Sig Sauer builds this factory magazine (part no. MAG-365-9-10X-COY) for the P365 Micro Compact, holding 10 rounds of 9mm Luger with an extended finger rest and a coyote-finished steel body. The finger extension adds grip surface on an otherwise ultra-compact frame, a common trade-off for shooters who want a fuller hold in exchange for a bit more length below the grip. Sig notes this magazine is not compatible with the P365X or P365XL, so it’s important to match it to the correct P365 variant. For Sig Sauer P365 Micro Compact owners, this handgun magazine is a dependable factory-correct spare.
