The Mec-Gar Glock 17 Extended Magazine bumps standard G17 capacity from 17 to 20 rounds using a drop-in 18+2 round extension that requires no replacement of the mag catch. The heat-treated carbon steel body provides superior rigidity and long-term durability over polymer alternatives, while the high-tensile music wire spring ensures consistent feeding through thousands of round cycles. Mec-Gar's anti-friction coating reduces wear on the follower and internal surfaces for smoother, more reliable feeding. This is an OEM-quality upgrade that Glock shooters trust for competition and everyday carry use.
