If you made the Sig Sauer P365 your daily carry handgun, a spare magazine is always a plus. This factory P365 magazine holds 15 rounds in a unique 1.5 stack designed specifically for the P365 and features an extension, so you can get a full grip. These magazines are also shipping with an additional baseplate to make them compatible with the P365 XL. Being able to hold 15 rounds of 9mm ammunition in a micro compact gun is a huge plus and having a few backup mags is even better.

  • 15 rounds of 9mm ammunition
  • Finger grip extension
  • Stainless steel follower spring

Works great

Bought this to go with my XL frame and love it.

Factory Part, Fast Shipping!

by -

I carry a P365 everyday, and I purchased this as my spare mag. I got it shipped fast from Primary Arms. Awesome Company, and amazing products at competitive prices! When you combine this 15rd magazine with your P365, the game changes drastically, it feels like a full size grip. Definitely get yourself of these.

Better than Expected

Feeled my needs or what I think my needs will be, if the occasion should ever arise... I purchased three 15 round clips, I'm happier than pigs in $#!&...

P365 15 round mag

Sig 15 round mag came with both sets of floor plates (base and XL). Works flawlessly!!! Only down side I find is the open back on the floor plate leaving the flat of the mag against the hand... should have been filled to match the grip.
