Kel-Tec P17 X300-A Key
$12.99
Allows you to put on a X300 and fit the recoil lug inside the P17 pic rail. This can be useful if you want to use your P17 in a holster that is meant for an x300.
NOTE! In my testing it can be very difficult to remove the light once on. You may have to unscrew the little side clamps to take the light off once installed.
