Pros: A good reliable mag.
Cons: The parkerized finish needs to be oiled to prevent rust.
The Browning High Power pistol is the brainchild of legendary firearms designer John Browning and Fabrique Nationale engineer Dieudonne Saive.
Originally designed to meet a pre-WWII request from the French military the pistol has remained in continous production since 1935. It has proven be a popular sidearm in both military service and in civilian hands.
Among the pistol's innovations is it's magazine: The High Power was the first to use a "double stack" magazine where the cartridges do not line up exactly on top of each other. Instead they are staggered in two columns in the relatively wide body of the magazine. The magazine body itself tapers towards the top, which forces the last few rounds to line up directly on top of each other so that they can more easily fed into the pistol's chamber.
While common now, at the time this double-stack, high capacity design was revolutionary. The original magazine held 13 rounds of 9mm ammunition. Modern versions of the High Power magazine hold anywhere from 10 rounds up to 17 rounds.
This review is of the 13 round Browning High Power magazine manufactured by Mec Gar for Pachmyr. Mec Gar manufactures most of the magazines used by gun manufacturers as "Original Equipment Manufacturer" magazines and also makes magazines for other vendors and under their own name. Mec Gar magazines, whatever the name on the package, have an excellent reputation for worksmanship, materials, durability and reliability.
The magazine is made up of the mag body, floorplate, spring, follower, and integral feed lips.
The mag body is standard thin sheet steel. The Pachmyr marked High Power mags I own have a Parkerized finsih for corrosion resistence. This is the old standard military finish and works best if oiled regularly. I believe blued steel Pachmyr marked mags are also available, but I have not seen them myself.
The floorplate on my examples is plastic with the Pachmyr logo. The floorplates have resisted breakage or damage in normal use being dropped during range drills and competition. The floorplate can be easily removed for replacement if it does get damaged.
The springs are standard music wire springs typical of those used in the industry.
The follower is of the standard design for the Browning High Power. I have not had any problems with the followers tilting or "nose diving" with these mags.
As with any double-stack magazine, getting the magazine loaded to full capacity can be difficult, especially when new. The trick is to load as many rounds into the magazine as you can and then let the magazine sit for a day or two. After that time the mag springs will take a small set and you should be able to insert the remaining rounds. The springs will not take any extra set from normal use after they are first broken in.
The Browning High Power is an excellent design and these Pachmyr marked mags are an excellent choice for this pistol.
