SJ Hardware Glock 1oz. Metal Base Plates are 1 ounce or 28 gram Glock magazine base plates that replace factory magazine base plates. They will fit Glock 17/19/22/23/34/35 models.They are CNC machined from 6061 T6 Aluminum. 6061 T6 is known as a multipurpose heat treatable aluminum alloy that provides excellent corrosion resistance, strength, machinability and weldability. The Glock 1oz. Metal Base Plates are CNC machined to meet the exact dimensions of a factory magazine and maintain a high standard of quality control. The Glock 1oz. Metal Base Plates are Type III hard anodized which is the same specification required for most Milspec contracts. Type III aluminum anodizing increases the wear and corrosion resistance, enhances the surface hardness, and improves the thermal properties of treated aluminum objects.
The DotMatrix Labeling system is a series of machined divots on the bottom of the Glock 1oz. Metal Base Plates. Three rows of six divots which can be filled in with a paint pen or permanent marker to track your magazines by an alpha numeric system of your choice.
They do require some fitting though. First remove your factory base plate from your magazine. Along the sides of the base of a factory Glock magazine are two nubs, one on either side. These need to be removed to attached the SJ Hardware Glock 1oz. Metal Base Plates. I used a sharp box cutter. Please watch the video below on a detail explanation to fit these baseplates. I did it one afternoon as I detail cleaned my magazines and have been running them on my Glock ever since.
SJ Hardware states that their Glock 1oz. Metal Base Plates are compatible with most aftermarket magwells. I run a Lone Wolf magwell on my Glock 17. The Glock 1oz. Metal Base Plates has added just enough length to improve handling during induced remedial action drills, reactive reloads and proactive reloads.
My entire pool of magazines has been fitted with SJ Hardware Glock 1oz. Metal Base Plates. They have run flawlessly since installation. Occasionally, with factory bases, there were hangups when ejecting a magazine. Usually, when I brought the gun into my workspace too quickly before the lighter factory magazine cleared the magwell. With the heavier Glock 1oz. Metal Base Plates, magazine ejection and drop free reliability has been enhanced. This has slicked up my reloads which reduced my reload times noticeably.
For faster reloads, enhanced drop free reliability and improved handling, I recommend this product over the factory bases.
