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.

High Quality Magazine at one of the lowest prices in the Market

I am surprised at how well this magazine is made. And the free shipping when you order a $100's of Sig stuff makes this the best deal on the market. The quality of the way the magazines are made makes this the most durable magazine I have seen. The springs are strong and loading these mags will take a loader for the last few rounds, the springs are that strong. Review by Michael (Posted on 4/29/2019)

I ordered for the first time from Osage and I received these magazines within 2 days. Companies talk the talk and others just DO IT. Osage just DOES IT. Great service is no longer the norm but the exception. Kudos Osage.

I was a little worried that these were marked wrong but took a chance for the price and they are true SIG 12 round p365 mags. Easily $25 cheaper than anywhere else online and local stores are selling these mags for $65-75 if you can find them. Great shipping updates and the arrived much sooner than I expected. I will be ordering more soon Review by Travis (Posted on 4/20/2019)

I spent a lot of time trying to find the best price for the 12-rd mags, no one was even close to Osage County Guns.
Payment was easy.
Shipping was super fast.
Will look to Osage County Guns first going forward. Thanks

Perfect Magazine for Sig P365 for CC

Looked at a LOT of reviews for the Sig P365, and decided to get one, now I think the early issues are fixed. Then got two 12 round mags for it, as it's still small to use Conceal Carry with the 12 round, some may carry using 10 round to reduce printing, but I'm going to OWB and using 12, with the other 12 as backup. The mags are very well made, tough to get 12 rounds into at first, but break in a bit if you keep them filled. The magazines are expensive, but Osage had the BEST price, so made it better overall.

A must have if you have the 365. Should come standard with the 365. Add two rounds with minimal height, maybe an eighth of an inch longer than 10 round with extension. Review by 98UTVOL (Posted on 4/14/2019)

Best price on the internet I could find; I was worried the magazines would be scratch and dent or an aftermarket fake because they are so much more inexpensive than other places, but they are new Sig parts. The magazines make the pistol barely larger than a pocket pistol, can still easily be carried IWB, and my entire hand now fits comfortably on the pistol. I am glad I ordered these magazines, and glad I found Osage County Guns. Review by David (Posted on 4/11/2019)

I'm a California resident who utilized our "Freedom Week" to order standard capacity magazines. Everything about my purchase with Osage was perfect. Order acceptance, communication, shipment, and follow-up was exemplary. I can recommend Osage without hesitation. Review by Peggy (Posted on 4/11/2019)

Arrived way sooner than I thought. Buy here, it is way cheaper than buying anywhere else I’ve seen. Great product and great service. Only place quicker is buying in a local store, but that’s paying $20-$25 more per magazine! Review by David (Posted on 4/10/2019)

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.

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

Response Date: May 21, 2019

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.
