Frequently Asked Questions
Will this magazine work with all Sig Sauer P365 variants?
This ProMag magazine is designed specifically for the standard Sig Sauer P365 chambered in 9mm. It is generally compatible with P365 variants that share the same magazine well, but fitment with the P365XL or P365X may vary. We recommend verifying compatibility with your specific model before purchasing.
Why does this magazine have a 50-round body but only a 10-round capacity?
This magazine features a California-compliant block that permanently limits its capacity to 10 rounds, even though the physical body is sized for 50 rounds. This design meets California's magazine capacity restrictions while maintaining the magazine's original exterior dimensions and feeding geometry.
Is the ProMag P365 magazine reliable enough for concealed carry use?
ProMag manufactures its magazines in the USA using heat-treated chrome silicon wire springs and quality-checked assembly processes, making them a solid choice for range training and everyday carry. As with any aftermarket magazine, we recommend running a full break-in period at the range to confirm reliable feeding with your specific ammunition and firearm before trusting it for defensive carry.
