1911 feed ramp sanding jig

thingiverse

This is a simple jig for sanding the feed ramp on a 1911 pistol to 31.5°. To use the jig, slide some 1/4" rod through the magwell so that it rests against the mainspring housing edge of the magwell, with the narrowest part of the jig on the feed ramp. Wrap the jig in sandpaper and sand away. Look at the cutaway pictures to make sure that you have the orientation right while sanding. Make sure that you DO NOT radius the top corner of the ramp, it must be a sharp corner for proper feeding. I shouldn't have to say this but DO NOT REMOVE ANY METAL FROM YOUR GUN UNLESS YOU KNOW WHAT YOU ARE DOING. Metal is easy to remove and hard to put back on. Oversanding the ramp can cause your gun to jam and become unreliable, and it will need to be repaired by a professional gunsmith.
