No problem. Most gun nuts are just in it for the fashion statement.
That shows how little you know about firearms or those who carry them on a daily basis. A holster isn't a "fashion statement", it's the most important accessory you need to safely carry. Only an idiot, a Chicago street thug, or a Mexican would simply stick a pistol in their pocket or tuck it in the belt, sans holster.
The purpose of a holster is not only to protect your weapon against dirt, dust, sweat, and rust, but to protect yourself and everyone around you from accidentally being shot. I went through ten different holsters before I decided on the one I'm using: It's very concealable, even in the Summer with a light shirt. It has plenty of retention, so the pistol can't accidentally fall out or be grabbed from behind.
It also keeps the muzzle pointed in a safe direction, at about 10 degrees toward the ground behind me, away from the leg and the femoral artery. The worst thing you can do is tuck a pistol in your belt or use any holster that points the muzzle at the inside of the leg. Shoot yourself in the femoral artery, and you're basically fucked. Without a tourniquet, you'll bleed out and die withing minutes.
