Are you shopping for P365 XL 12rd Magazines? These magazines now include the second floor plate that makes them compatible with both regular P365 pistols as well as the P365 XL!

This is a brand new OEM Sig Sauer P365 9mm 12-Round Extended Magazine.

Sig Sauer designed the P365 magazine first and then engineered the firearm around the magazine. The firearm and magazines are extremely small. Because of the size of the magazine and capacity, the springs are stiff.

Please note that these magazines are extremely difficult to load. We have received a number of complaints and inquiries from customers that believe the magazines are defective or have incorrect springs. The mags are not defective but due to the very compact nature of the magazines, the springs are very tight when new. The magazines will loosen up some over time with use. Using a mag loader will help as well.

Also note that we have had a few inquiries from customers regarding marks or what appears to be wear on the magazines. We have observed that quite a few of the magazines have minor marks that appear to be from testing. We called Sig they confirmed they do batch test magazines that could account for some of the marks on the magazines.

Frequently asked questions about the P365 12rd magazines:

Q: Your website says these are in stock. Are they really in stock? A lot of other dealers say they are in stock but then after ordering it turns out they are not in stock.
A: If our website says they are in stock, they are in stock. It is really sad that it is necessary to even have this as a FAQ item but we receive multiple phone calls every day because so many other dealers suck at what they do (or are drop shipping from a distributor) and don't really have them. This often happens with drop shipping because the dealers list inventory at their distributor and they really don't have a handle on what they have listed on their website. We stock all of our inventory in house and don't rely on distributors to fill your order after you order it.

Q: How are you selling these so cheap? Are they real Sig OEM magazines?
A: We buy these magazines by the pallet and that allows us to pass on savings to you. These are OEM Sig Sauer magazines and not a third party knock off magazine.

Q: Is this compatible with the P365 and P365XL?
A:
Yes. Sig Sauer is now shipping these magazines with a flush-fit floorplate for the P365XL as well as the extended floorplate for the standard P365.  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 extension piece is only for the standard P365.

Q: I have a P365XL.  What do I do with the 2-piece basepad?
A:
Nothing. The 2-piece pad is only for the standard P365 and is not used on the P365XL.  The magazine is the identical to the 12rd magazine that ships with your XL when configured with the flushfit XL floorplate Do not attempt to stack the P365 floorplate on the magazine body and insert it into your P365XL.  You will fail to lock the magazine into your gun and it could fall out and hit your foot.  That could hurt.  We don't want you to get hurt.

I purchased 2 mags from Osage County Guns because they were one of just a few online retailers that had them in stock and they had the best price as well. I placed my order on Tuesday and the order was in my mailbox on Thursday. Quality was as expected and it took less than 5 minutes to replace the XL base plates with the provided spacers and plates to fit my P365. Function has been flawless. I will be an Osage County Gun repeat customer! Review by Mark (Posted on 2/20/2020)

Ordered two 12-rd mags for the P365/P365XL. They were exactly as advertised, brand new, in SIG commercial packaging. They had the floorplates for the XL installed, but the P365 floorplates were included. A quick press of the tab to slide the originals off and some quick work to put the P365 plates on (has the finger rest/spacer), and all was done! Easy! Review by Kevin (Posted on 2/16/2020)

Osage has as good of a price as anyone on these mags. They were just what I needed for work and they shipped fast. I put a XL grip on my 365 and needed 12 round magazines where I could convert it to the flush base plate. These come with both.

Thanks!

Typical sig quality magazine. The spring is strong and feeds reliably. I had to replace the base plate with the provided extended plate to fit my P365, as I don’t have the P365XL. It took a couple of minutes to decipher, but looking at another 365 mag clarified.
Osage shipped quickly and kept me posted on the progress. They also had the best price I could find. I’m very happy with the entire experience and will be back to Osage for future purchases.

Hello do these come in individual Sig Sauer boxes or are they sold in Bulk? Tim

Referenced product: MAG-365-9-12

These mags come in Sig's OEM packaging meaning their retail packaging. That is normally a box with clam shell but some of their other mags come in Sig logo bags. I believe these specifically, as of this response, come in the box with plastic clam shell.

These do not yet include the XL base. You can contact Sig and we've been told that they will send the base to you. In the future they may include it with the magazines.
