The Hank Sloan-designed holster was created exclusively for the FBI's S&W Model 10 M&P . 38 revolver. The accompanying 2 + 2 + 2 a.m.mo drop pouch was used to quickly “top off” bullets in the cylinder of the revolver when reloading.

If all you have to do in order to remove the weapon from the holster is lift it at a certain angle, then it's classified as a Level 1. If you have to remove a hood or press a thumb break AND then lift the weapon, it's a Level 2 retention system.

It's important to buy a holster that's molded for your exact firearm to ensure proper retention. As silly as it sounds, you don't want your gun to fall out of your holster when you bend over because the holster is too loose or have trouble retrieving your gun from the holster because it's too tight.

Concealed carry holsters can have a positive impact on gun safety. By securely holding the firearm in place, these holsters prevent accidental discharges that can occur when a firearm is not properly stored or secured.
