Ruger SP101 Hammer spring stuff

[Runningman]

A number of years ago bought a Ruger SP101. The DA trigger pull was really bad. It almost felt like it was binding up near the end of travel. It was so bad I didn't shoot it much and it more or less ended up in the back of the safe for years.

Recently I ordered a Wolff 12 LB hammer spring. Stock is 14 LB. I lightly stoned all the edges of the hammer spring strut with the hammer spring off. I installed the 12 LB hammer spring and used some Moly grease on the hammer strut pivot point.

The results was a much noticeable improvement in trigger pull especially DA.

Took it to the range last weekend to fire 70 rounds of handloads using the harder CCI 550 primers to check reliability. Worked good, wished I had done this sooner its like a different pistol.

Hammer strut roughness is cause of a lot grief in these. As you note polishing the strut makes an improvement. Going through the rest of the action makes it even nicer. Have one with the 8 lb trigger return spring and 10 lb mainspring in and it fires all that I run through it. Double action went from 14 lbs to around 9 lbs with this setup. The IBOK book shows what all to do to them. They are available over at RugerForum.net from Iowegan (but he is out and will have some more printed up in the Fall). Like the action a lot better than a Colt Magnum Carry I had (as I duck the flying material).
