Brian has written a review STI’s GP6-C pistol. It is their offering for USPSA Production and IDPA Stock Service Pistol classes:
The GP6-C is race-ready out of the box. There’s no need to spend a lot of money on a heavily customized SIG, Glock or XD, nor go to the trouble of installing aftermarket parts. Even with hundreds of dollars in aftermarket triggers and components, you will only come close to the single-action trigger on the GP6-C, probably its most outstanding feature. It is a new gun, so accessories are scarce, but I’ve found three suitable holsters and magazine holders. I’m very impressed with the GP6-C, and you’ll see me shooting it in IDPA competitions in the coming months.
I shot it as well and liked it. Especially the SA trigger, with an extremely crisp 3lb trigger and next to no reset. I’ve got my G34 pretty well slicked up, at a cost of about $1100 dollars if I add it all up (and I DON’T usually!). Some of that isn’t in the gun still, you have to try stuff and see if you like it.
The GP6-C offers race ready, no-hassle performance, for $600-$700 bucks.
It is also light and a pretty decent home defense / carry gun.
But hey… read the review, he covers it in detail.
