Designed for the B&T® APC45, this factory-built magazine holds up to 17-rounds of .45 ACP ammunition. Constructed from durable polymer, this magazine is built with the same level of Swiss craftsmanship you’d expect from their firearms. B&T is known for manufacturing some of the most advanced weapons in the world for elite military and law enforcement units. This 17-round magazine is perfect for situations where the typical 25-round magazine is too long, such as inside your daily carry bag or case.
