I was wandering the difference between the G21 & G21 FS I have shot a 21 it accurate a little big (brothers DUTY gun) but it's not a SF TIA
Glock 21sf is 3 millimeters shorter in grip circumference front strap to backstrap. Some have the dual mag release, some don't. Some have the picatinny rail, others have the standard glock rail.
The older glock 21 mags will not work in the 21sf, the 21sf mags will work in either. Other than that, they are the same gun.
