Look at the 7 Series Safariland then, if it's the looks you're worried about. As far as actual size, a Safariland ain't that much bulkier than a G-Code where it matters, and once you have the holster, there's a myriad of mounting options for it, from paddle close to the body to full-on GWOT looking thigh rig setups, and everything in between.
If it's a range toy or for gun games, that's one thing. Bodkin your ass off, enjoy your Quick-Draw McGraw rig.
But, if it's meant to possibly be with you in harm's way, I'd want L2 retention at the very least, and a holster that seriously protects the weapon that's supposed to protect you and yours...If you're strapping on a battle belt, things are already overt...if you're not jocked up, that's what a CCW setup is for. Don't cross the streams, suit gear to task.
Just sayin'.
