Product Details
Sig Sauer, Magazine, 9MM, 17 Rounds, Fits P365 X-Macro (also comes with grip extensions for the P365 and P365 XL), Black, New in Box
Not only the correct mag for your X-Macro. Sig includes two sleeves that allow for use on the standard P365 and the XL. This is the OEM SIG extended capacity option for all P365 9mm pistols.
I have no idea what type of mad science went into squeezing 17rds of 9mm into such a small magazine, but Sig did it, and they work! This is not a magazine I would trust to the aftermarket (though none currently exist anyway). Stock up on OEM while you can.
SIG part number: 8900804
Condition: New in box
