Great post. I was one that fell into the category of "always searching" for a long time. I have now pretty much settled in with regard to holster styles and stick with only the GLOCK platform for carry guns. I still have other firearms but the bulk of my practice and all of my training, matches, and carry is done with a GLOCK.
I have my GLOCK all set up pretty much the say way with respect to controls, sights, connectors, spring, etc. Yes, the grips are somewhat different between models/mods and the triggers do have slightly different feels based on the amount of use. However, I feel I'm pretty consistent with a G26/G19/G17/G34.
Am I fooling myself? What say the SMEs?
