I was very consistent with my EDC before the double-stack micro-9's hit the market over the past few years. I carried a 9mm Beretta PX4 Storm Compact when my kids were young because I wanted a weapon with an external safety. When my kids got old enough to learn to shoot, I switched between the Glock 26 and Glock 19 (based on wardrobe) for years.
Since the micro-9s hit the market, I have carried a Sig P365, a Glock 43, a Glock 48, and a Shield Plus. I've settled on Shield Plus (for now) because the wide, flat grip gives me the best purchase on the handgun and is easiest for me to conceal with my body type. The only thing that could get me to change now is if Springfield designs a stack-and-a-half XDS.
