In re-assembling my aluminum framed 1911a1 clone pistol I inadvertantly broke off the left corner pin hole area that holds the mainspring retaining pin. There is enough to hold the pin but the lower 1/3 section of the pin hole is missing. I'm thinking of reinforcing this with a thin plate that will fit over the grip screw holes & extend down over the pin hole & using a longer retainer pin. -----Or making a special pair of grips that doesn't have the cut-away for the access & re-enforcing the pin hole thru the grip on both grips with a metal bushing thru the wood & again with a longer pin use this as a fix for the damanged grip area. If I have described this plain enough for you to picture what I am thinking, what is an opinion of the repair? Comments please-- sloejoe I'm sorry I forgot to mention this is in .45acp caliber.
