Frequently Asked Questions
Are Sig P250 and P320 magazines interchangeable?
Can I use the same magazine for my P250 chambered in .40 S&W and .357 Sig?
Yes! Factory Sig P250 magazines are designed to work with both calibers. However, a couple of aftermarket options don’t reliably feed both, so we recommend confirming before purchasing.
