Hey all thanks for the replies. I started entertaining the idea of making my own spring because I still have the very first semi auto pistol I owned and it’s a little old, imported, Italian, obscure. I’ve already replaced the firing pin and triggger spring once years ago. Numrich’s parts were already slim then, and by now have dried up for most consumable parts . So no parts availability. I hate the idea of a whole pistol being useless because a tiny little spring being unavailable. So I dont shoot it anymore because I know I’m up the creek unless I can make extractors and springs. And there’s something about the principle behind being able to make a vital piece of the firearm.
