This is slightly smaller than the SIG 226 ST but feels very similar apart from being marginally lighter. It serves well as a platform for IDPA shooting where it represents something very close to use of the 226 without having to use that always for carry gun practice. The manual of arms is shared with the 226 and 220 - being DA/SA and de-cocker and very safe for carry. An excellent carry platform option.
While the 226 cannot accept 228 mag's the reverse is fine and so this gun can easily run on a 15 (or even 20) round 226 magazine. It shares commonality with the other two SIG's by also having Crimson Trace grips. These give a better feel than factory as well as providing an easily seen dot when light is reasonably below maximum.
