Curve has been a bit of a laughing stock since the news came out so it had to be mentioned. Here you can see the left side of the gun. Very simple and magazine is not drop-free, and there are no magazine releases. You have to grab both sides of the magazine at the bottom and pull it out.
Right hand side has clip for holstering. You can see the light button near the front.
The Curve definitely lives up to its name with this vewi from back. The grip really doesn't feel that bad in either hand. However there is no telling how this will feel like when you actually shoot the gun
