I posted that from my phone and meant to come and add some text, but I got sidetracked and now can't edit.
This is my (somewhat early) birthday present to myself. 629-4, combat hammer and combat trigger. I'm not sure if it was originally ordered that way or if they are later additions. It's been used as a bowling pin gun and the trigger has been lightened, particularly the single action. The downside is the hammer will push off at an estimated 12-15 lbs of pressure. I bought it today so haven't had a chance to fire it yet. I'm already in touch with my gun smith of choice to take a look at the guts and get the push off addressed.
On a side note, the fellow I bought it from works for a local federal prison and seems the squared away sort. I invited him to PF, so hopefully we'll have a new member shortly.
