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.

Sig magazine is exactly what you'd expect from Sig.

OCG is the real hero here, not only did they ship fast and send email notifications along the way, they included the floor plate to make this mag work in my XL. All for a great price!

The 12-round magazine makes the P365 fit my hand a little bit better, plus 12-rounds in a 9mm pistol that size is fantastic. The spring is very stiff and getting 12 in without a loading tool was a challenge.
Overall this was a good purchase.

I like the magazine options for this gun. 10 +1 can be carried in my pocket or, when wardrobe allows, now 12+ 1 IWB. Osage had the best price and got my magazine to me quickly. You'll be happy with both.

Osage had the best price, but SIG is pretty proud of their magazine at this price point (personal opinion). 4 star "value" was for that. 5 stars for Osage County Guns.

Ordered the 12-round 365 Sig Sauer magazine. It came packaged in the Sig Sauer logo Packaging. What can I say, it's well made, great customer service. When I received the package within 10 minutes I had it field with my ammunition and ready to go. Great experience all around. Review by Thomas (Posted on 10/31/2019)

If you want the extra length for that pinky, get it. Love this thing, will order more. The 15-round was a little longer than I liked but this 12-rounder is perfect. Pricey, yes...but well worth the comfort. Review by SST (Posted on 10/30/2019)

I ordered two 12 rd mags for my Sig P365. They were the absolute best price I could find and arrived two days after I placed my order. The freight charge of $8 was the best also. I am very happy to have found OCG and plan to purchase many things from them in the future. Review by Ed (Posted on 10/29/2019)

We checked several online options to purchase this 12 rd magazine and Osage beat all the rest in quality, shipping options, and best of all - lowest price! With tax & shipping combined with product cost, it was still less than just the cost of the product on other sites. Review by Karen (Posted on 10/28/2019)

Product Questions

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.

Rate the answer?

These are Sig Sauer brand magazines in Sig packaging. They are not third party mags.

Rate the answer?

Unfortunately due to Maryland's laws, we're unable to ship magazines with capacity greater than 10rd into Maryland.

Rate the answer?

As of this response, we've still got over 700 of these magazines in stock with additional shipments coming. The pricing will vary from time to time but we encourage you to order now if you want to take advantage of the sale.

We aren't aware of any widespread issues with the 12rd magazines but these were received from Sig Sauer within the last 45 days.

Rate the answer?
I have the P365 in coyote tan, do you have the 12 rounds magazine in this color?

Referenced product: MAG-365-9-12

At this time Sig is not offering Coyote colored mags. We've been inquiring frequently and if they become available we will place an order and stock them.

Rate the answer?
Will this 12 rounder fit the 365 XL

Referenced product: MAG-365-9-12

This won't fit the P365 XL. We're expecting Sig to release updated magazines soon or floor plates to convert these magazines.

We will have Coyote P365 magazines in the next 30 to 60 days as well as Coyote grip modules. We will have all four variants of the magazines (10 flush / 10rd extended / 12rd / 15rd).

Referenced product: MAG-365-9-12

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.
