I would only let a child of mine sit near him so that they can see what a SERPA holster is, and to make sure that they understood that if I ever caught them with a such a piece of garbage in their possession, I would beat them like a rented mule.
The Blackhawk Serpa is hardly a "piece of garbage", and is certainly better than some of those toy Kydex holsters in rainbow colors that some people are making in their backyard tool shed and selling to suckers over the Internet or in the booths next to the beef jerky at gun "shows".
I carry a Glock 30S in one daily, and have done so since around October or November of last year. It holds the pistol
securely, but as the pistol is drawn, the trigger finger naturally slides across the release tab, allowing the pistol to come smoothly out of the holster. The holster's adjustable for cant and ride height, and has slide loops that are adjustable for belt width. It also comes with a paddle if you like paddle holsters (I don't). It also has the ubiquitous tension screw. When you reholster, it makes a solid "click" to let you know the pistol's fully secured. Blackhawk seems to make a Serpa holster for every revolver and pistol in the known universe, and they sell tons of the things. They're popular with law enforcement for the simple reason that they do hold the pistol securely.
And if you somehow did manage to break the holster, you wouldn't have to wait weeks or months for a replacement. Just go down to the LGS and buy another just like it.
It's a composite holster for a composite pistol, simple as that. Both are utilitarian and both work really well together, and I don't worry about scratching or dinging either one. If I want pretty, I have a fancy floral EPS high ride holster and belt for the Glock, and a fancy floral 2-mag carrier to match. But I don't go to too many barbeques, and if I did, I wouldn't carry the Glock.
Luddite that I am, I used to swear I'd never have a "plastic pistol". Then I swore I'd never have a "plastic holster". Uh-oh. Wrong again.
You're entitled to your opinion, of course, but don't knock it if you haven't tried it would be my advice.
And
why would you beat a mule, anyway?
