Technical Tuesday: What does it all mean? MR? DR? Combat? Elite?

Today’s Technical Tuesday, we are discussing the product line. What is MR? What is DR? What about Combat and Elite? How do I pick what’s right for me?


There are currently two frame sizes. The MR-sized frame, which is a 15+1 9mm, and you have the DR-sized frame, which is a 17+1. The DR would be considered a true full size pistol, while the MR would be more in the compact-sized handgun.


The MR stands for Multiple Role. The 15+1 9mm sized gun is truly multipurpose–you can use them a duty guns, you can EDC them, it’s a great home defense gun. This is a size class that covers a lot of bases and is still very shootable.


The DR stands for Duty Role, and that’s who we designed it for. Shadow Systems now has a growing presence in the Law Enforcement market, which we are very excited about. The DR frame is geared towards those with larger hands, or appreciate the fuller capacity, or just want a full size pistol with a longer sight radius.


The MR and DR distinctions really just refer to the frame size. Now, let’s talk about the pistols themselves. We have the MR920; 15+1 guns with a standard 4″ barrel–a compact handgun. The MR920L (Trevor’s favorite) has the full length slide on the 15+1 frame. The grip size is the same, but the sight radius is longer and the slide is longer–why? Well, most folks will tell you that the hardest part of the gun to conceal is the butt, so the longer the grip is the more it will print under your clothing. So, we added that longer slide to make the gun more shootable. The MR920L shoots like a full size and carries like a compact. Then we have the DR920, which is the full size handgun.


Now let’s talk about slides. When it comes to slides, we have basically three types of slides that go on any of the frame sizes, whether it’s MR or DR; the Combat, the Combat Optic, and the Elite. The internals of the pistols are the same between all three slide models. We have the Combat slide. The base Combat slide just has iron sights, regular dovetail sights with a nightsight front. The Combat Optic is that same slide that also has our proprietary optic cut. The Combat slide does not feature any window cuts. It does have front and rear directional serrations, but no topside serrations and no window cuts. Next we have our Elite slide–all Elite slides feature our optic cut, which fits most optics on the market with ultra long and ultra strong screws. The Elite slide features the front and rear directional serrations as well as topside directional serrations and a weight optimizing window cut.


We also talk through the different options and features and how to choose the pistol that is right for you.

    Any plans to improve on the G43X MOS?
    I’d really like to see a 920 Sub compact OS 15+1 become another option. I like what you’ve done on the MR920. It’s my first poly. Usually shoot the CZ P01.

    Please make a g43x/48 elite. The slim frame fits my hands much better and with the shield mags would be IMO the perfect pistol. Even though your grip is far better than a standard glock, it still has the “block” feel. The slim line addition could add alot of potential customers.
