This is a factory Kel-Tec P17 .22LR 16-round magazine.
I haven't received them yet
If you rate the fun factor of a pistol based on “smiles-per-dollar”, the Kel-Tec P17 is right up at the top. A few things that put it there is a reasonable capacity in such a compact, lightweight firearm, easy loading, and its reliable functioning. The simple, robust, and inexpensive magazine design is certainly a major player in these factors, and Mag Shack has a great price and quick shipping on the OEMs.
Ordered mags and had them inside of a week. Very reasonable prices but extra happy with the shipping
This was the only place I found the mags. They were priced well, delivered promptly, and worked great. Will probably order a few more. Thanks.
