Actually I took a Remora, and cut the stitching that outlines the Muzzle, cut it with my EDC knife. It then did take my Glock 26 with a Viridian Tac light, also if you buy a "Holster Clip" on Amazon or EBay, you can glue it permanently to a Remora with Loctite blue, or probably "crazy glue also", giving you the option to use it IWB, with the light or not.
I personally never felt they were secure enough with nothing but the body against the holster alone, and found them capable of sliding around without the clip on them. Plus they still work in the pocket. The clip is on there 2 years, it would have to rip to get it off.
They did put a clip on them this past year, with a snap or rivet. I had sent them a photo of mine a couple years ago, but never heard anything. I am sure I am not the only one who did this.
But it ended up that I took the light off of the gun, only because it made the package too bulky. That new clip I got is the one that snaps on like a vise, I plan to use that in a holster that I have in the planning stages, as I don't wear a belt most of the time.
I Have had disk surgery and spinal problems for most of my adult life. I have a problem with belts cutting into my spine. I am always looking for something that will support a pistol without a belt, "hard to do with anything over 20 ozs".
But I ordered that new "Cherries" holster 3 months ago, they are really backed up, because of the John Wick movie. I am looking forward to getting it as it is supposed to work without a belt, or with. It sits below the belt line, and if you don't mind your gun laying on the jewels, it is supposed to be the best in deep cover for Glock 26-19 sized weapons, and it has a side holster for a small blade, it's designed after the Teddy Medina, famous hit man from the Philippines, by Aron Cohen, the Israeli security expert who trained Reeves for the flick.
here is a link for thr holster,
