“Same with the almost identical Ruger GP-100”
I have three .357’d.
Blackhawk from 1972.
GP-100 and SP-101 from about 1995.
Found GP-100 at gun store, pre-owned but never fired.
My 6” GP 100’s a great gun. It’s a tank! Out of all the .357’s I have that one’s a pleasure to shoot.
out of the box the trigger is a bit heavy but a new lighter trigger spring is about $10 and very easy to swap out. Once I did that I liked my GP-100 even better than the SW 686. They feel so solid and manly in your hand.
