My Commamder .45 was working fine until I put a Wilson #20 spring and full lenght guide rod in.I had several jams that were all the same. The rounds in the mag would nose dive into the mag and the rear of the cartridge would rest in the breech face. Pulling back on the slide would allow the cartridge to pop up and be chambered. It seems the slide was moving too fast on its return and hitting the rear of the cartridge and pushing the bullet into the magazine. This happened to 3 out of 5 mags. Should I use a Wilson #18.5. Is that the factory weight? I went to the #20 spring to lessen the shock to the frame of the aluminum Commander.
Will the #20 spring work if I use HD mag springs?
