I purchased these thinking it was a metal product, per the listed specifications. I received them and found out they are plastic replacements that you can get for free by calling Kel-Tec for replacement parts and not have to pay $17 for more plastic junk. Very frustrated, I sent in a request for RMA so I can get the metal products I paid for.
Pros: none
Cons: Plastic
