Picked up the GP100 in 4" this afternoon... I compared it against the 686 Plus (the store didn't have the 66 or 69 models). I like the feel of the trigger in the Ruger better. Its' smoother in double action and crisper (at least between the two I had to compare).
I plan to bring it to the range tomorrow afternoon (before dinner) to feed it some ammo. I picked up a box of 38 special as well as a box of 357 Mag to try out. Once I feed it some ammo, I'll decide if I need to do anything more to the trigger. It's highly likely I'll get the lighter springs for the action as mentioned earlier. Just need to make sure it's something I'm comfortable replacing. I have no issues working on my AR rifles and doing a fair bit to my 1911's. So as long as I can't
**** it up, I'll probably do it.
BTW, the grip on the Ruger also feels better than the one on the S&W's I fondled... The GP100 was the last one they had in stock too.
