I am thinking of starting into competitive shooting in the Tampa Bay area. I currently have a 3906 and an SD9, each with two magazines, so with the intention of using the 3906 for matches, is that a good option?
For IDPA, need 3 magazines for either gun, holster that covers the trigger guard, holder for 2 mags and go shoot.
For USPSA, you will need 5 magazines.
Either can also be used for steel challenge.
Neither is red hot for bullseye.
Don't know what competition you have in mind, so can't comment further.
Make up your mind about which gun to use after you shoot some matches.
