Update - rebound spring swap and first range trip.
Ok, I thought long and hard about just leaving the trigger alone but got bored and thought I'd swap out the rebound spring. Figured if I changed my mind I could put the original spring back in.
I dropped a 13# Wolff rebound spring in it and the trigger pull is noticeably lighter and the trigger return is still crisp and strong. While dropping the spring in I noticed the rebound slide and the sides of the hammer had been polished when this thing was put together at the Performance Center. I felt no need to screw with anything while I was in there and simply swapped out the rebound spring, lubed the contact points, and reassembled. The trigger now feels like I thought it should have felt straight from the Performance Center.
Took it to the range Friday and put the first hundred rounds through it. Took a few cylinders for me to get a feel for it as I don't shoot revolvers much these days but overall I'm pretty happy with it.
Trying to be realistic about the intended purpose of the j-frame, I set up two targets and did the majority of my shooting from about five to ten yards transitioning between the two targets. While I did several different drills, most of them involved drawing the revolver, engaging one target with two round, engaging the second target with two rounds, and re-engaging the first target with the last round all while moving backwards away from the targets.
Here is the first cylinder I put through it. I wasn't setting any new land speed records but was taking about two shots every second or so- basically "double tapping" each target. Two shots on first target center mass, two shots center mass on second target, and then re-engaged the first target with a head shot. Pulled my shots on the second target a little left from the transition.
Ignore all of the pasters in the next photos. I spent a little time messing around with my little NAA mini revolver and didn't have the best of luck with that thing.
Got better as I got more of a feel for the 442 and was keeping my shots centered better by the end of the day.
The last couple of cylinders I pretty much dumped about as fast as I could while retreating from five yards. I think I only see nine holes in the target but there's no way I totally missed the target so two of them must have pretty much gone through the same hole or something.
I likely could have made much smaller, more well centered groups if I took my time and slowed down or if I stayed stationary and wasn't moving back but I bought this to carry, not shoot tiny groups.
Overall, I'm pretty happy with it. For a carry piece it should do the job if I can keep a level head.
