A very worn in leather holster can fold in to the trigger guard when holstering/reholstering if you’re not careful. Even with kydex, you still have to worry about T-shirt’s or other clothing getting caught but it’s one less thing to worry about.How is that?
Kydex makes reholstering much easier and safe for that reason. Kydex is generally going to give you better or equal results with a slimmer profile.
Another benefit is kydex doesn’t retain moisture like a leather holster. I can leave my carry gun in the holster 24/7 without worrying about rust if I’d like to.
I miss the excitement of breaking in a new handmade fancy leather Rosen holster or similar but kydex is just much more convenient and safe in my experience.
Pictures aren’t mine but an example of what can happen.
