This is a good piece of gear. Very flexible. You can carry it on the left or right side and go with or without the flap. I have mine set up as a shoulder holster. This requires the accessory kit. Total cost was about $80 for everything including the kit. Exact same as I wore in the service when they switched over to the Beretta M9 9mm. You don't need a cartridge belt to wear it as it will accept a trouser belt up to 1 1/2" wide. The M12 holster has the added advantage of being a perfect fit for the 1911. This holster does a great job of protecting the firearm when the flap is installed. New here and I don't know if we are allowed to promote where it was purchased. If you want to know, just e-mail me.
