Uncle Mikes has a clearance sale on a holster that fits the .40 and .45 frames, after buying one to try I got a couple more for spares. It's #19, Askins style in the clearance section of their site
www.unclemikes.com. I wear it outside the WB, but it's ambidextrous, and could probably be worn inside, using the LH belt loops on the RH although it may be a bit tight for reholstering one-handed. I've been using it almost daily a couple of months or so w/ no problems, without the safety strap, which is rather chintzy. But then, what can one expect for $7.67.
If that's too cheap, just remove the POS roto part of the Fobus, Dremel out that which would interfere w/ a belt, heat it a bit so you can spread out the (new) belt slots and you have a snug fitting holster that doesnt' stick out two inches or so from your belt. At least it worked w/ my XD40.
Yeah. I'm cheap, and like to make things work; why else would I be messin' w/ Tanfoglios?
