I'm looking a holster for an HK45 and need some suggestions.

this will not be used for concealed carry, mainly for range work and when out plinking at the deer camp and stuff.

I'd like it to be an on the waist holster, maybe a drop leg.
and for it to be able to accommodate the HK45 with a light on it (either a streamlight TLR-1 or TLR-2 not sure which one I'm gonna get yet).
don't really care what material it is made of
and not looking to break the bank, so under $50 if possible.

You would be better off asking your questions in here:

G-Code, Comp-Tac, NTAC, Kaulban Cloak, Bladetech, Safariland, and many others.

This is a great holster system. It also comes with the belt loop attachment.
