What sort of group size do you get at 10 yards with a S&W J-Frame, 1-7/8" barrel ?
The CCW qualification in CA sucks. I suppose it wouldn't be that much of an issue if I didn't want to have a NAA Mini revolver on my permit...Well some folks sure seem to do better than I do. I've been practicing a year now and have not gotten measurably smaller grouping at 10 yards. I still have about a 7" group with an occasional flyer out at 10-12". This is aimed slow fire, not rapid fire, or from the hip/point shooting. I have my California qualification shooting for each of my CCW handguns in a couple weeks and this little J-Frame is the only one of the three that gives me grief.
Intense. Please do remember. Pictures are priceless.I did the work myself. The curse/benefit of being a gunsmith. I machined off the front ramp and cut in a dovetail .060" deep and installed a Novak blank (the rib on the barrel is just about .125" wide, so it was about right). I took a .125" ball end mill and opened up the rear sight channel a bit (mostly for width, rather than depth). I filed the blank at the range until point of aim was regulated with point of impact for the loads I wanted to use. I marked the left/right orientation of the front sight, pulled it and installed a .125" gold bead from SDM (more of a dome profile than some of the other options out there). I removed the gold bead, tinned the parts, applied heat stop paste liberally, and silver soldered the front sight on. I then machined the sides of the dovetail even with the barrel rib. I had some other work I did also, sent it to be cerakoted and epoxied the gold bead back in. Voila.
Its a long, drawn out process, but when I don't have to pay for labor, it makes it easier. If I had to send it to another gunsmith, I don't know that I would have done it. I wasn't paying attention to the labor and time since it was my own toy. I just buried it in amongst other projects when I had time. Probably a few hours of machining, plus test firing and regulating to ammo (about 20-30 rounds of JHP ammo, critical defense, I think), plus refinishing, plus parts. Parts were actually fairly cheap. $20 for the front sight, $25 for the gold bead, and other incidentals.
I have since been conned out of that particular revolver, but I have another one that I plan on doing the same thing to. If I remember, I will try to post before, during, and after photos.
