These days I carry a CZ75 compact. Great little gun, but thick compared to a single stack... Anyways, I've been pondering about weight lately, and comparisons from a gun to another: I'm lusting for some aluminum-framed 1911, and been dissecting differences from one to another (barrel length, caliber, weight, and all the life-changing details involved in a potential new gun ). Thought to myself, several times "2-3 or even 4 ounces one way or the other... Won't make much difference... Or would it?". I realized that the 75, full with my carry ammo, is 2oz above the minimum weight I can get in a DW ECO, with light-for-caliber ammo. So I removed 5 rounds from the mag, which gets the 2oz off, and carried it like this for a few days. Still carrying it this way, actually. And, you know what? These little 2 ounces actually do make a difference... I was not expecting that, but I definitely feel a difference at the end of the day. What is your experience?
