I just noticed on Dane Burn's thread, "The Best Damn Raffle Ever", there is a photo of a Richard Heinie 9X23 built on a Springfield Compact. He must have the shorter magazines for it. I will pursue this further and let you know what I find.
I, too, would like to find out about this. I have a Colt CCO and it is an outstanding carry piece, but I think one in 38 Super (a cartridge I am just getting into, but enjoying very much) or 9x23 would be awesome!
I received a reply form Richard Heinie on the Gunspot Forum. He is a moderator there. He said the Springfield 9X23 is a Commander, not a Compact. If I want .38 or 9mm magazines for a Compact, they must be cut down from full size magazines. There's our answer men. It's a custom job or nothing. I also have a C.C.O. that I would consider having converted to 9X23 as a backup to that full size 9X23 that I have been dreaming about all day. Although, a new slide, barrel and custom made magazines would really run up the price of converting the C.C.O. Ouch! Maybe "cost prohibitive". I hate those 2 words.
I found them on the Metalform web page. Also, if you take the metalform std size 38 super mags with the removable base plates, remove the base plate and replace it with the Wilson base plate that converts their std mags to officer use, you have carry mags with increased capacity. The Wilson base plate hole need to be enlarged and a little counter sunk to allow the Metalform base holder to fit the Wilson hole.
