The ALG Supersonic Gen 4 Magwell are precision machined from billet 6061-T6 aluminum and is designed to seamlessly fit Gen 4 Glock 17, 22, 24, 31, 34, and 35 without modification to the Magwell or the Glock pistol frame itself. The AFM is finished using a type 3 hardcoat anodize process which allows the it to be long lasting and durable.
The ALG Defense Flared Magwell (AFM) is required to make speed-reloading faster by decreasing the precision needed to insert a magazine into the pistol. Additionally, the flare of the AFM acts as a ledge to spread the recoil impulse into the bottom of the gripping hand. The ALG Flared Magwell is designed to fit Gen 3 Glock 17 and 22 pistols. It will not fit Gen 4 pistols and its compatibility with other Gen 3 Glock pistols is unknown.
