32 Law Enforcement Technology January 2016 FIREARMS TACTICS U.S. using U.S. parts and labor. Look for consistent weld beads on magazines that aren't spot welded. One of my favorite .45 magazine manufacturers is Metalform. I have some Elite magazines with Wolff Springs and round followers. They are the standard on the range. W hen I'm on the range testing new ammo I use them because of their consistent performance. If you have not heard of Metalform, it's ok. If you are carrying a name brand gun that uses metal magazines for duty, Metalform likely made your magazines. Consider your magazines expendable If the magazines fail this or any subsequent inspection, don't toss them…mark them. In fact, save all of your questionable magazines. They are the best range training tools ever. Firearms trainers spend a lot of time trying to induce failure when training. I use my worst magazines in order to experience an unex- pected failure. Rather than tossing magazines I sort them. I use stock magazine bodies, but all of my maga- zines have Vickers Tactical Magazine Floor Plates from TangoDown. Not only do they have a wider profile, they have aggressive grip surfaces for positive extraction, even in really, really bad territory. The Vickers Plates come in colors and they have eight dots on the bottom. For me, the black and Glock tan ones are for duty, blue are for training. The orange plates are for specific types of training. The dots on the bottom allow officers to number them, the best method to rotate rounds and record maintenance. The second part of the inspection is to look at the feed lips. They should also be devoid of chips or cracks, but you are looking for a consistent curve around the cartridge. All feed lips should have the same curve. When empty, the follower should push all the way up to the lips. Next, if the follower doesn't go all the way up, or if it rattles when shaken, begin by replac- ing the magazine spring. Use Wolff replacement springs or OEM. If your gun is a Glock, use only Glock springs. Bear in mind that not all magazines have interchangeable parts, even ones supplied with a purchased gun. Disassemble magazines separately. Look to see if the magazine holds cartridges correctly. This inspection includes eyeballing, but the important test is to bang them. Fill the magazine to half its capacity and bang the base on a table. The force should be sufficient enough to cause the cartridges to move down slightly. An alternate version of this test is to drop them on the ground (the ground, not concrete) from waist level. If cartridges fly from the magazine, it failed the feed Many magazines have a hole in the bottom for disassembly. Stick a punch into the hole, then slide the nose of the floorplate toward the nose of the magazine. The baseplate will have an insert underneath. The spring and the follower should come out the bottom. After disassembly, it's time to inspect the follower and the inside of the magazine body. D&H magazines for the 7.6 2 x 39 cartridge have a very pronounced curve in the center. Coupled with the green follower, they are extremely reliable. This follower doesn't get hung up in the curve like similar magazines. The feed lips really make a difference when a 30-round magazine is full. Circle 42 on Reader Service Card
