If you’ve read any gun blogs or forums for more than a day you’ve likely come across a post or thread urging you to use a fucking holster. There’s a reason for that. Not using a holster can lead to a personal injury (or worse) that makes you look like a fool:
A Connecticut man, who accidentally shot himself while riding a bicycle, was arrested this week after lying to police and saying that a “gang” of men wearing black hoodies had attacked him.

But Docteur finally admitted that the gun in his waistband had gone off and he had shot himself after he was not able to explain why there was only a hole where the bullet exited from his pants. He was also not able to tell police what happened to his handgun after the incident.
I’ve mentioned the fact that I bike armed. When I ride my bike I lock my Glock 30SF into a Safariland ALS holster. My ALS serves two purposes: it prevents me from looking like a jackass like Mr. Docteur mentioned above and it prevents my firearm from coming out of the holster (it’s a potential problem when I’m mountain biking).
If you’re going to carry a gun buy a holster. Even a cheap, flimsy nylon holster made by Uncle Mike’s is better than nothing. An it’s far cheaper than the medical bills that you be accrue from sliding an unholstered gun down your waistband.
