I have a first generation model 17. I bought this gun in 1988 & have fired thousands of rounds through it. The only part I have had to replace is the slide stop spring ( my own fault, can't blame the gun).
Mods include, Scherer 3.5lb connector, .25 trigger job, 4lb striker spring & Hogue slip on rubber grip.
This is one of my favorite guns. :grin:
