Shooter’s Connection has the STI GP6-C in stock for $745. Having never shot one of these personally I can’t honestly say how good or bad it is as a gun, but I’m a sucker for Bo-Mar style sights and fiber optic front sights. The one thing I can tell you is that no Top-10 Production shooter in USPSA or Stock Service Pistol in IDPA uses one.
But they’re still cool, and for $750 for a competition ready gun that’s a hard deal to beat. Plus, STI is pretty well regarded in the competition community. The biggest disadvantage to this gun is that you have to manually lower the hammer before each string of fire to get that first double action shot. If you’re doing that in a match, it would behoove you to inform the safety officer of your plans before you stick your finger in the trigger guard.
