Well, I guess it comes down to use and value - cost/benefit. If you shoot matches and rarely carry, yeah, it makes little sense.
Now . . . if you take a 2 or 3 day class, you'll appreciate a stable holster, one that will reholster one handed. But, not many people do that - take formal instruction.
Look, I've always viewed the purchase of leather gear not from the shooting aspect. My gear has to keep my handgun, mag, and light stable, do it comfortably, and keep it in place and hidden. I carry from when I put pants on in the morning until I take them off at night. I don't want my coworkers knowing, and I want to be comfortable. Its an investment for me. Its not about being able to quick draw or anything else other than having my stuff stay put, tight, and be comfortable as I move about my daily business. A $50 might do it, and a $100 might. I don't care about the cost, the benefit is what I need. I won't wear and IWB holster for that long; its uncomfortable. I use OWB rigs. I know Milt Sparks and Rusty Sherrick's gear will do it. So, that's what I buy.
I have often wondered why some find miserliness in this area admirable. I mean, some guys really flaunt the fact that they didn't spend more than $20 on something to carry a loaded weapon around. Hey, I have cheap nylon for a pocket gun, too. But . . . well. I guess I have my own opinions on these things.
In reality, I find most who have this attitude don't carry a gun around nearly as often, so I guess I can accept it. But, I can't accept it when someone asks for help finding something to perform to those standards, and guys say you need to ditch the Uncle Mike's mentality and get better gear. Then I see these folks step up and counter it, praising insufficient products because they're cheap. Until you carry something that's not a subcompact past 12 hours a day, every day, discretely, you aren't in a position to challenge the advice to make an investment in your gear.
