I posted about how I am planning on shooting one gun for a while and how I was going back to 9mm from 40. I had planned on getting a G34 to do this with but now I am thinking the G17 or even the G17C with an extra (non-ported) barrel might be a better choice. Any opinions? Is there really any big advantage to shooting the 34 versus the 17? What about the "C" model, does the ported barrel and lightened slide offer any real advantage over the plain G17? I know the sight radius is longer on the 34 and I know the advantages that Glock says there is for each pistol but I want to hear opinions from experienced shooters, people that have actually fired these guns. My thinking and what I have been told by alot of GSSF shooters is that the G17 (C model or not) would be a better choice for GSSF due to the fact that I can use it in every division besides Heavy Metal and SubCompact. It seems to make sense to me but the G34 idea comes from the fact I want to use the gun in alot of other disciplines. Will the 17 serve me just as well in USPSA, Steel Challenge, and IDPA?
