I have a blue 4" fixed sight model. It won't shoot to POI (about 10" low at 25 yards). The trigger is lousy (long, heavy, gritty, with hitches throughout). It is very roughly finished - edges on the trigger and hammer spur were sharp enough to cut my fingers. I had to do a bunch of polishing to take the edges off.

Took it to a smith for a trigger job to smooth it out. That helped a little, but it's still no 686. I put in a lighter mainspring, now it won't fire CCI primers.

The GP 100 is praised for being built like a tank, but how relevant is that? So is a 686.

I don't plan on selling it, but had I known better I never would have bought it.
