Actually.. With the exception of the select-fire gas pistols (Ie. Beretta 93R and the KSC Glock 18c/26C/23F, TM G18C etc.) I don't think many gas guns have 'hicaps' per say. You're going to have to deal with small magazines (ie, sub 25~ rounds) for almost all regular pistols (exceptions being the KSC Glock series where you can shove the large high-capacity mag into the 26, which looks funny )
