Everything on it is bone stock except the grips. It took me awhile to get those right. Taurus increased the diameter of the grip screws for the better but I was too chicken to try to increase the counter bored screw holes without a reamer and guide. Screws are also cheaper than those grips.
I still love my daughter in law’s reaction when she say it. She said, “Where did that one come from”? She shot it slightly better than my kid’s Ed Brown but that was probably because his is Commander length and I think she was able to take advantage of the longer sight radius.
Those Heinie sights don’t have painted dots. There are plastic inserts that are pushed in from the bottom of both sights. Pretty neat idea.
