An update on my two 357 revolvers.
I put a stronger mainspring in the Blackhawk. Gunsmith had put a 17 lb. one in when he did the trigger job, it felt really wimpy and while it set off all the .357 ammo I tried, it didn't set off some of the 9mm. So I swapped the spring with a 19 lb. one.
The heavier mainspring (hammer spring ) actually dropped the trigger pull from 3 1/4 pounds down to 3 lbs. even. Go figure.
I put a white outline blade in the rear sight, a much easier process than switching out the blade in the S&W.
I still want to install a yellow insert in the front ramp, but for now I'm making do with yellow Testors paint.
I wanted to chamfer the chambers in the Blackhawk, as they are really sharp edged and you have to wiggle the rounds to get them to go in.
But the 5/8" cutter I had was too big for the Blackhawk cylinder, I have a 1/2" cutter on it's way from Brownell's.
I put the black plastic grips back in the box and ordered some new ones.
The plastic ones were grippy enough, but felt way too small for the chunky Blackhawk.
(Too short). My hands aren't that big, but I wanted a place for my little finger so it wasn't curled around the bottom.
So I got a pair of "extended" grips from Texas grips, they are 1/2" longer and cover the bottom of the grip frame.
They are Mesquite, with Ruger medallions.
The Ruger was shooting pretty good the last time out, most groups at 25 yards were around 2 inches.

The Smith and Wesson got a red ramp front and white outline rear. My old eyes can see those better than the target set up it came with.
The cylinder was sticking a bit upon opening, some research on the S&W forum helped me determine the center pin was too short. I ordered a new center pin from Brownell's, it was longer than the old one, and now the cylinder opens without sticking.
While I had the cylinder apart I put a slight chamfer on the chambers, then a good cleaning and lube before reassembly.
I sold the big bottom Target grips ( sorry but I hate those, always have) and have been using a pair of Hogue rubber grips (only $20).
Today I got some Hogue Rosewood grips in the mail. I like dark wood grips on stainless guns.
The rubber grips were a bit long front to back, but these wood ones feel great.
The S&W was easier to load, it didn't need much chamfer, the Ruger does for sure.
The 125 grain plated bullet by HSM shoots great with anywhere from 5.6 to 7.2 grains of Universal. The Smith had several groups close to 1 inch. 7.2 grs. was a bit more 'blasty", so I settled on 6.5 and loaded up 300 of them.
Velocity at 6.5 grs. is 1050 fps.

I'd love to get out and shoot some more, but we're having a week straight of rain, so an indoor pic will have to do:
