Gamo Magazine, C-15, P-27, P-430

Pros
a convenient cartridge to have when going out to the practice range, so having extra cartridges will help keep the fun going.

Cons
Perhaps a lower price is always good, as it's mostly plastic anyways.

The cool part is, if you wanted to, you can do 8 bb, and 8 pellet. A gimmick, I know, but still cool. Otherwise the mag functions exactly as it should. I've got 4 mags total for my p430.

Pros
Works as it should. Exact same mag as stock mag included with pistol.

Cons
N/a
