 While Standard handguns must fit inside the IPSC box with any of its magazines inserted, there is no box for Limited division and instead there is a restriction on magazine length of 141.25 mm for double stack magazines (5.561 inches, which is often incorrectly referred to as 140 mm magazines) or 171.25 mm for single stack magazines (6.742 inches) (often incorrectly referred to as 170 mm magazines).The maximum magazine length in Limited was changed from 140 and 170 mm to 141.25 and 171.25 mm respectively by USPSA somewhere between 2004 and 2009.On the other hand, if for instance a 2011 pattern pistol is used in the Standard division, either 124 or 126 mm magazines will usually give the maximum capacity and still fit the box.
