I've been looking for an OWB holster for my Glock 43X for quite awhile. I bought on Amazon an Orpaz C-Series G43X Level II OWB. (Around $37.) An absolutely fantastic holester! Holds the Glock perfectly secure and has the "level II" thumb release for greater security. (Which works perfectly.) I'm very pleased w/this purchase. Not sure how it may be for other Glock models but w/the 43X is a great match. Check it out....may be exactly what you're looking for as well.
