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.

The magazine worked great first time out. I’ve only had on range trip with it. I’m happy with the product and protruding magazine didn’t feel bad in my hand, looks a little funny/different than the lines of the 365. This will be more of a back up magazine for CCW and not the primary mag. Osage county has great products and stays on top of fast shipping. Every purchase I’ve made has been a good experience.

Mag arrived defective. Follower tilted so badly that it got stuck in the release notch in the body of the mag. As far as customer service, OCG couldn't have been better. Upon calling, the rep immediately placed a 3 way call to Sig Sauer and asked them to send a pre-paid shipping label. Without that intervention, I'm not sure they would have agreed to replace it so readily. Definitely impressed with OCG, and I will be a return customer. Hopefully the replacement will work properly and this was an isolated problem. Review by Mark (Posted on 6/20/2019)

I preordered the 15 round p365 mag. While the mag is somewhat of an odd fit for the small p365, it is a nice to have for backup or when using at bedside. OCG‘s service was perfect and price was best around! Review by Bruce (Posted on 6/20/2019)

3 shots in and something started rattling, dropped the mag and realized that the follower was stuck in the middle of the mag causing the bullets to just fall out once the mag was dropped, had to take it inside and pry the follower up with a screwdriver. More reports of the same problem from a group. This is not Osage’s fault but I would earn to be careful with this mag. I’ll be contacting Sig to see what they will do.

Not quite right

Okay so great price on these and got them pretty quick however, the mags need a little more development from sig. They always make things right so I'm not worried but apparently they don't have the follower for these dialed in just right yet. The spring is very tight I expected that but out of 4 I ordered 2 work fair if not a little gritty. The other two are sub par at best. The follower hangs on the left side so the last three rounds wont feed and then fall out. then you have to push something into the mag to release the follower from its perch at which point it immediately jams into the feed lips if you don't guide it up slowly. I haven't had them to the range as I just got them tonight. I expect with the follower hanging up so badly just during loading and unloading by hand that they will work well at all on the range.
