[ARCHIVED THREAD] - Is .40 just naturally prone to failures to feed? (Page 1 of 2)

Posted: 3/28/2021 1:30:42 PM EDT

My experience with .40 guns is that they all had a failure to feed at some point. The round was under the extractor and bound to go in to the chamber but it just didn't make it.

My guns in 9mm have always fed fine.

Never had a failure in mine, S&W POS. Old Police gun, shoot it fairly often.

This. Never had a failure of any sort - glocks 22, 23 & the M&P full sized either.

That’s a new one. My .40s work as well as my 9s.

I have never had an issue with any of my .40s

To give a little context: Glock 22, Glock 23, S&W M&P. Not often, about 1 in 300 or 1 in 600 rounds roughly.

I have FNS, M&P, and CZ pistols in .40. Only the M&P (after installing a Storm Lake barrel) and one CZ (P07) have had a failure to feed. The P07 only after I shortened overall length of the cartridge to make them chamber in the Beretta.

Glock 27 and XD Tactical. Never had an FTF.

Sample of two but there it is.

Since 1994, I've carried at various times S&W 4046, Beretta 96 (D and an FS Centurion), G22 (one each Gen2, 3 and 4), and a G23 either on and/or off-duty. Never had any failure to feed with any of them.

In this thread we learn that OP is a limp wristing sissy

I'm only partly kidding, if you are having a consistent issue you need to start looking at the gun/ammo/mags/ yourself in no particular order.

Posted: 3/28/2021 2:43:28 PM EDT

[#10]

Umm no.

Now if you don’t replace mag springs or recoil springs when they wear out or use garbage magazines then yea, you get problems.

Posted: 3/28/2021 5:56:28 PM EDT

Never an issue in my p229. Not even with my crappy handloads.

Posted: 3/28/2021 6:15:08 PM EDT

[#12]

I've owned Glock 22's and S&W M&P 40's. Never a feed issue.

The bastard step child of the 10mm should have never happened!

An attempt to fix the shooter problem of handling the hot 10mm loads.

Once again the FBI spawns a reverse fix to a training problem.

i.e. : subsonic 147 gr 9mm, reduced recoil 12 ga shotgun buckshot, .40 S&W (40 short & weak).

I’ve never had one with a .40, I’ve had a few with 9mm and 45.

Posted: 3/28/2021 7:11:39 PM EDT

[#15]

None of my S&W's, Berettas or Tanfoglio have had problems. OTOH in a 1911 without a real .40 mag (with the spacer in the rear) they jam. If I use 10mm mags and they FTF.

Posted: 3/28/2021 7:15:13 PM EDT

[#16]

That’s because people who shoot 40 SW are more likely to limp wrist it.

My para in .40 eats everything with a vengeance. Must be a Glock thing.

Never has an issue with my HK USP 40.

The issue was never hot 10mm loads, the load the FBI was using in 10mm wasn't "hot" but the gun it was chambered in was BIG. That's where the problem was, the size of the gun, not the recoil. That's when the .40 came and saved the day. Not because FBI agents couldn't handle a mid level 10mm in a big, heavy gun, if anything it would recoil less than a .40.

Only one 40S&W failure to feed in many thousands of rounds through about eight 40S&W pistols. That was a Ruger SR40 that was dry as a bone. I lubed it up and never had another issue. As others have said, I have had more issues with 9mm than 40S&W.

No issues here- Glock and M&P .40s.

Yes, 9mms feed fine.

The .40, being but a chopped 10mm, has a history of being feed-finicky (especially in 1911s), unless long-loaded closer to 10mm COAL.

The 10mm is close to the .45acp in COAL and so feeds reliably in both single- and double-stack platforms.

I have never had an issue with either of my two .40s. SA XDM & G27

No, it isn't.

I had failures to feed in one LE trade in M&P40. I replaced the recoil spring and it improved. I tried new mags and it was 100%. Replaced the springs in the old mags with new Wolff +10% and it's been 100% for a couple thousand rounds.

I don't think it had anything to do with the .40 round, but just the springs were worn out.

I have a USP 40 that won't feed with a one new ten round hk mag. It works with my other mags. It is a beat to shit old police trade in

Been shooting 40's since I got my first one late in '93 & have all worked great. Ruger P-91, HK USP 40, Steyr M40 & Several Glock 23's & 27's . My friend had a Lama that was a bit more prone to jams & when I first built my P80 G23 it had a few hiccups but has been working great since then. I've noticed a lot of people really limp wrist 40's since they've been told it has this horrible kick & that can cause feed issues.

Ran a few thousand rounds through my Glock 24 (40 long slide) for awhile- no issue, same with my G27, and SR40c.

I had two police trade-in Walther P99 in 40 cal. One of them had issue when I used slide release , round would nose-dive into feed ramp causing a jam, the other one had no issue regardless. Sent it back to Walther and they gave me a brand new one. That was the only issue I had with this caliber.

Nowaday I enjoy shooting this caliber more out of my G29, G40. I don't have large hands but Glock Large frames fit me nicely.

I have two H&K .40s that are as reliable as anything else I've ever owned.

Good to hear that the general consensus is that they're not naturally prone to it. Good responses to this thread.

The only time I have ever seen a .40 S&W pistol not operate properly since it the round was invented, was either limp wristing by the shooter or crappy reloads.

Glock, M&P, & a Sig 226 all without a single feed issue (no cartridge issues at all with the .40 S&W in factory loads)

I have;

Glock 22 g4
XD40

S&W Shield .40

I can’t say I have particularly noticed any failures of any kind with any of them

Don’t shoot 40 anymore since I went to buying ammo in bulk and standardized on fewer rounds but when I did I never had a persistent issue with it. Worked in my guns, I’m sure I had a few malfunctions but nothing note worthy or consistent.

Posted: 4/2/2021 1:34:57 PM EDT

[#40]

Never noticed.

Sounds like a defective gun.

Posted: 4/2/2021 7:02:58 PM EDT

[#41]

Before we switched over to 9mm, we put hundreds of thousands of rounds through hundreds of Glock 22s, 23s, and 27s with virtually zero failure-to-feed issues. There is nothing inherently wrong with the round that would cause failures to feed.

What ammo are you using? Is it just brand/type of ammo, or multiple?

Posted: 4/2/2021 8:08:45 PM EDT

[#44]

Been a while but for me yes. Only ever had one 40, a Glock 27. Don’t know if it was the flat nosed ammo or limp wristing but rounds would stop on the feed ramp. Never happened with defense ammo. Really that’s the only gun I had that would jam occasionally that wasn’t a problem gun.

No.

What guns?

In what condition ?

.40s do usually require recoil spring changes at about half the round count that 9mm’s do.,

My department issued Glock 22 for over twenty years.

I’ve fired tens of thousands of rounds through 40 caliber Glocks without issue.

Classes, training and competition.... gen 2-3-4.... flawless.
