I am thinking about trying IDPA and I am looking for opinions on which Glock to use, I am leaning toward a nine but can't decide between the G17, G19 or the G34. I have a Kimber Pro Raptor II .45 for my carry weopen but it may be too heavy for the Florida summers. I have a Glock 26 but my wife took it for carry gun. We also have a couple of snubnose .38s from S & W and Taurus. I was also wondering if most IDPA shooters are taking aim with the sights or point shooting, I don't think I could get on target with the sights as fast as I have seen. Only 45 not blind, we both get in about 100-150 shots per week at the range we belong to, and the nine would surely cut the cost of shooting the .45 so much. I do love both the Glocks and the Kimbers. My 4" Kimber is a hell of a tack driver but 200 shots in an afternoon and 230 grain FMJ will beat you up. Any other information is appreciated.
