It wasnt a Glock 34 thats for sure. Although USPSA legal, a 34 isnt ISPC production legal. Its too long and the trigger pull is under the 5 # limit. He most likely used a G17.
Other than that I know
Leatham used an SA hi cap .40
Jarret uses a Para .38 super
Max Michel and Mike Voight shoot STI Guns.
Frank Garcia shoots an Infinity.
