Technical Tuesday: Low Bore Axis

This week, we are looking at the bore axis of different polymer frames as it compares to the MR918 frame. One of the main pieces of feedback we are hearing from customers who have purchased the MR918 is how flat it shoots–what that means is there is not a lot of muzzle flip during firing.

One of the main differences as you start to compare polymer frames is the height of the bore as it relates to the hand. If you look at a Walther P99 or a Sig Sauer P320, it has a relatively high bore axis, in that you see there is a lot of slide and a lot of beavertail between the hand and the sights. If you then compare that to the MR918, you will see there really is not a lot of slide or beavertail between the hand and the sights. The location of the bore relative to the hand on the MR918 is very low–that is the principle of low bore axis. When the gun is firing, it doesn’t get the same amount of leverage in your hand. The principle of low bore axis means that you will get less muzzle flip.

What did we do to achieve a low bore axis when designing the MR918? A lot of the things we learned before designing this frame came from our time in the custom world, doing customization packages on Glock pistols. Through the process of that, we really learned what works well. If you look at how the bottom of the trigger guard is shaped, how high and relatively flat the beavertail is, how we have narrowed the frame and recontoured it to allow it to sit really low in your hand. We have also removed material from the trigger well, so if you have short fingers, maybe a young shooter or a female shooter, you will have an easier time of reaching the trigger on the MR918 than on other polymer framed pistols out there.

Our goal from the very beginning in designing this pistol was to control recoil, to bring the very best out of the custom world, and put it into a production gun.

So, go get your hands on one and we are confident you will feel the difference and you’ll be aware of that low bore axis on the MR918.
