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.

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

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)

Bottom line: BUY IT

I have a 365 XL, and I was looking for a larger capacity magazine for my back up mag. (I carry concealed with the OEM 12 rd magazine so the pistol is darn near invisible), but wanted to give the 15 rd magazine a try and carry it as my second mag. Did not disappoint. Getting those last two rounds in are a bear until you get the spring broken in a little, but no feeding malfunctions to this point. Osage customer service was phenomenal. I was informed every step of the delivery process by Osage, which was great. 10/10 would order the mag again, and 10/10 I would order from Osage. Review by Chris (Posted on 7/13/2020)

Overall, I am please with the Sig Sauer P365 9mm 15 round magazine. They appear to be a very high quality product and work well. The spring is quite still and I can not even load the first round without a loader; the 15th round is really hard to get in. I am hoping that the tension eases up a bit as it it used. That said, I would buy more if I thought that I needed them. Review by Harry (Posted on 7/13/2020)
