Can I change my 8-round Makarov to accept high-capacity 10- and 12-round magazines?
No. The 10- and 12-round magazines are wider and can only be accepted by the Russian commercial IJ-70-18AH and 17AH (or similar) wide-grip Makarovs. Short of altering the frame, there is no way to use these magazines in standard 8-round Makarovs. We found a stash of the +2 magazine extenders for 8-round magazines with the folks who make the Pearce grips. We had a chance to test them, and we came up with a solution to both problems of the magazine release and the mag spring power. These are now sold out and not available any longer.
