Technical Tuesday: Common Customer Service Questions about the MR918

This week, we’re going to answer the top three customer service questions we’ve received so far about the MR918.

The first is Assembly and Disassembly:
1. People seem to have a tendency to pull the slide back a bit too far when they are disassembling the MR918. It may be that some folks aren’t used to the aggressive serrations on the MR918 and that allows for the slide to go back a bit further than you need during disassembly. When disassembling, your start point should be gun empty, no magazine, trigger to the rear. You only need to pull the slide back 1/16 of an inch, a really tiny amount, then pull down on the slide lock to release the slide from the frame.

2. Because of the way we’ve engineered our barrel to locking block and slide to slide rail fit, our top end is just a bit tighter of a fit than other polymer pistols. Therefore, some folks have found, especially on a new gun, that the lugs will hang up a bit on the slide lock as you reassemble. If you get this issue, just give the slide lock the tiniest nudge downward and the slide will ease back onto the frame.

The second question we’ve seen a bit is “how do I get the backstraps off?” They do fit nice and tight on the dovetail, so let’s take a look at how to do that. First, be sure you’re using the tool that comes with your pistol. You will push on the pin from either side and slide it out. Once you remove the pin, you really do need to use the palm of your hand or thumbs to push it off the dovetail. It does take a bit of a push to get started, but once it gets started it comes off quite easily.

Lastly, the magazine well. We’ve had one customer break a magazine well plug when they installed it; we think maybe the plug was in upside down. When you put the plug in, you want to be sure it sits nice and flat into its recess. If it isn’t seated flat, you may break it off. So, once the plug is set, the magazine well hooks on from the front first, then it will snap into place int he back. At that point, you can reinstall your pins. The longer pin, that was already in the gun, goes into the backstrap side and the shorter pin from your kit goes into the bottom. Just a side note, as we’ve been asked this a bit, our magwell system is a proprietary system that is specific to our MR918 and will not fit any other after market magwells in the market.

Those are the top questions we’ve heard from customers so far, but if you have a different question we haven’t answered here, drop it in the comments or drop us a line at 469.458.6808.

    Hello! I recently purchased a MR918. Love it but wanted to know if the mag release is compatible with glock, and what gen?

      Hi Blake!
      The MR918 is going to be compatible with Glock mag releases. Look for Gen 4 parts.

    Hello here, I was wondering if a non adjustable recoil spring was available for the mr920? I’m sure the adjustable spring is fine, but id rather not have a chance of self adusting. thank you for taking the time to reply!

      Hi Jay,

      The adjustable aspect of the assembly is not the spring itself, it is that there is a screw that allows you to remove and change the spring installed so that you can adjust the weight of the spring used. We use a bit of blue Loctite on the screw to keep it in place, so it is unlikely to unscrew on its own. However, in the case that the screw did come off on its own, the spring would still stay in place and function normally, it would just not be retained as easily during disassembly. Hopefully this helps to relieve any concerns!
