I may make adjustments for season or clothing. My EDC may be either a Glock 27 or Shield 40, including on gym days, but if I will be wearing a heavy sweater or sport jacket that affords greater concealment I may step it up in size to a Glock 23. My PM9 hasn't come out of the safe in a long time.
I may, "rotate" ammo for better performance through heavy clothing in winter. I like the all copper hollowpoints such as CorBon DPX in winter.
