VFC Stark Arms SA320 Gas Magazine

Two lengths, one pistol. The twenty-two round magazine seats flush with the bottom of the grip frame, which keeps the gun holster-friendly and the profile clean. The twenty-six gives you four more rounds at the cost of sitting proud.

The flush magazine is built around a metal alloy housing with high-density polymer feed lips and base plate, and VFC quote it at roughly 230 grams empty, which is close enough to a loaded service magazine that reload drills feel right.

Published fitment runs wider than the SA320 itself: the same magazine is listed for the VFC-built P320, M17, M18 and XCARRY pistols, which makes it a useful spare if you own more than one of them.

Specifications

Good to know before you buy

The two capacities are the same magazine family at different lengths. If you carry in a kydex holster with a tight mouth, the flush one is the one that will not fight you.

VFC release a full material and weight breakdown for the twenty-two and almost nothing for the twenty-six, so the heavier cells in the table above apply to the flush magazine only.

Frequently asked questions

Will these fit a Sig-branded P320 from another maker?
The published fitment covers VFC-made P320 pattern pistols. A P320 from a different factory is a different magazine well and we would not promise it.

Which one should I buy?
Flush twenty-two for carry and holster work, extended twenty-six if you would rather have the rounds and do not mind the overhang.

Can I use CO2?
Green gas is specified. Stay with it.

Does the twenty-six round weigh the same?
No figure is given for the extended magazine, so we have not guessed at one.
