I have been shooting a G34 the last couple of years, but I plan on shooting a G19 in CCP this year.  Don't know how many others will follow suit.  I typically carry a G19, but I caught the competitive spirit and wanted to win every chance I got.  Now I can still do that and compete with the gun I normally carry.

Will still use the G34 for 3-gun, Action Pistol, Steel Challenge, and USPSA.
