Mine is a 1999 vintage. still have it, I have shot anything and everything on sale through it. Probably well in excess of 7000 rds. I have had only two malfunctions and it was directly related to ammo. (loosely seated bullets) Every off brand, name brand of ammo through it. I have used strictly
Ruger 10 round magazines and one aftermarket pro something. Never had a pin walk out, did have to touch up the glow in the dark rear sight a couple of times over the years due to cheap dirty ammo. Never a problem with steel cased, or aluminum cased ammo. it just shoots and shoots great. No repairs other than the touch up paint.
