Ordered a hammer off of E-Bay and installed in my Model 37 Nickle. The installation was quick, easy, and did not have to change any parts, ie, sear. I bought it with a bobbed hammer, someone did a horrible job with it. I paid a little to much for the new hammer but they are getting hard to find. Anyway here is a couple pictures or before and after.
Good show, pal, now it looks the way it's supposed to. Are you able to control the 37 with those grips? That style slips in my hand under recoil. Heavier, too.
