i own a 6" stainless steel gp-100 full underlug and its a pretty sweet thing. no real problems with it and with a 2 thousand dryfires and some replacement springs from wolff
www.gunsprings.com the springs a tremedous help in dropping the trigger pull. i put in the lightest springs from the gp-100 shooters pack and now i have a SA trigger pull of 3lbs and a DA of 6. now thats nice. they arent hard to install either. did it the second time i took the gun apart.
