1. The main pin in the D.W. Bomar ripoff broke 3 or 4 times, even when replaced with a hardened steel drill bit. I finally took an oversized titanium drill bit, turned it down until it just barely would fit, and smashed it in there with a punch. I attribute this problem partially to the high front sight height, which required the rear to be adjusted high, which I believe put more flex on that pin every time the slide cycled. Ultimately, DW sent me a lower replacement front sight for free, and I had a local gunsmith machine it down to remove the recessed white "dot", and I replaced the rear DW Bomar ripoff with a real Bomar. Absolutely no problems with the sights since then.
2. The pistol developed some FTE problems and ultimately I chipped the extractor claw extracting stuck cases. This was traced to gunk in the extractor channel after approx 3000 rounds. I got a free replacement extractor and spring from DW. While installing it, I made sure to stone the top and bottom surfaces to ensure no burrs and more clearance. I've run that extractor for the last over 7000 rounds without cleaning the channel and no problems.
The parts are all original except for the sights and trigger bow/shoe, which I replaced because I prefer a short trigger. The same guy replace the trigger, recut the sear angles for the trigger job, and removed some sharp edges on the frame where the beavertail mates.
This was my primary IPSC & 3Gun pistol for about 18 months, and runs real good.
