The 5.11 tactical vest is known by many names: concealment vest, handgun concealment vests and undercover vest. So no matter what you call the 5.11 Tactical vest it will fit the bill for your gear and handgun concealment needs.  5.11 Tactical was developed in 1968 built on a foundation of durability, functionality and quality. 5.11 is a difficulty level in the Yosemite Decimal rating scale for rock climbing. You do not have to be a rock climber, Law Enforcement or emergency personnel to appreciate the high quality and comfort of the 5.11 Tactical vests. Need personal testimony?  Then speak with our staff, we wear 5.11 clothes everyday for work, casual wear and on duty. The handgun concealment vest will fit most handguns, just don't try to conceal a 44mag Desert Eagle in you undercover vest. It just ain't gonna work. Now I've carried on duty a Glock 22, four extra magazines, two sets of handcuffs, keys,  radio, Quaker Oats bar (peanut butter), note pad, pen and documents in my handgun concealment vest.
