FN FNS40, been one of the best pistols I ever carried. My wife carries it now and I carry my old reliable Glock 21 Gen 3. Neither have ever had a single problem and I trust both with my life and my family's...
I have 2 AR's, both home builds on Young Manufacturing lowers with everything else pretty standard Colt mil-spec parts, BCG, etc. One has a SDM-R barrel and KAC M5. The other has a Expo Arms 11.5 CL barrel. I've put them through hell neither have failed me.
I trust my Stag 10 in 308 the same. Another home build, SP10 barrel, JP bolt, I've never had a single issue with it from shot #1. But I put a lot of time and research into it before I ever shot it and always checked every little fastener on it after every trip.
Mossberg 590A1 that was the first shotgun I ever owned. It's still bone stock.
