I shoot carry guns (slowly, compared to regular competetors). Usually 1911's or Smith Wesson Revolvers.
I have hesitated shooting IDPA or USPSA "sanctioned matches"... at this age "joining" just doesnt have the appeal it did in the past.
While it may be true that the $40 you spend to join USPSA supports the shooting sports, you DO NOT have to join USPSA to shoot at the matches. I am not a member of either NRA or USPSA right now even though GC is.
Please don't let these guys dissuade you from coming out. Their just afraid you're gonna skin them! It is a lot of fun ... I still show up and I can't even shoot right now.
Bring your 1911 and shoot single stack or your revolver and shoot revelover (duh! lol). While it is not formal training by any stretch of the imagination you will become a better gun handler just by virtue of the little timer going "BEEP" LOL You won't be sorry.
(I'll bring cookies and pecan brittle just for you ... Just PM me ... )
