Default Why do 45acp handguns jam on the last round most of the time when they jam?

Well my hk usp 45 compact finally jammed on me the other day. I was a little surprised but I figured it was about time after literally thousands of rounds. It failed to feed on the last round in the mag. This got me to thinking and I had a shocking revelation (not really but it sounds good), of the 45's I own all the malfunctions I could think of were the last round in the mag. Now I know it's definitely time for new springs and followers in my hk's mags as well a a new spring for my rsa, but other malfunctions with other 45's have happen with springs almost brand new. So my question is why are 45's more prone to ftfeed on the last round in the mag than other calibers?


Never enough guns or ammo

My CZ 97B 45ACP has never jammed, and I have put thousands of rounds through it taking tactical pistol courses.

Maybe you just bought the wrong 45ACP?!

After a few thousand through my Kimber never had a fail to feed, or eject for that matter (never even loaded the factory mags ) have only used CM power mags.

My xds has had no issues either with just over 2500 through it. ( I did have failure to extract with Tulammo though, case actually was stuck in chamber)

Two things come into play here:
#1 Mag spring tired. Last round not pushing up fast enough to be in position when the slide is closing

#2 Last round, gun is lighter (and you are more tired from shooting). Operator induced malfunction because the light gun in a tired hand recoils a bit more and the slide may not cycle correctly on the second to the last round, leading to the FTF on the last round.

Replace the springs and hang on to it.

This is certainly NOT a "problem" with .45 ACP pistols. It just is.

Sounds like limp wrist. More of a control issue.

But "limp wrist" has such a negative connotation

Could also be a cleaning issue. Many people don't realize that mags should be disassembled and cleaned now and then. I like to lube my followers with graphite.

Mag problem. Nothing else.
Bad Follower.
Weak Spring

A proper grip is important, but shouldn't crop up only on the last round.
When I had extractor problems, it happened on full, half and last round. No preference for last round.

If you truly can duplicate it with every magazine, then perhaps, the gizmo that catches the slide lock is frizzled. A frizzled gizmo is something to avoid.

Better than jamming on the first
