I typically carry a 19 or 26 in an Eidolon. For the 19 with a Streamlight TLR-1, I just bought a
Bravo DOS light-bearing holster and added a
Raven Claw so it works very similarly to the Eidolon.
I thought about a Sidecar, but was concerned about the placement of the spare mag. It seems to stick up and out farther than I'd like; but I don't have one to play with so that's just a guess based on photos. I just bolted a Glock brand mag case to the DOS (just like I did with the Eidolon) and it does just what I want.
For a belt, I have the 5.11 and it's decent. I've switched to a
Frank Proctor BELT. I find it more flexible and therefore more comfortable, but it's still reinforced in places. It's a little pricey, but I think it's worth it. Seemed flimsy when I first bought it, but I work in a pretty physical job (lots of bending and twisting) and I've noticed no wear after 6 months.
I'm still looking for a good solution for my Shield. Right now I have a heavily modified
Blackhawk ACR, but I haven't found a setup I like. I'll tag this thread for more ideas. Don't have a light for it yet, just want something tuckable and very concealable.
Hope this helps.
