Fits or can be made to fit Colt "ACE" .22LR 1911 Conversion Units.
Original Colt "ACE" .22LR 1911 Conversion Unit magazines are no longer made and extremely expensive when/of they can be found on the used parts market. The magazine featured in this ad will fit some 1911 frames with ACE units or can be made to fit others by elongating the magazine's locking notch by (tediously) removing material from the top of the notch. The unaltered notch measures 0.128" high. It would not lock into my ACE with the slide forward until the notch was enlarged to 0.143". It now fits and feeds and functions perfectly.
