[QUOTE="Buzzdraw, post: 913956, member: 385"] Stock kit frames have the .45 spec ramp. A 9mm/38 style frame ramp is different from a .45 ramp. Grab a 9mm Colt frame and a .45 frame; its pretty obvious. The .45 ramp has less metal on either side of it than does a 9mm. I doubt if you will be able to get your gun 100% dependable by removing metal, since you actually need more metal in the feed ramp area to work with, not less. Don't try to remove metal forward (toward the dust cover) in the effort to create a 9mm frame ramp; you will certainly cause feeding issues. These issues will require either frame ramp weld-up or going to a bridge cut for a ramped barrel. Most everyone doing a 9mm buildup on a high-cap frame will bridge cut the frame, then install a Nowlin-Wilson or Para style ramped barrel. Personally I prefer the Nowlin-Wilson because of its greater bearing area on the frame. Once you get the barrel fit hurdle passed, you get to tune the mags. Hi-cap mags for 1911's generally do not run dependably out of the wrap. Sorry to be the bearer of possibly troubling news, but truth is better than sugar-coating. [/QUOTE]
