I see a lot of problems with feeding that can be attributed directly to an improperly machined feedramp. When the feedramp is done correctly, there is NO need for elevated mag catches or special magazine designs that present the rds higher than original 1911 specs. Several of the 1911 clones, yes even those by the top of the line semi-custom shops, are crippled by shallow feedramps. A proper feedramp extends south of the top of the frame to a .420" depth and is cut at 31 to 31.5 degrees. The bottom of the feedramp should be just above the bottom of the slide stop lug cutout. I've seen guns done by big name shops that have feedramps only .280" deep. They will work with ball and sometimes with selected hollowpoints through selected magazines, but they still are not 'right'. I'll take pics of the next one to cross my bench, and of the process to correct the geometry. __________________ Chuck www.rogersprecision.com www.louderthanwords.us Slightly shallow original feedramp.
