If you own a full-size P320 or P250 in .40 S&W or .357 SIG, this is the magazine Sig made for it. The MAG-MOD-F-43-10 is a genuine factory original part, not an aftermarket knock-off, and that matters when you're talking about feeding reliability. Stainless steel body with a corrosion-resistant blued finish, a heat-treated steel wire spring, and an injection-molded polymer follower all work together to keep rounds feeding cleanly and consistently every time.
The impact-resistant polymer baseplate is removable, which makes cleaning and routine maintenance a lot easier than dealing with a pinned or permanent base. It's a small detail, but one that adds up over thousands of rounds of range use.
One thing worth knowing: while this full-size magazine will physically fit in compact P320 and P250 frames, it will extend past the grip and not sit flush. It's designed for and works best in the full-size models. If you're running a compact, there's a different model number for that.
Having at least a couple of spare mags is just smart practice, whether you're shooting for sport, running drills, or keeping this gun staged for home defense. Load your spares up and rotate them out so you're not chasing rounds at the range when you could be shooting. This is sold as a single magazine.
It will technically fit and function in the compact models, but because it's designed for the full-size frame it won't sit flush with the grip. You'll get a noticeable extension below the baseplate. If you want a flush fit in a compact, look for the compact-specific version instead.
This is a 100% factory original OEM magazine from Sig Sauer, built to the same specifications as the magazine that came with your pistol. It's not a third-party or clone product, so fit, finish, and feed geometry are exactly what Sig engineered for these guns.
Yes. The .40 S&W and .357 SIG cartridges share the same case head diameter and overall length profile, which is why a single magazine works for both calibers. If you have a P320 or P250 with a .357 SIG barrel, you can run this same mag without any issues.
This listing is for a single magazine. If you're looking to stock up on spares, you'll want to add multiple units to your cart.
Yes, the polymer baseplate is removable, which makes it easy to fully disassemble the magazine for cleaning and inspection. Regular maintenance of your magazines goes a long way toward keeping feeding reliable over the long haul.
