Genuine Made-In-USA Sig Sauer Magazines for the P320 and P250 series of 9mm firearms.

Generally, higher capacity P320 magazines will fit smaller P320 grip modules / pistols; however, some P320 variants do not follow that pattern (i.e. the P320 X5 Grip Module will not accept standard full size magazines due to their extended magwell). Be sure to check fitment and function with your combination.
