Smaller in summer for sure -

How big of a guy are you Cleanisfast?

I'm 5'7" 190 athletic build and not zombiefied about occasional printing so in the summer I would be IWB under a T-shirt - Glock 26 Gen4 right now, but I also have a Taurus 605 2" barrel revolver if I wanted to carry a wheelgun (which I'll admit isn't too often, I reach for my Glocks) -

I may be adding a Glock 43 in a few months (I get a Blue Label discount from GSSF membership around end of May each year) as the single stack is just a bit easier in summer, not by much - In winter I'd have no problem with my Glock 19 Gen4, but I wouldn't go larger than that, personally -

Sig P320 is great choice, I assume you mean the 15+1 Compact? The Carry has a Full Size grip length and 17+1 capacity, and the P320 is just a hair larger than a Glock 19 in the Compact configuration if you put them side by side -

Great pistol though, I'd also look into the P320 Subcompact if you can find it in 9mm as its a bit bigger than a Glock 26 and is 12+1 very respectable capacity - small grip is very slim as well -

Now Sig keeping magazines, different size grip frames etc in stock is a whole other thread that belongs on SigTalk.....
