This mag is a bit stiff to get the rounds all in at first so be patient load about 7. Then the next day load 3 more. Leave them loaded for a week then you won’t have issues loading all 15. The mags are great for extra ammo carry Review by Rene (Posted on 6/23/2019)

This mag fits nicely and was hard to load the first time. I let the full mag sit for 2 days than ran it and it was flawless and easier to load after that. The extended grip only protrudes from my hand about 1/2 inch and will not affect my shooting style at all. Great backup mag for cc. Review by Vince (Posted on 6/23/2019)

My mags just arrived. They are perfect. No defects or functionality issues. My order arrived on time. This was by far the best price I could find anywhere. Osage County Guns now has another loyal customer! Review by Roger (Posted on 6/23/2019)
Doesn’t match grip profile
Price

Of course I’m a fan of more capacity, but the back of the magazine/base plate is flat. It does not extend to match the profile of the blackstrap. So when installed in the P365 it does not reach the backstrap making the grip somewhat awkward. Matches profile in the front. Review by DanielJD (Posted on 6/23/2019)

I didn't wait too long for the pre order to come in and Osage shipped it fast, like always. We to range with 14 eds in it because I don't own an Uplula. It worked 100%. Can home and took it apart pretty easy. It was. a bit dirty iinside the mag body. I lightly Flitz 'd the spring. Finally , just barely loaded all 15 by hand. I'll keep it loaded until next range time. Hope its easier to get all 15 in next time. I'm glade to have a 15 round mag for my P365. Review by Fpav (Posted on 6/23/2019)

I tried something on these 2-15 round mags . I'm leery spraying any lubricant inside the mag when there is going to be ammo loaded in it especially for serious business ammo.. I definitely don't want to chance lubricant to penetrate into the primer.

I took both of the magazines apart. I took some fine 400 grit wet and dry paper and gently hit the 4 sides of the followers then finished with some Scothbrite. I noticed there was an excess of polymer where the mold halves met. Wasn't much but I thought it might be enough to cause the follower to hang up.
I re-loader the mag that had given me a hard time and it worked like you'd expect them to no hesitation or hang up.
I did notice the one magazine spring seemed to be distorted (a slightly twisted appearance) compared to the other mag spring.. I won't know for sure until I make a range trip.
I did change to the smaller mag floor plate on the one mag.. Has the same length but doesn't seem quite as bulky as the larger floor plate.
I hope this will help someone that is having a problem with the follower hanging up.
It took me about 10- 15 minutes to do both mags. Watch that spring it shoots out like a rocket if you let it.

On the first attempt to load the magazine the follower stuck. I sprayed a quick shot of "One Shot" lube in the mag and released the follower. It works perfectly now. Review by Dick (Posted on 6/21/2019)

OCG is the go to for your P365, best prices, best selection.

Now about this mag. This is my spare mag that I carry everyday. Does it look as good as the 12 round, nope, does it fit your hand as well as the 12 round, no again. Who cares? If I have to pull this mag out to reload, I’ve gone through 13 rounds already and life has become challenging at best. Having another 15 rounds of defense ammo at the ready is worth not having the most ergonomic spare magazine. I’m waiting for the after market 30 round magazine for this little beast.

I have mixed feelings about these new Sig P365 15rnd magazines.

I bought 2 of these 15 round magazines. As others have said I won't using them for carrying. I only loaded one of them and I had a hard time loading a couple rounds with the follower. I'm using Hornady Critcal Duty so it's not cheap ammo and a Uplula mag loader.
I tried one on just to see and that mag extension sticks out like a sore thumb.
I could change the extension with the smaller ones supplied but that defeats the purpose of buying them.
I'm going carry one of the 15's in my Sticky holster magazine sleeve and use either the 10 or 12 round mags for carrying.
I am hoping if Sig discovers there is a problem with the followers they will offer a fix or replacement. I see I'm not the only one that noticed the follower issue.
I'm not saying I regret buying them but probably should have waited to make sure any bugs were worked out.

Returned the Magazine

I carry the P365 with a 12 round magazine everyday, love it, and had hoped the 15 round mag would increase my carry by three rounds with only a slightly larger grip. However, the design of the magazine makes the gun look and fell awkward. The magazine also looks like, it could’ve been cosmetically finished better on it’s backside. Perhaps it looks better in the P365 XL or just as a backup magazine. Certainly not for primary carry in the micro P365. Review by Aturnknee (Posted on 6/20/2019)

The 15 rd mag is an excellent option to carry as a back up, or to have in place overnight while sleeping. I would recommend putting a light coat of silicone on the inside of the mag case and then loading and unloading the magazine a few times to help break it in before actual range use. I'm happy with the added options for this handgun. Review by C. B. (Posted on 6/20/2019)
Feels half done

OCG shipped this fast as usual.
The magazine feels half tonight out. The extension is a bit ugly compared to the 12 round magazine, not that it matters so much what it looks like.
The fit is a bit soft so it will rattle in your hands and flex when you shoot it, but what bothers me the most is that the back of the extension is just flat, so it sits very weird in my hands. I prefer the fit of the 12 round, but am happy to have 2 15s sit on my belt.
