Me, too --- I'm not big on that broad, flowing "reinforcement panel" on a holster. Basically just making it thicker, while trying to conceal it, which seems ... uhh. not the best idea.
In fact, often a holster doesn't require any "reinforcement" at all. But, I do 'have' them and have done them. As a rule, I mold it if it's solid color and/or plain, and I don't mold it if it's tooled. But, like I said, unless you're tooling it, I dont have much use for a full panel. Something more like this (which, by the way,is also about 1" wide)..
