I'll start off
Springfield Armory XDM 40S&W 3.8 inch barrel service pistol - home defense and on heavy coat days only. It holds 16+1 for 40 cal power so whenever I can carry it I do. But it's hard to conceal.
Springfield Armory XD9 sub compact - my current EDC. It's a small fairly concealable double stack with 13+1 and 16 in the backup mag. Enough to get me through most disasters. Only fits under sweatshirts, sweaters and really baggy t shirts.
Springfield Armory XD 45ACP sub compact. A higher power alternative to my XD9sc. 10+1 and 13 on backup of a powerful man stopper round makes this a dead heat for EDC. The barrel is 1 inch longer and it busts my concealment sometimes so I only carry it on heavy days.
Ruger LCP. Nuff said. Deep concealment. I will always have at least this with me. .380 ACP is meh but it will do the job.
Ruger KLCR for grab and go simplicity and reliability. It's really the red headed stepchild of my rotation but it has its place. When everything else fails I grab this 5 round wheel gun. Conceals really really well. Second only to the LCP. So it's going to be a summer favorite.
My newest golden child: the S&W M&P Shield 9mm!! I haven't shot it yet but I'm sure I'll love it. Summer gun all the way and will always be with me in t-shirt weather unless I put on the speedos then it's the LCP. When the weather gets colder and clothes get thicker, the XD9 goes back into service but I think this one will be my EDC when the sun is baking.
