ETS Magazine for the SIG P320 - 21 Round

21-Round P320 Magazine

This ETS magazine gives a SIG Sauer P320 in 9mm a 21-round load. Its clear body shows how many rounds you have left without stripping the magazine or counting witness holes. It suits shooters who want more rounds between reloads at the range, in practice drills or in a spare-magazine pouch.

Features

• 21-Round Capacity — Holds 21 rounds of 9mm (9x19mm) in a double-stack layout, with the cartridges sitting in two staggered rows.
• Clear Polymer Body — The translucent body lets you check your round count and the condition of the spring at a glance.
• Fits SIG P320 And P250 — Built for the SIG Sauer P320 in 9mm and also compatible with the 9mm SIG P250.
• Anti-Tilt Follower — The black polymer follower is the platform the spring pushes up under the rounds, and it is shaped to stay level so cartridges feed straight instead of binding.
• Stainless Steel Spring — A stainless steel spring drives the follower and resists rust.
• Interchangeable Base Plate — The black polymer floor plate swaps with base plates from other ETS 9mm double-stack magazines.
• Marked For Identification — "Fits SIG 320 9mm", "Made in USA" and "21 Round" are marked on the lower body, so you can pick it out of a mixed pile of magazines.
• Made In USA — Manufactured in the United States by Elite Tactical Systems Group.

Fit And Construction

ETS molds the body from clear polymer and pairs it with a black polymer follower and floor plate and a stainless steel spring. The magazine is made for 9mm P320 pistols and also runs in the 9mm P250. If you already use other ETS 9mm double-stack magazines, their base plates are interchangeable with this one.
