| Putting a full picatinny rail underneath the gun? I mean I know most all of them come with the light rail but this was a full picatinny rail with multiple slots. Is this new? |
| It's just the G21SF. Rumor has it Glock made a bunch with the hopes of a military contract and since it never panned out, they have a bunch of them now. They aren't too popular as most people just want / need the standard Glock rail. I would be very surprised to see it on other Glock models. |
the original 21SF was released w/ the full pic rail and ambi mag release; since then, mostly i think due to consumer requests, other variations of the SF came out, including non-ambi mag releases and old school, single pic rail mount |
Some accessories are only designed to mount on a MIL-STD-1913 rail. As such if you want to cross use any accessories with those already mounted on your long-gun, you might desire a 1913 rail. Sigarms did the same thing with the P226 X-Five Tactical
