These have been discussed here previously. I own one -- I bought it for my wife when she said she wanted to learn to shoot, because I thought she would learn easier on a revolver ... then she decided she really DIDN'T want to learn to shoot, so the Armscor became mine. I like it a lot.
When mine came in at the shop, the guys behind the counter couldn't believe how nice the trigger was for a sub-$200 gun straight out of the box.
Mine is now wearing a set of square-butt wood grips from CDNN, for a Colt Detective Special. I don't recall if I had to do any fitting -- possibly a little bit. If so, it wasn't much and it wasn't difficult, or I wouldn't have bothered.
