 Like in Limited, double stack handguns can have a magazine length of 141.25 mm and single stack handguns (i.e.the 1911) can be used with 171.25 mm magazines.However double-stack pistols like the 2011 seem to be preferred over single stack models due to easier mag changes, and single stack handguns are therefore naturally more competitive in the Single Stack Division where they compete against other single stack handguns.
