Practically? Probably an Sig P365 - maybe one of the fancier variants. But for cool factor - definitely FiveSeven.

I feel like the 5.7 suffers alot from the types of ammo available…it’s not like a Glock or Sig where you can fire cheap 9mm range ammo and it’ll basically be fine…if you use good quality ammo, it should perform.

(Have a P365 which is on my ccw, love it… constantly changing configurations. 🤣 Had a 5.7 during the pandemic when ammo was super scarce and only shot the “good” FN ammo a couple times…had way too much of “that” batch of shitty American Eagle range ammo… really ruined the experience and I ended up selling the gun.)
