Post #5 by T.M. Nichols. Lots of truth in that. I never saw much future in buying a pistol just to purge its components to upgrade to machined steel name quality components, .ie. investing $450 in parts in a $400 pistol. Some of that defeats the skill building goal. If you are looking at such a product and the slide, frame, and barrel really are that good, then chances are some of the smaller parts are quite useable. For a project like this buying the pistol to upgrade, I suggest shooting it. Not a box of ammo...a couple hundred rounds, get to know it. Then establish what needs to be done to make it do what you want and to do the things you like about it better. Set goals for a noticable upgrade with least amount of parts purchases. I did that with the two Rugers I bought and both are nice pistols as they are.
Mind you, some of the parameters and features you desire may be perceived rather beneficial. Example, on a GI pattern gun, I now shape the A1 grip safety so I get a higher good hold and bob the hammer a lttle to eliminate hammer bite. 200 comfortable rounds of ball in a shooting session just leaves me hungry for more shooting. I am not suggesting you mock what I do. Just use an approach which would allow to realize more of what you are seeking. Let the pistol be what it is...just better.
I have looked at those SDS pistols with the wide spur hammer in display cases. Haven’t handled one...yet. Tempted to pull the trigger on one and refine it if I can strip it first. But for similar money, I can get a known quality Springer Mil Spec Defender and have same practical end product which I might be able to make a few $$ on if I decide to part with it.
