Since last posting, I've gotten a set of checkered Altamont Super Walnut grips to help with the recoil and worked on my front sight focus and trigger squeeze. I had the day off yesterday, so I checked out a recently-opened range and popped a few caps.
I had ammunition from 3 different manufacturers; Winchester white-box, Federal American Eagles, and Magtech blue box, all these were 230 grain. The bullseye targets were (I'm guessing based on how many cinderblocks down the wall I sent the target carrier) about 20-25 feet, and the silhouettes were in the 15-foot range. All of these, except for one of the "dirty bird" targets (top left bullseye), were fired with double action only. The silhouette targets were the last I shot, each had 12 shots fired at them.
When I do my job correctly, the sights work well. I seem to be either tightening my grip as I fire, using too much trigger finger, or dropping my head just as I fire. Or it's some combination of all three. I felt as the Winchesters and Magtechs were slightly better for me, so I went through what I had left of the Federals just to have some reloading brass for later.
I have a lot of practice to go, I know. I'm still not keen on this plain half-moon sight, it's the one thing I haven't been able to modify/replace yet. However, I have new confidence in this revolver and in my experience confidence in the equipment counts; not as much as practice, but now I in no way feel like I have a lemon of a revolver.
