OK...I love my PMR-30 despite it's many quirks...
I've had my buffer melt after about 1000 rounds, I've had my assembly pin break in half after about 1500 rounds, and I've had my front sight fly off after about 1800 rounds.
No worries, Kel-Tec customer service has been great throughout.
The PMR is just so much fun to shoot, I don't mind dealing with these hiccups.
However, the primary problem that I have at the range is failure to feed. I've had the best success with CCI 40 gr cheapo stuff from Wal-Mart (both FMJ & JHP). The Hornaday Critical Defense were horrible (FTF, FTE out the wazooo). The Speer Gold Dots were better, but still a few more FTF than the cheap CCI stuff.
Again, despite my problems with the Hornaday, the main problem that I'm having is failure to feed. I've read about the "limp wristing" stuff and made a concerted effort during my last range trip to keep my wrist stiff. If anything, my results with the Gold Dots was worse.
I do my best to be very careful when loading the magazines to make sure that the rounds are set properly.
I have noticed that my feed ramp is a little rough. Far from the almost mirror smooth finish on my other pistols. But, since the ramp is polymer, I've been hesitant to try to polish it.
Has anyone seen improved reliability after polishing their ramp?
Does anyone have any suggestions about how to polish the ramp without damaging the polymer?
Pictures of the ramp are attached.
It, perhaps doesn't come across well in pictures, but that raised dot in the middle of the ramp is raised up from the rest of the surface. I can feel it with my finger and can catch my fingernail on it if I run it up the ramp.
