Hi all, my dad has a Glock 21 he is not much a gun enthusiast, hunted in his teens, and pretty much stopped since he started his family. His Glock is fairly new and he needs a holster! I was thinking something, simple and cheap because you know how some dads are 'hard headed' you buy things for him and he won't use it! For this reason, i was thinking a kydex belt holster, some $20, but i know, i know he likes the $100 leather basket weave holsters like he has for his old S&W model 59. But, what do you all think, holster will be used just on range trips. So for you 50+year olds, what would you want, i think i may go with a kydex for my dad since the G21 sits in the safe most of the time. Blackhawk serpa? pretty secure stuff? Retention?
