For leather and short turn-around I recommend Desantis. My OWB for my Glock 30 is a Mini Slide: http://www.desantisholster.com/store/SE ... Mini-Slide
There is also a a Mini Scabbard that fits a Glock 19: http://www.desantisholster.com/store/SE ... i-Scabbard
Fairly short turn around times if they don't have it in stock. Follow the instructions on breaking it in. It fits/draws best after being worn for a day or two.
Just my $0.02
