When choosing beltman belt size, can I use the measurement of the belt on with a leather holster if I'm going to use a kydex holster also?

I've decided on a beltman horse hide belt with internal stiffener.According to their sizing guide, I put on an existing belt with the Bianchi #100 holster I have. I'm a 34 waist, and with the leather holster it's snug at 38.Current holster in question.I'm getting a Vedder Lighttuck in the mail in like a week, but I'm a bit impatient and want the holster made ASAP. via /r/CCW http://ift.tt/2DN67Ur
