I had a Keltec PMR30 just like that straight out of the box brand new. It took 3 months at the factory to fix for something that should have NEVER left it
Dads crappy high point would always eject, but it was like the recoil spring would never exert enough pressure on the return stroke to strip and chamber the round. You could bop the slide forward with your other hand to make it work.
My parents had 44 guns in all, but never tried a keltec.
At the time I was ticked off that I had to wait a year and a half to get my Keltec PMR30 but in reality I was lucky. By the time I got mine the bugs had been worked out of it. I’ve had zero problems with it. But I do pretty much only run CCI Maxi mag through it.
