Police responded to the scene and determined that a person who had a valid concealed firearms carry permit was seated in the theater and had accidentally dropped his firearm to the floor and retrieved and re-holstered it.
I have no idea what kind of holster this man had. What is clear is that the holster didn’t perform a primary function, to wit: keeping the gun in place. Who knows, it might even have been the crappy holster that inspired my Scam artists in the firearms community post.
Keep in mind that when carrying a gun in public, eventually you will probably sit down. Make sure your holster doesn’t rely solely on gravity to retain the gun. When you sit or slouch, that’s going to stop working. Either a retention system or being fitted to the specific handgun is important.
When carrying a pistol, the gun and holster form a system. That system has to work in a lot of conditions other than what you will encounter at a gun shop or shooting facility. Have that fundamental reality as part of your purchase decision.
Safariland, Galco, and even Blackhawk make decent holsters. Well, some Blackhawks, anyway; my distaste for the Slurpa is well known. But I’ve never heard of a Slurpa letting the gun fall on the ground in a movie theater, so there’s that. There are numerous smaller manufacturers who make high quality gear, as well. One clue is that if it’s made from nylon fabric, you should probably choose something else.
Having to interact with Law Enforcement because your gun fell on the ground is a Serious Mistake. Don’t scrimp for a few dollars and put yourself in that position.
