I second the Safariland 6280. It can be had in "nylon look" or another finish called "fine-tac," which I prefer. Check out the Safariland website for further details. I've tried a few different duty holsters, but always come back to the 6280.
SUPRISE, SUPRISE!!! I got an e-mail today from safariland... I won their drawing for the October free holster! I looked at the one you guys recommended and I like it. I asked for it in my responding e-mail, but the fine print says it needs to be from their civilian line. I'll wait and see what happens.
