This club is to recognize those who have gotten at least ONE kill with the highly elusive M1911 S-TAC sidearm, a DICE developer-only weapon.

The M1911 is wonderful! Why put only ONE attachment on it at a time?? It's like a little flashbang gun...they can't see you, or hear you!

If you got an S-TAC kill, you MAY be eligible for another group if you've managed to get one kill with EVERYTHING: http://battlelog.battlefield.com/bf3/platoon/2832655241323061505/
