I recently picked up the Ruger RXM and fully intended to do a heavily modified build which is made especially easy considering that the RXM is based off of a Gen 3 Glock. So much so that the entire upper assembly can be directly taken from a Glock without any changes.
Case in point, my brand new upper assembly all from Norsso out of Las Vegas. This particular one is the N19 Piranha Ported Slide for Glock 19 Gen 3 and 4 with RMR cut and in Black DLC. I’ve personally built a decent amount of Glocks and Glock clones over the years, and I’ve looked at a lot of aftermarket slides from various companies, and I’m going to say without a doubt that the Piranha slides from Norsso are my favorite purely from an aesthetics standpoint. I love the way this thing looks. It’s super aggressive with all the design choices from the serrations to the cutouts in the nose. Front to back, this slide is gorgeous in my opinion.
If you look back at my YouTube channel, I actually made a build in the past with another Piranha slide, but the non-ported version. But even back then, I wanted this ported version with the top cutout but didn’t go with it back then because I didn’t necessarily want a port on top for no reason. But since that video, Norsso has come out with multiple ported barrels and one that would be able to utilize this slide cut is this E port barrel. This particular one is the N19 Gen 3-5 9mm E Port Barrel in the copper TiCN Titanium Carbo-Nitride coating. Again, just a beautiful color. I’m a sucker for stuff in the realm of a copper or bronze colorway so this was a no brainer for me. When we put this barrel into the slide, you can see that it’s a perfect pairing. The barrel and ports both seat and align properly.
Moving to the smaller parts, I have some blacked-out Angry Bear Arms suppressor height sights that are meant to be lower third cowitness height when paired with something like a Trijicon RMR or SRO. These sights are an add on option on the Norsso website and they do have others if you don’t like these, but the blacked out sights were recommended because if you go with the ported setup, all the expelled carbon will just cover the front sights and black them out anyway so no point in spending extra on the other options that feature night sights with different colors.
Internally, I’m running stock Glock parts, which are recommended by Norsso as that’s what their slides are designed around.
Again, this entire upper assembly, including the sights and internals, all came from and were installed by Norsso. The only thing that I didn’t get from them to complete this upper is the recoil spring and that’s because I’m running the KynSHOT hydraulic guide rod. This thing makes a lot of bold claims, like reducing recoil by 70%. I’ve run this spring before, and I wouldn’t necessarily say that I believe that, but one claim that has worked for me is the claim that with this spring, you don’t have to do any tuning when it comes to changing out springs. If you didn’t know, when you run a suppressor, compensator, or ported barrel, you may have some reliability issues or failures that may revolve around the strength of your recoil assembly, which you may have to adjust. With the KynSHOT being a hydraulic system, it supposedly self-adjusts and so far, I can only say that I haven’t had issues with this spring on other setups that have some sort of change in barrel pressure.
Lastly, this slide is cut with the RMR footprint. I have a few optics sitting around that I can use with this, including a Trijicon SRO, Holosun 509T, and an Osight XR. I’m leaning towards the SRO or XR, but this might be a build that I try a few different options out before settling on one.
Overall, I’m impressed with this upper assembly. I took it to the range and had no failures within the first couple of hundred rounds. It does surprisingly well at reducing recoil and this is definitely one of the nicest feeling compact-sized guns I own. I’m excited to keep building off of this gun with some more mods so subscribe to my YouTube channel for future updates!
