I have never seen a pro shooter, shot sti guns, unless they were sponsored by them, and I happen to know that even those guns dont have all sti parts in them. simply put all the semi-pro and hobby shooters love sti for one reason, they are CHEAP.
The owner of sti, Cares about 1 thing, money.... SVI is the staple of 2011 guns, every race, limited or open gun I have built has been on SVI chassis with caspain frames. now for those here that think they have a pro style gun, and it's an sti in 40 cal, you are wrong. all the pros shot 9x23 or 9x25 and they are svi chassis's and highly modified and cost way more than 2200.00 bucks out the door.
You would be better off with a rock island than and sti single stack, reason, you save about 300.00 bucks for the same damn gun.
Thanks,
A
