P365 Micro Compact 15rd 9mm Magazine is rated 4.1 out of 5 by 382 .

Rated 1 out of 5 by SigShooter23 from Poor design I was very disappointed when I took this mag to the range. Sig definitely dropped the ball with the grip design on this one. At first glance, like everyone else has stated, the thing looks horrendous. Then the fact that is has no back side to it like the base plate of the 12 round mag, makes it uncomfortable to shoot because the bottom of your palm gets pinched with the gun frame. I hope Sig Sauer is reading all of these reviews and is trying to come up with a better performing base plate for this magazine because its clearly is not meeting the standards in the 2A community that we all expect from Sig.

Rated 3 out of 5 by MattMan from You can do better I recently bought a aftermarket magazine extension for another SIG and it was great. So when I saw one for SIG by SIG I had to buy it. While it works it it seems like a garage modified magazine. Feed is poor when loading the spring does not feel right and push feed locks up sometime. While unloading is fine it’s a SIG after all. I like the moulded base that locks in tight with out gaps. The the shape of the base is ok but could be better. With all the plastic molding and laser cutting out there I expected too much. The components do not seem like a design build but what can we make with what we have.

Rated 5 out of 5 by Rick NC from The 15 round mag. Hopefully, I will never have to use this mag for anything but, for time at the range. As a retired K-9 handler for both military and police. I was excited when I bought my 365 Sig. That weapon came with the standard two ten round mags, and of course when Sig came out with the 12 round I had to have that to add to my back up. Then when you would think Sig could go no further guess what ..a 15 round mag comes out...WOW ....tight when loading, clean feeding ...and peace of mind knowing as a Disable veteran, I have the back up power to complete me and my K-9 partner...thanks Sig.. never stop being inovative and practical with your life saving ingenuity

Rated 2 out of 5 by KoltTCU from Great capacity, not great looks or feel Sixteen rounds is nice but the back of the mag is flat and looks absolute silly on the gun. The feel doesn’t feel good either because the bottom of the hand presses against the mag and feels funny. They tried double dipping this mag with the 365 and the 365 XL and failed massively. Probably the worst accessory they have come out to date. I like the capacity and if they hadn’t have been $35 I would not have bought. Hopefully they come out with a back plate that’s textured or recall it because I don’t imagine anyone is going to be completely satisfied with it.
