The SIG P365 10-round extended magazine is perfect for shooters who want extra grip without extra bulk. Designed for the standard P365 9mm platform, this factory OEM magazine features an extended polymer baseplate that provides additional length for a fuller, more secure grip.
Built from durable black steel, this magazine includes a polymer follower and delivers smooth, reliable feeding with every round. Whether you’re carrying daily or training on the range, the improved control of this mag makes a noticeable difference—especially for shooters with larger hands.
It maintains a 10-round capacity, making it compliant in restricted states while improving ergonomics over the standard flush-fit version.
