There always seems to be talk about the weight of the firearm.
I don't get it, maybe because I'm 6' and 200 lbs.
With the proper holster with proper belt or harness
there isn't anything I own that I can't carry
all day in comfort.
IMHO size, weight and bulk vastly contribute to how a firearm can & can't be comfortably carried, depending on dress, climate conditions and carry methods.
These days we live in a warm climate and my daily dress is usually a T shirt and Cargo Shorts so pocket carry became my best option. A large, heavy and bulky pistol just won't "cut it"! I EDC a Sig P365 which puts a lot of meaningful firepower in a very small and light package and is able to comfortably and conveniently be carried in the pocket of my Cargo Shorts. I carry for many hours at a time and do not care to wear excessive clothing to hide a large hand gun.
I guess if you routinely carry a gun, live in a cooler climate and usually wear a suite, sports coat, sweater or jacket, then options become greater. I like to fit in dress-wise and don't want to have to wear ridiculous clothing to dress around a gun. I LMAO when I see someone who is wearing a photographer's vest with shorts in 90º plus temperatures - and has no camera equipment.
While some can learn and train themselves to carry any size hand gun, I truly can't understand
why if there are better options readily available. I know some here carry a 4" - 5" M681 (or similar) 357 Magnum on a daily basis, but that gun shoots the same cartridge as a 2.5" M66 and even some smaller J Frames. While the larger frame gun will admittedly be easier to shoot fast and control with less practice, there is much to be said for practicing with a smaller SD weapon to learn how to do that as well.
The very reason I retired my M60-7, 5 shot .38 Spl. and now carry a Sig P365 is that the Sig weighs in at 5 ounces less, is smaller, less bulky, shoots better and is more accurate than the J frame. Add the fact that I went from 5 rounds to 11 rounds on board and easier and faster reloading, it's a no brainer to me. The stopping power of the ammo I carry in the Sig is more powerful than what I carried in the J Frame and so that decision was easy to reach.
I always say, "to each his own" and everyone needs to do what they have to do. To me, a lighter and smaller package that shoots the same or equivalent cartridge is just something that I can't over-look. YMMV
