When I bought these mags they were $36.99 where everyone else is charging right around the standard $44. This is a hell of a deal at this price for sig factory magazines. They also ship very quickly which I appreciate as I’m spoiled to Amazon Prime. Review by Christopher (Posted on 2/20/2020)

Product Questions

Product Questions

I’m trying to make sure it fits the p250 40 caliber compact before I buy

Referenced product: MAG-MOD-F-9-21

The 21rd magazine will fit in the P250 .40 grip module but it is a 9mm magazine so it will not accept .40 S&W ammunition. If you have a 9mm slide and are running 9mm ammo you're fine. Full size magazines will fit in compact (and sub compact) grip modules but there will be a gap between the grip shell and the magazine floor plate / extension (in this case).

Rate the answer?
Are these the new magazines with the "SIG" marked base plate that fits in the P320 Carry or the older "Sig Sauer" base plates? Thanks

Referenced product: MAG-MOD-F-9-21

These are the updated design floor plates and fit in the X5 and X-Carry and are marked Sig.

Rate the answer?
I have a sig p320 carry. Will this 21rd mag work for my model as well.

Referenced product: MAG-MOD-F-9-21

The MAG-MOD-F-9-21 will work in a P320 Carry grip module.

Rate the answer?
will thee fit Xgrip carryI'ordered tree that are on the was and wedbsite didn't specify wheteher they are older mags labeled Sog Sauer that don't fit. If they are older ones can I return them?

Referenced product: MAG-MOD-F-9-21

Response Date: Feb 7, 2019

Our mags are the updated design with the round Sig logo and they fit the X-Carry / X5 grip modules.

Rate the answer?
Will this magazine work with the p320 x compact?

Referenced product: MAG-MOD-F-9-21

Response Date: Sep 24, 2019

This magazine will work with the X-Compact but there will be a gap between the bottom of the grip and the magazine's extended base.
