I finally got one, earlier this week. I've only put 50rds through it so far, shooting off hand at a steel silhouette target at 15yds and a 3"x 20" steel cylinder at 35yds. After roughly adjusting the sights, I was able to keep all shots in the head portion of the silhouette and consistently hit the cylinder. I was using 40gr CCI mini mags.
I've got a couple of S&W 617's, 4" & 6" and an SP101 that I want to shoot, off the bench, along side the GP100, in a half assed accuracy comparison.
I picked up a spring kit for the GP today and will put it in before doing a comparison.
My initial impression of the gun is positive, I think it's going to be a keeper.
Sorry I couldn't be more help.
