I'm in a quandary.....but I think the correct way to handle it, would be to replace the mainspring. I recently bought a 1920 Commercial 7.65 which is in excellent + condition, but has a very stiff mainspring. My normal reloads, and including some factory Fiocchi ammo, won't cycle at all; the breech comes back and cocks, but then slams the fired case back into the chamber. I'm guessing that someone put a 9mm spring in it. I really don't want to load-up hotter ammo. Your comments will be much appreciated.
