Bizarre problem with firing new Kahr PM45

[Cimmerian]

Got my new PM45. Went to the range to fire the obligatory 200 rounds.

Got through a mag or two when the bizarre happened (this has never happened to me, anyone?). Suddenly the normal trigger pull did not discharge the weapon, I pulled further (pointing down range!) nothing. Finally it had no movement to it at all, and I squeezed very tightly against the solid unmoving trigger, and got the weapon to discharge.

This freaked me out a bit so I stripped it down, cleaned it thoroughly, made triple-sure everything lined up, then tried it all again.

BTW, I don't know if this is important, but I had a lot of trouble getting the barrel out. It kept hitting the piece of metal the recoil spring guide rod goes in front of. Have a Kahr PM9 and never had any similar issue.

I got through a few mags ok, I thought I fixed it, but then it happened again (and a few more times as I experimented some more as explained below).

I am pretty sure this is a trigger/firing problem as

a) It feels that way
b) I did try an assortment of mags and ammo and it eventually (or quickly) happened with each

Any thoughts?

Have you guys seen this or something like it before?

If not, any speculation?

If so, what to do?

Thanks!

Sounds trigger bar related. When you took it apart and put it back together did it work and then mess up again or did that help?

Might take the slide off and check the trigger bar to see if there's any polymer shavings etc impeding it's travel. See if it's moving back and forth easily without the slide.

As bawanna says, look closely inside for debris, must be something in there (polymer, brass, etc.) you`ll need a good magnifying glass and light (probably). As for the barrel, hold the slide upside down, muzzle away from you, lift out till it hits that bar, rotate about 90 degrees clockwise, it should clear.:cool: works w` my pm45.

On the barrel part, I wonder if the notch is missing on the little piece of metal inside the slide between the barrel opening and the recoil spring opening?

I will try all this weekend, if I fail, back to Kahr!

Thanks everyone.
