This is the Mec-Gar 8 round .45 ACP for the Colt 1911 in a blued finish.
It features a carbon steel tube, self lubricating follower and linked internal parts to avoid losing components during strip downs. The spring is high tensile steel with a phospate coating for improved corrosion resistance.
The durable glass reinforced polymer baseplate is tapered to fit funneled mag wells where fitted.
