New Member - PM45 failure to feed

[DKD]

A slightly different problem

I have firmed my new PM45 several times and now passed the 300 rounds count. No problems to feed or extract in the past 150 rounds.
Now comes the puzzling occurance....with FMJ range ammo this weekend the gun would not chamber when loading with the preffered method, using the slide stop....just hangs up on the bottom of the feed ramp. It doesn't do it when I rack manually or when the gun is firing live ammo.
Could it just be the magazines? The feed ramp is mirror bright. Very strange, not hat it barthers me I prefer to hand rack the slide.

Check to make sure the rounds are pushed all the way back in the mag. I tap my mags. in the palm of my hand to make sure all rounds are to the back. I learned that little trick from this site, can't say who from I've read too many posts to remember who said it.

Did this just start and the ammo is something that you haven't been shooting?

Lock the slide back and slowly insert a FULL magazine, watching to see if the nose of the top round touches the slide lock on the left. Another thing to watch for, is whether the "stripper" part of the slide is sitting behind the cartridge. Mine had this problem from the first magazine loaded, but I didn't know what to look for. The "stripper" was resting on top of the cartridge base/rim, so that when the slide was released, the stripper rode over the cartridge, resulting in an empty chamber or the slide stuck halfway there.
The fix for that was beveling that lower front part of the "stripper" so that it pushed the cartridge AND the magazine forward and wound up behind the cartridge.
I wouldn't think that you have this problem since you didn't initially have any problem.
The work around for that was hand racking all the way to the rear which got the stripper behind the cartridge.
You could check the feed ramp for burrs and polish it some more... can't hurt. And check that the "stripper" is beveled... or beveled enough.
Good luck and good shooting.

Range Update

Now it's been a few times to the range and about 250 rounds through the recently-returned PM45.

There were 3 or 4 times that the slide locked back unexpectedly. But I think I figured out the reason. I think Bawanna and jocko got it right.

Once or twice it locked back when I was just being lazy with the grip and not paying attention (late in a session). Another time it locked back, but I am not sure why it happened, but likely due to a bad grip.

One additional time I rested my thumb NEAR the slide lock release as I wanted to see if I could make it happen. Sure enough it happened.

A simple change in thumb position and the pistol runs like a champ.

Now I'll clean it and try not to bend the spring!

Thanks for everyone's help.

Now to look for a good holster. Any suggestions on an outside the belt holster for a PM45?

I have had the same issues with my PM45 which I also attribute to user error. I use a Mitch Rosen belt slide purchased from kahrshop. The setup works very well for all day carry.
