What’s a solid pistol and PCC combo? Looking to save weight with a bug out bag.

Considered a PCC that takes Sig P320 M17 mags and going 9mm but don’t know if I’m sold on that handgun just yet. Also considered but haven’t looked as close for stuff that takes Glock 19 mags. Since those are more law enforcement or military relevant in case you needed spare parts etc.

I don’t really have a budget. I’m not going to the spend money for the bragging rights range but if $2500 gets me quality for the rifle (not counting the pistol) I’m okay with that.

Considering .45 ACP, 9mm, and less likely but not counted out .357 and 10mm.

I grew up with guns and practice semi-reg but I’m no know it all. I’d consider myself a competent novice who grew up around guns and hunting.

Thanks for your help and patience.
