So the PMR-30 has been out for a while now and they even made a rifle version and a 22LR version of the pistol. I have had mine for about 2 years now and it has been shooting just fine without any problems. My question is this, how long will the feed lips last on these plastic mags? I recall many many years ago there were problems with the plastic aftermarket magazines for the 10/22's, the feed lips were wearing out, chipping and failing to function. The fix was the metal lips and the problem pretty much went away, so how long will these last before they start to fail, get brittle and start breaking off? I'm sure the plastic is better than the 80's/90's plastic but it is still plastic/polymer. Is the aftermarket going to make metal mags for these?
