Got a Theis OWB holster for my Glock 26 with Crimson Trace Laserguard recently. Price was reasonable, and the holster arrived fairly quickly. The quality seems very good, and I like that the top of the kydex is beveled so that holstering is easier - it helps guide the gun in. Little details like that are nice!
The holster does creak a bit, and the paperwork that came with it warns about this, along with some suggested remedies. I'm going to wear it a bit more to break it in before resorting to them.
There are not too many OWB choices out there for a Glock with the CT Laserguard attached - so if you are looking for one, give these folks a try. They are forum sponsors as well.
