    Evan Faucette

    Feels great, built sturdy, looks purdy!
    Shoots very well with no hang-ups. Easy to control, a child can hit the 3″ plate at 50 yards.

    Good Product And very accurate I felt like a police shooting my Glock 20 Gen 4. I had A ETS clear Magazine 30 rounds.

    The MCK is fantastic!
    The only problem I have is the shoulder arm does not latch properly and flys open.
    BUT… Love it and will order more product when I can.

    Everything works great except the spare mag well won’t securely hold my 30 rnd Kriss Vector mags. The plus is my small frame wife loves shooting my Gen 3 Glock 21 now. She liked it so much I had to buy her a Gen 4 21C to permanently reside in it.

    Fantastic fit and finish. I will likely round some of edges at a couple of points as they are very sharp. The short stabilizer arm is perfect for firing in full gear/vest/armor; even with my long arms. I will likely be purchasing an MCK for the G48 I’m the future. Handy system you all have created, and worth the wait. Also, the head of customer service deserves a raise :ok_hand::skin-tone-3:

    I am amazed at how this product can turn almost any handgun to a more stabilized firearm. It is small but can work with almost any enthusiast. The overall design is optimal for use, with the added thumb rest plus if your handgun has an upgraded grip on the hangun you can have a firm grip at all times. The extra magazine holder is optimal for many uses and being in the front makes the reloading process a breeze. One of the downsides from what I read is while using the pop up sight it tends to shoot up and to the left which is why I decided to go with the red dot sight to begin with. The second is the way the hangun fits in takes practice but if you watch a couple of videos or practice it shouldn’t be a bother. The last and to me an important one is the stabilizer holder once you fold it it tends not to stay in place, it’s not a big problem but could be slightly better. You do have to debur all major edged to ensure a smooth feel when handling. The MCK conversion kit is a great product that won’t break your budget with easy to use and install add on for any skilled user. The design and color scheme is great because you have a variety of options to make the MCK conversion kit look and feel like YOU own this product. Thank you MCK for solving the issues I had and making such a cool product for everyone.
