Well, I finally got to work on it today. It works like a charm. I have to admit assembly was not an easy task. Took me more than a few tries to get the trigger assemble to work. Were I to do this often, proper sized slave pins would be the way to go. I was wondering how it would shoot because that 21# spring is very stiff compared to the stock unit. All shots fired went off without a hitch and I was shooting Winchester white and UMC yellow box ammo. The +P JHP's should give no problems. Have to run now, just wanted to let you all know and to thank everyone for their help. Now I have a 444 to look at that my son-in-law got cheap. He said the mag tube moves under recoil and causes feeding problems. But that's for the 444 board...talk to you later.
