I'd sell at least one Mak, the CZ, &Norinco
and get an alloy frame from Spld, and a (used, $400) Colt .22 unit, but I"d be sure to testfire it before buyiing. In any case, get the adjustable sighted version, because sighting in a fixed sight version, especially one with aluminum sights, is a pain in the neck. The steel slide of the Colt unit, and its floating chamber, increases the recoil effect and so does the use of the alloy frame. The 2, put together, mean that the .22 bounces about like a full sized, steel framed 22. If you put a 9mm Commander slide group on the alloy frame, it recoils just like a full size and wt 1911 .45 does. So why spend 12c per shot, instead of 2c, and why spend 22c per shot for .45 practice, when you can spend 12c a shot (for Win white box 9mm, at wallyworld)?
I've altered many a .22 unit mag to feed hp's reliably. What I do is mix up some JB weld epoxy, use it to build up the top of the mag follower about 1/16" in the rear, 3/32" in the front. This causes the .22 rd to hit the feed ramp at a higher angle, and then it feeds hp's just fine.
