Sig P320 21-Round Coyote Magazine

Features

1. 21-Round 9mm Capacity — Factory extended magazine holds 21 rounds of 9x19mm for fewer reloads at the range or in duty configuration.
2. OEM Sig Sauer Build — Same magazine that ships with the U.S. Army-issued M17, built to factory spec for guaranteed fit and function.
3. P320 / M17 / M18 / P250 Compatible — Drops into full-size P320 frames and is cross-compatible with the M17, M18, and 9mm P250 platforms.
4. Coyote Brown Polymer Baseplate — Coyote-finished baseplate matches M17-pattern pistols and other coyote-themed loadouts.
5. Steel Magazine Body — Heat-treated steel tube delivers durability and consistent feed-lip geometry over thousands of cycles.
6. High-Visibility Orange Follower — Bright polymer follower aids in identifying an empty magazine and promotes reliable feeding.
7. Witness Holes — Numbered round-count witness holes on the side of the body let you verify capacity at a glance.
8. Extended Baseplate — Sits roughly one inch below the magwell on full-size grips, adding capacity without the bulk of an aftermarket extension.
9. Reliable Spring Tension — Heavy-duty internal spring maintains pressure from round one through twenty-one.
