I have multiple holsters for SIG, Glock, and Smith & Wesson pistols from Tier 1. I could write a whole lot on why these are great holsters. I tried tons of other holsters and wasted the money. Now if I get a new gun or set up I go strait to tier 1. Spend the money right the first time or buy twice.
What it comes down to is comfort and printing. And I can say from experience these holsters are comfy and low profile. Very functional to deploy the weapon, conceal it and retain it.
