Adequate with Fitting

Having bought & used both blued and stainless kits, I recommend the stainless kit. The mainspring cap retaining pins in the blued kits required turning down with drill & sandpaper to fit Springfield, Tisas, and Wilson Combat mainspring housings. The kit's supplied "23 lbs" mainsprings were long and required very heavy compression. Hammer & trigger operation were notably stiffer, but usable. I am replacing the kit springs with Wolff 20 lbs rated mainsprings

No housing pin. But good kit otherwise.

No housing pin. But good kit otherwise. I mean it showed clearly it did not come with it so I can't really complain. Everything it comes with works well. I just lost my pin the other day so if it had been included ;).
