Good day sirs. I recently joined the 1911 fad when i bought my first 1911 in a commander model last gunshow. Last time i posted, i asked for some inputs on what are the 3 must have basic mods for this gun, and to sum it up; most replies includes the sights replacement, springs replacement(recoil 14lbs/hammer 19 lbs/extra power firing pin), and trigger job of about 4lbs. I followed all 3 suggestions and when it was finished, I test fired the gun for 20 rounds of reloads (with new brasses from a reputable source) and the gun performed without any malfunction. Okay pati recoil, sweet. As i've read and heard, my spring set ups requires it to be paired with a compatible ammo which is not too heavy to avoid slide cycling problems and excessive slide-frame battering. Can you please give me sirs the right ammunition specs and brands na pwede kong ma test with this spring set up? Thanks po.
