I picked up a Kel-Tec PMR 30 this week. Given that I don’t live in griz country anymore, my main interest is a light trail gun and plinker. For those of you who have these and particularly those who put high round counts through them, what issues have popped up for you? Just looking at it, my first thought was I should probably loctite or paint pen the safety screws. Are there any maintenance issues that you have had with these things?
