Start packing the pistol you have wherever you can for a few days, even if it is only at your own house and yard, it may help you decide.
You might find that you prefer a tiny, light weight pistol because carrying is a hassle and annoying, or perhaps not.
Good advice. Where do you anticipate carrying it? What is your body shape? What kind of clothes will you be wearing?
I’m fairly slim and to carry an actually concealed large caliber in the summer is tough. Front waistband crotch carry pointing south is about the only way to do it.
Pocket guns, different deal.
