Multiple Role Pistol Online – MR918 – Shadow Systems

Meet the MR918 Combat.  This is our no-nonsense answer to a fighting pistol but includes features normally found only on the finest custom guns.

The MR918 name comes from the idea of creating a true “multi-role” pistol.  The size and operating system of our online multiple role pistol is inspired by the Glock Gen4 G19 model, but many aspects have been redesigned.

The frame has been in development for 2 years and is 100% a Shadow System design, and not a rebrand of another frame already on the market.  The frame makes use of new manufacturing techniques to wrap more texture around the curves of the frame and put grip in places not normally seen on production guns.

  1. Rick H.

    I’ve only had this masterpiece a few days but it’s become my absolute favorite pistol. Phenomenal point of aim. Ergonomics second to none. I’ve always been a S&W M&P guy due to comfort and natural point of aim…then I held the MR918 Combat. Didn’t think I could find better, for me, ergos or a better more natural point of aim. The fit and finish is impeccable. The flat trigger is fantastic. I can’t recommend this pistol enough. Incredibly flat shooter. I’ve told every one of my buddies about it. They are now looking into acquiring a Combat or Elite. This pistol truly is The One. Conceals perfectly and comfortable to carry. Looking forward to future purchases. Next up, the Elite. Big thank you to Shadow Systems and your team. My other pistols are now gathering dust in the safe.

    This by far is the best gun I have ever bought
    And I’ve been shooting 30 years and have tried every company out there. Still a glock fan but this mr918 even kicks glocks ass. Great product guys !!!!

  3. Buddy Haarman

    Awesome work of art for a pistol. Couldn’t be happier unless I owned two more. Really reliable and consistent at the range. I put between 500 to 600 rounds each time I am at the range and have never encountered a problem. Customer Service is excellent. VP of Operations Jennifer Nasseripour personally contacted me about an order and got it out sooner than expected. I will definitely be purchasing more handguns and parts from Shadow Systems.

  4. Russell Kolpin

    this has been a great firearm so far . im only at 500 rounds in so far. i really like what you have done with what i thought was a poor a poor design and i thought i would never buy again (glock) and really made major improvements. this gun just fits, functions, and performs this thing is great. and the fact that when you call you get a real person who works with the product, not a call center and they call back. great people i will be checking back for new products

  5. Kerry Hoover

    I bought my MR918 about 2 months ago now and it has become my favorite carry gun. Been 100% reliable and everyone i have let shoot it now wants one. I looked into customizing one of my Glocks and this ended up being the better route both time wise and cost wise. the pistol came with every feature i like

  6. Ryan Doeckel

    Shadow systems makes a fantastic product. Have had the MR918 for a year and a half and put over 12,000 rounds on it. All still original parts (I might need to change some springs/extractor soon, but that’s to be expected). I have used it primarily for IDPA and staged as a home defense weapon with a light on it. Trust it with my life and plan to buy the MR920 soon.
