Pistols That Constantly Jam

I had a Colt XS Commander that jammed on everything. I literally couldn’t get through a magazine without some kind of failure. It didn’t matter what I tried to feed it.

Not a total loss. I learned a lot about 1911’s getting that thing to run. When I sold it, it did run very well.

Same with me. No matter what ammo this pistol was offered it suffered one failure to feed after another. I never went back to a Colt product.
 
I had a glock 30sf that jammed all the time. i liked it as a CCW. but jammed too much for me to carry it. i tried all kids of ammo.
 
The only pistol I've had failures to feed and failures to extract has been a Glock 36 45ACP. Sent to Glock for repair replacement and no help. Jammed 2-3 rounds per magazine. Worse pistol in Glocks lineup with complaints. It worked fine with factory and reloads for a short time then went south. Don't buy a G36 as your chances of a bad one is 50%.
 
How many out there have pistols that jam? With factory ammo? If so what ammo were you shooting excluding reloads.

I have a Colt Defender that always jams. I also have several of the original Kel-tec p40's some of which jam but I bought four (mostly for spare parts) so I have at least one that works ... recoil is horrendous ... I use my .44 mags as a warm up :)
 
My brother had a Mauser HSc that was imported by Interarms back in the '70s that could readily be expected to jam constantly too.

Ditto on the jamming Mauser HSC, had one myself years ago. As someone mentioned above, I won't abide a jammer.. be it pistol, shotgun, or rifle.

I have a 70s HSc that runs great! It will stall on some JHPs, but will eat FMJ all day. My recipe with XTP seem reliable, too. It's beautiful, so I let it stick around.

The one I have issues with is its fat and homely sister, the Mauser HS80 (Mauser contract, Spanish made double stack 380). It feeds proper, and fires fine, but the rest of the cycle is a crap shoot.
I want to love it, so I tinker with it sometimes until I'm sick of it, then back to the safe it goes. Haven't touched it in years actually.

Edited to add:
Oops I'm a dingus.... The HS80 is Italian, not Spanish.

My brother had the feed ramp polished on his Mauser HSc but that didn't help any, it still would jam with FMJ ammo. I remember the Mauser HS80 with a double stack magazine but I think it was made in Italy by Renato Gamba.

, sounds like my G30. sent it back, they said nothing wrong, it was "ammo related". i tried every factory ammo i could get my hands on. nothing worked. So much for glock "perfection". There isnt much between the 30/36. There must be a flaw in the pistol some where

I knew that.... I, uh...was just testing you. Yeah, that's it. :confused:

I only knew that because I remember looking at one at a gun show and thinking that this was even wider and heavier than the original HSc. It was well made and decently finished; just not a good fit for my smaller size hand.
 
My little Glock 42. No matter how much I liked it, I never could get it to run 100%. Disappointing. Replaced it with a S&W Performance Center 642, it hasnt malfunctioned once. Go figure...:rofl:
 
Mosquito for the win for me! Been back twice, have the extra mags "....proved to be reliable at the factory test bench." Twice. I only use it now to prop open the door on the small safe inside the larger safe...if the safe door accidently closes, my hand is safe because the Mosquito will catch the door when it falls. Well done GSG!
 
Kahr P380. To make a long story short....after 3 trips to the factory, it was replaced. 2nd one is a lot better, but still has problems (FTF and FTE) so I don't trust if for CC. Sad.
 
I bought a AMT auto mag II came with no mag. SO got two off some internet place . after messing around with the mags . I can run one with no jams but the other will still jam on the second shot every so often . Much better then when I first tried,,
jam every two or three rounds .

My Glock 42 would not eject my reloads that work in numerous other 380 ACP Pistols that I have. Velocity is nominally the same as factory in the other guns. I know, reloads are not part of this thread.

Today, I ran a box of Winchester white box flat nose through the Glock 42 and all fifty cycled the gun without any problems. I guess the gun is finicky.
 
I have had one: a stainless Walther PPKs comes to mind. My brother had a Mauser HSc that was imported by Interarms back in the '70s that could readily be expected to jam constantly too.

My S&W Walther PPK in 380 ACP performs flawlessly with round nose bullets, even my reloads.

Hollow points and other odd shaped bullets do work worth a darn. Since I prefer penetration versus "a hope of expansion" with 380 ACP, round nose bullets are just fine with me particularly when you factor in the reliability.

I have one of the early production Sig P238's that was un-reliable until Sig made several iterations of the magazine and replaced the recoil spring with a flat wire spring. Sig failed to leave enough room in the recoil spring cavity for the round wire spring when compressed. Current production P238s are about as reliable as a light switch.

Except for a Gold Cup that I got recently, I've never been able get a 45 ACP 1911 work with 180-200 grain semi-wadcutters.

My experiences with 185 gr. and 200 gr. semi-wadcutters have been somewhat the opposite; my Officer's Model ACP, Combat Commanders, and Government Models love them. My Gold Cup did fine with the 185 gr., alright with the 200 gr., and never really cared for any 230 gr. ammo.

My stainless Walther PPKs fed most FMJ ammo but didn't care for any JHPs. It also had a tendency to drop it's magazine on occasion, the DA trigger was very heavy and gritty (the SA trigger was nothing to write home about either), and the overall fit and finish was definitely not up to past Walther standards.
 
I had a Mauser HSc 30 years ago. It was a jam a matic. From the responses on this thread HSc seem to be the winner in the looser category. I also had a Walther PP in 380 that was unreliable at best. Recently I had a Sig made in NH that was so bad Sig bought it back when I sent it in for repair. Old German Lugers were notorious for jamming.
 
I have a Springfield Armory 9mm 1911 national match with a 4 digit serial number, first year of manufacture (1984). Really pretty gun with deep gloss blue finish, target sights, and colt cocobolo grips. I got a great deal on it and I soon found out why. It would not cycle anything to save its life and the trigger was like 15 lbs.

I took it apart to find the hammer and sear were all chewed up and wearing against each other. I think someone attempted a trigger job and cut through the hardening and the soft steel underneath was wearing badly. Either that or they were never heat treated to begin with. The outside of the gun looks great but every part inside the gun looks like it was machined in a North Korean prison out of melted down soup cans. Its the worst workmanship I have every seen in any gun ever, bar none. I replaced the hammer with a remington, the sear with a wilson, new springs, a GI A1 mainspring housing, cleaned up and smoothed the remaining parts and did a nice 3lb trigger job on it.

Onto the feeding problems, you could not get 3 consecutive rounds of FMJ ball ammo to chamber. Same every time, the round would nosedive a bit in the magazine and run straight into the feed ramp and stop. It has an unramped barrel and the feed ramp on the frame was almost vertical and there was a very defined edge from the feed ramp to the barrel ramp for the bullet nose to catch on. I tried reshaping the feed ramp and new magazines with no improvement. Finally I broke out the TIG welder and welded a new ramp onto the frame with stainless steel filler similar to a ramped barrel. I made the ramp extend all the way into the magazine so that the front of the magazines had to all be relieved to fit around the new ramp. I have not have one single missfeed since and its a nice shooter now. Thankfully I was careful enough when welding that the beautiful bluing was unaffected too.
 
Had one of the first .45 AMT Hardballers that came out in the 70s. It would roubtinely freeze solid in half battery every 3 to 5 rounds.
 
My tip-up Beretta .22 would jam with really cheap crappy ammo. CCI minimags? No problem at all

Glad you got it running, but why not cut out the frame ramp and install a ramped barrel?
