I have a 6 month old PM40. Lightly used. Shot fine and never jammed until I field stripped her and now it will shoot the first magazine and then when I reload the gun and pull back on the slide, it doesn't go forward. I can release the slide with the slide lock lever and it will chamber a round and I am able to fire. Then the slide locks back and you cannot pull it back to release it. Once again you can use the lever to release the slide lock and it will chamber the next round.
Very frustrating. I have had the gun apart several more times. I do not see anything wrong, but I am also not a Kahr expert.
Any help from the forum would be greatly appreciated....
