I have one, easily my most respected compact pistol I own. I replaced the recoil spring after about 1000rds with a SigSauer Orange sport spring after the slide seemed to slap a bit, and it's been flawless ever since. I have put north of 6000 rounds through it and I haven't had a single issue. I changed out the grips for Hogue Rubbers, but have an assortment based on my moods, everything has always fit. Added a few more mags to it (NP58 work great) and I polished the slide to a nice rugged worn look after a sonic cleaning screw-up took the bluing off a few thousand rounds ago.
This was the first handgun I have owned and have since added over a dozen to the litter, but this is the first gun I shoot at the range and the last gun I put back in the case prior to going home. I have many nicer pistols from a variety of manufacturers including Sig, H&K, Desert Eagle, Ruger, Colt, and so on, but I really have a soft spot for this gun. I shoot incredible groups with it, have never had a click no bang other than when I sat a primer in backwards, and love to tinker with it. I will never sell it. This is the one pistol in my bedside safe.
