I have a Glock 20 and a Springfield 1911 that I am going to be shooting light, match ammo out of for a qualification. When I first got the Glock, I was shooting Underwood Ammo and Double Tap. Both brands tend toward the "warm" side. I dropped a 24 lb recoil Spring in the Glock and the corresponding striker spring I guess to keep the striker from firing under inertial force. I loaded the 1911 with 45 Super so I did basically the same thing with it. Now that I'm shooting match ammo I'm going back to the factory recoil springs; in the Glock 20 it's a 17 lb recoil spring, in the Springfield it's a 16 lb recoil spring. Do I need to lighten the striker/firing pin spring in each? It doesn't seem logical that I should. The striker works fine in the Glock with the heavier striker spring, and the inertial force will be less with the lighter recoil spring. Same with the 1911. What am I missing?
