In the past few years, Galco has quietly added a locking holster to its thermoplastic Matrix series: the “auto locking” M4X and M6X design. Its simple and ergonomically advanced operation makes it one of the best ideas out there. The wearer’s thumb falls directly onto a rocking release lever on the inboard side of the holster—its movement matching that of the thumb as the shooting grip is acquired. Therefore, the user either rests his thumb on it or rotates it to the rear as his grip is finalized and the upward drawstroke is begun. It’s about as “natural” as you can get. Galco offers two separate models (the M4X is a paddle and the M6X uses a belt loop) to best meet its customers’ needs.
I use one of these holsters in my Methods of Concealed Carry lectures at the Annual Meetings of the NRA and people are always amazed at its simplicity and ease of operation; especially when they see how solidly its patented design holds onto the gun.
