If a 9SC holds 10 rounds (15-hicap) and a 40SC holds 9 (12-hicap) would the 45 GAP hold 6 or 7 (9- hicap)? I would think 6 would be a minimum if they ever do make one. The Glock 39 holds 6 in a shorter handle so 7 may be possible.
The largest capacity subcompact magazine.....a 9rnd 40 mag will fit 6 45 gap rounds easily. Plus the one in the chamber and the xd will match the Glock 39 with its total capacity. Then if you use a grip filler and a full size magazine it will use the same magazines as the 4 and 5 inch xds it would hold 9rnds. And the 6 plus one capacity of the xd sub would also match the capacity of the micro compact 1911`s.
