Blemishes are cosmetic flaws with the laser engraving. Extensions are 100% functional.
The Mountain Tactical Glock Plus 5/6 Magazine Extension is a design collaboration between military and law enforcement professionals as well as elite D.O.S. firearms trainer, Ryan Allen of Green Branch.
Our goal was to create a low-profile magazine extension that would work with many of the magazine wells on the market, keep a low profile on the pistol, and not add the bulk and weight of the numerous magazine extensions available today.
Additionally, we sought to eliminate the problem of the magazine extension coming loose from the magazine as the empty magazine impacts the ground during run and gun magazine changes. Mountain Tactical has developed a proprietary retention system thoroughly vetted by top SWAT and SRT members.
They could not get the magazine extension to come loose by beating it against the ground!
Simply put, this is the finest magazine extension you can buy!
