40mm Belt Holsters & Tactical Gear

40mm belt holsters and magazine pouches represent the standard width for most duty and tactical belt systems across Europe. This measurement refers to the belt loop or attachment width, ensuring compatibility with professional-grade 1.5-inch belts commonly used by military, law enforcement, and competitive shooters. At No Boring Guns, our 40mm-compatible gear includes both inside and outside waistband holsters from RH Holsters, featuring their proven retention systems and durable Kydex construction.

The 40mm standard provides optimal weight distribution for carrying full-size firearms and multiple magazine pouches without belt sag. This width accommodates most paddle attachments, belt clips, and MOLLE-compatible mounting systems. Whether you’re selecting a Classic IWB holster for concealed carry or an OWB setup for range use, verifying 40mm belt compatibility ensures secure retention and prevents holster movement during draw. Most European tactical equipment manufacturers design their professional holsters around this specification, making 40mm the most versatile choice for building a complete carry system.
