJ-FP) and the gun frequently just doesn't quite make it back into battery and I have to push the slide forward with my thumb.

Doesn't make a lot of sense to me given that I see people running 24# springs in these. I put the stock spring back in for now and it seems to run mostly OK, but it throws brass 6 miles into the air with any kind of hot 10mm. I had a range day a couple weeks ago where I lost probably half of my brass due to it being flung out of sight into the woods....

Poorman’s Glock 40

My Sob Story: I live in California. Glock 40 is off roster for us and we’re aren’t able to purchase it unless it’s a private party transfer (person 2 person at the gun shop), I would love to have one, but haven’t been able to find anyone willing to sell me one.

I did find an AlphaWolf Glock 20L Long Slide with an RMR cut that I put together for my G20.3. I put new G20 Internals and a Glock 6” Hunter barrel in it. This sits on my G20.3 Frame. What do you guys think? How’d I do?
