My AMT is an older one. The guide rod is not rough. It did not come mirror polished, but I did polish the slide flats myself to a mirror finish. The two biggest problems was the original recoil spring was weak and the feed ramp needed to be polished. It will reliably feed ball ammo and even hollow-point defensive loads. Keep it clean and it mine functions reliably.
I don't carry it as much, however. It's easier for me to carry my Ruger LC9....but the LC9 doesn't have the stopping power of a .45acp. Maybe Ruger can make an LC45???
