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.

I ordered these on a Wed night and had them Friday. $15 less than most available online and in store. Took them to the range and was very happy with the capacity. It'll take a bit to loosen them up I'm sure, but a mag loader helped immensely. No feed issues at all. Definitely would buy from Osage again! Review by Merl (Posted on 5/22/2019)
Better for large hands.

The P365 is a really good quality EDC hand gun. Paired with the proper holster, the extra 2 rounds this magazine gives is a plus, but most of all it provides room to get about half of my little finger around the grip. Wish the mfgr. would consider people with XXXL paws. Just because our hands are large doesn't mean its easy to conceal a full size hand gun. Buy 2 of these at this price. Worth it.

These 12 round mags were the cheapest I found online. They arrived quickly and worked well. They aren't much larger than the 10 round mags with the extension. Review by Phillip (Posted on 5/21/2019)

Good quality, good price, quick shipping.
BUT
EVERY ONE STUCK AFTER THE THIRD ROUND.
A corner of the follower is ill shaped and sricks to the retainer cut out of the magazine body. If the rounds facing away from you this is the left front corner. Have to take the magazine apart and sand the corner slightly.
Also it is hard to load. Tough spring. Make sure every round is pushed in as far as it goes. If it is only slightly forward it may jam. The fit is very tight.

I'm a shopper, and Osage has the best price around and they do not gouge you on the shipping for a small item like this. These 12 rounders are very tight fit initially, and require a "break-in" period. I would suggest using the Maglula UpLULA Magazine Speed Loader, a real thumb saver for loading magazines. My other ones have already begun to loosen up. Review by Edward (Posted on 5/19/2019)

It did not come with a loader assist like my Glocks

And academy says my problem
I need some help please any ideas

Ordered 2 12 round mags for my sig P365. These fit my hand much better than the stock magazines. I have medium sized long finger hands. Without these the gun would not feel nearly as comfortable. Magazines appear good quality and functioned without issue. Review by Jonathan (Posted on 5/14/2019)

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?

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.

Rate the answer?
Are these the first edition 12 rd. mags where they had problems with, or are these the newer improved 12 rd. mags, working flawlessly?

Referenced product: MAG-365-9-12

Response Date: Mar 16, 2019

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.
