Were you shocked that the P365 holds 12 rounds with an extended magazine? Well hold on, because now you can fit 15 rounds, that's right FIFTEEN ROUNDS! This is an OEM Sig Sauer Magazine guaranteeing the same reliability as your other magazines. This magazine is compatible with the P365 and P365 XL. It includes an second floor plate for use with the P365 XL. We have seen either floorplate preinstalled from the manufacturer. You may need to swap out the floorplate depending on which gun you have (XL or non-XL) and which floorplate Sig Sauer installs at the factory.

The photos below show the 15rd magazine in a P365 XL and P365.

Sig P365 XL and P365 with 15rd Magazines

These magazines will be stiff and some customers find them difficult to load. We recommend using a Maglula Uplula magazine loader.

Great product, fits perfectly, factory oem part. Cant beat 15 rounds in such a tiny package. Fast shipping, kept me informed of all updates. Cheapest price here at Osage, also bought a P320 trigger and P365 trigger. Everything was exactly as expected. Excellent overall experience, I’ll definitely be back. Great one stop shop at great prices. Review by Matt (Posted on 1/15/2021)

The included 10 round clips that came with the P365 are ideal for concealed carry (my primary use), but I wanted the 15 round clip for home defense. I ordered two, because I like to have a backup and because I couldn't believe the price ($5-$10 cheaper than anywhere I could find). I am pleased to say I received both clips in less than a week, well-packaged and in pristine condition. I couldn't be happier with the service I received or with the product. I've already recommended Osage County Guns to a couple of family members who own the same handgun. Review by Tyler (Posted on 1/14/2021)

SIG Quality magazines for the P365. Osage County actually had them in stock and for a cheaper price than anyone else. Sig magazines are pricey, however they are of exceptional quality, will work perfectly, and last decades. Review by Theflipguy (Posted on 1/10/2021)

Ordered this mag from OCG and 2 days later it was in my mailbox! I ordered this for my P365XL. It came with (2) base plates and the one pre-installed must be for the standard P365 because it didn't fit. I swapped out the base plates in a matter of seconds and the mag went in the gun like butter. Thanks! Review by Paul (Posted on 12/23/2020)

SIG factory mags are too expensive, but OSG has the best price for the 15-rders. They work fine in my XL, no complaints. UpLula necessary to load fully. Review by the perfesser (Posted on 10/3/2020)

Sig Sauer P365 15 Round Magazine

Quality
Price

This magazine is the usual superb quality part you would expect from Sig Sauer. I purchased it mainly for range work but I prefer the 12 round version for CCW. I am sure the 15 round could be used as CCW but the print would be a bit larger. Nonetheless it is a well designed, perfectly functioning magazine that makes the P365 a 16 round pistol in a very compact size. As always I was very well pleased with this, another transaction with the fine folks at Osage County Guns. Review by Jerry A (Posted on 9/29/2020)

A must-have for every P365 owner. I usually carry three 12rd mags on me at all times, but having this as an option is no gimmick. Though printing is slightly more probable with a more snug fit shirt IWB carry, I can’t think of a reason to not own at least one of these as another tool in the toolbox. As with many reviews I read before ordering, I found online contact with the people at Osage to be almost immediate, they answered my questions confidently, and shipped almost as fast...two days later, bam - delivered. Thank you, OCG! I’ll be back! Review by 4PHUNK (Posted on 9/29/2020)
