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.

THANKS for a great online experience...... I purchased 3 of the 12 round magazines for my P365 from Osage County Guns. I found their website while doing a quick search for the magazines and comparing prices. Once I saw their prices and availability I immediately placed my order. I'm totally happy with the entire ordering process, etc. Based on my own previous experience with many online orders I feel my order was processed and received in record time. The next time I'm in need of something they stock you can bet that I will be ordering from them again. Review by Kerry B. (Posted on 2/18/2019)

Last Friday I broke down and bought a P365. That is a saaweeet little 9mm. Well if you are a bit "Ham fisted" like I am (I wear XL gloves) you will certainly want the 12 round mag. Yeah, it gives you two etra rounds but it also extend that grip just enough for big hands to get that little bit of extra comfort to make the ultra conpact a nice little gripper. Well, I'm stingy with my money and Nobody comes close to this price. Its 100% SIG, it came to my door in less than a week for only $3.85 postage and at less that $35.00 for a $52.00 MSRP mag...You do the math. It was my first order from Osage County and they are my new friend! Thx, Osage. Brad
OH yeah, their MIL/LE price on the P365 was "danger close" to that of the Army PX discounted as it was on sale. Even with shipping and a FFL XFR Fee the gap as in a few single dollars. What a deal! I'll be checking their weekly ads! "Thumbs Up" Guys!

Haven't got a chance to go to the range and shoot it yet so i can't give a review is to the functionality of the mag, but from the looks and the feel of it, it seems to be of good quality only time will tell. As far as price goes Sig needs to lower the price of their mags so people can afford to purchase more of them. Review by ps (Posted on 2/14/2019)

It's a Sig mag: it works. Woohoo!

That said, I ordered it on a Sunday evening, it was shipped Monday and arrived Wednesday. Delivered for less than I could find it even listed anywhere (and that was before adding shipping or tax).

Got emails on status all along the way.

Will be a regular customer now.

I recent purchase the 12 round mag for my P365 from OCG. I found your website quite by accident. I saw your prices and availability and placed my order. I couldn't be happier with the service I received. Even placing my order over the weekend my order was received promptly
I will definitely order from you again

Better than the feel and performance of the new mags for my new P365, that I also bought from Osage, is the great service and quick shipping of the items that I received. I can't recommend them enough and planning to do more business with them soon. Review by Phil (Posted on 2/10/2019)

I ordered 3 12 rounders shipped quickly and all arrived in Original packaging. Upon opening them 2 of them looked they had been used, meaning a few slight scratches thru the paint showing on both sides of the mag. The followers looked new but never have I seen paint scratches on both sides of a new Sig mag. Weird Tim Review by Tim (Posted on 2/5/2019)

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.

Rate the answer?
is this 12 rd 365 sig mag oem

Referenced product: MAG-365-9-12

Response Date: Feb 7, 2019

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

Rate the answer?

Referenced product: MAG-365-9-12

Response Date: Feb 15, 2019

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

Rate the answer?
Will these be back in stock anytime soon and will the sale continue?Thanks,Artie

Referenced product: MAG-365-9-12

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.
