    Q vs Griffin

    Published by Troy S on 20th Aug 2020

    I was going to buy a Q version of this but was honestly turned off by the marketing guy over there on instagram constantly shit talking other brands. He talks about Griffin alot though so i checked out their website and they also had the same adapter for my SIG rattler and supposedly make these products in house which means they should be really high quality (per Griffin customer service). Part came in the mail and looks flawless. I dont ever give 5 stars. So 4 is good.
