Hmmm, I guess I don't know what a Ruger KGP-141 is. I'll look it up. But, I do have a S&W 686 2-1/2" and 4" and they do what they're supposed to.
I took them to Gunsite's Advance Tactics Pistol class and didn't have a single problem with them.
The 686's and I assume the Ruger is similar, are pretty big but not too big to CCW, at least not for me.
Just took a quick look at the Ruger KGP-141. Looks like a 686. I like the Ruger cylinder release better for some reason.
