RMR CUT SLIDE FOR GLOCK® 17 GEN 3 Reviews & Ratings

Our RMR Slide for Glock® 17 Gen3 pistols features distinctive, wraparound front cocking serrations that aid in manipulating the slide to check the chamber or clear a jam. (OK, we’ll admit it: the serrations just look cool, too.) It also comes with a pre-cut slot for easy, secure mounting of a Trijicon RMR or Holosun red dot sight. All RMR Slides also have standard Glock® factory front and rear sight dovetails for "iron" backup sights. To get proper co-witnessing with the RMR, you will need to also install suppressor-height iron sights. You can also get your Brownells RMR Slide for Glock® 17 Gen3 with a "window" cutout on top that enhances airflow to keep the barrel cool - ideal for hard-working action competition pistols. Plus, if you have an upgraded barrel with a contrasting finish or a unique exterior pattern (fluting, spirals, "flames," etc.) the window lets you show it off a bit! Each RMR Slide for Glock® starts life as a billet of 17-4 stainless steel that is machined to Glock® factory specifications inside, so it’ll fit factory frames and accept factory or aftermarket barrels and Gen3 internal parts. Slides are heat-treated to Rc 41-44 on the Rockwell C scale for added surface hardness and wear resistance. You can get your RMR slide in one of 3 finishes: a wear-resistant basic Black Nitride, or a thin, extremely tough, physical vapor deposition (PVD) coating in Bronze or Flat Dark Earth (FDE).

A Few Malfunctions and Finish Wear

I installed this slide and a Brownells replacement parts kit on a Gen 3 frame with a KKM barrel, and experienced 12 failures to extract and 4 light primer strikes in the first 1,000 or so rounds with Winchester NATO 124 gr ammo. The slide doesnt reliably chamber a round from the magazine when using only the slide catch, but has chambered 100% when I retract the slide to release it. Ive polished the ramp/chamber, installed an Apex extractor, and put in an OEM striker spring to see if those items resolve the problems, but havent gotten to the range with this pistol combination since. I like the ergonomics of the front cocking serrations, and the machining is very well done with no visible tool marks anywhere. I bought the bronze PVD finish because it was the only option available at the time, and its already showing wear. The muzzle area is showing holster wear, and internally the finish has worn to bare metal wherever there is metal to metal contact. So, if appearance is important to you, be aware that the finish on my sample of one isnt robust. Im confident Ill sort out the malfunctions with the right combination of parts, but i wish they hadnt happened. I would buy again.

Poor quality control

I purchased this slide and upon inspection the serrations werent sharp. The nitride looks good. Reason I gave it three stars. The hole were the extractor plunger sits with spring and spring loaded bearing is not drilled out. Based off the other photo Ive seen in these reviews before purchasing someone had improperly machined slot were the extractor sits. It seems to me they are not inspecting these slide for defects or incomplete machining. Ive contacted brownells so far heard nothing. I was able to ship the slide back through my brownells account and waiting for a refund. I guess well try again after the refund.

Will not mount an RMR

This slide will not fit an RMR with the screws that were supplied.

RMR screws not the same as with Trijicon

The holes to mount the RMR on the slide use smaller screws than what come with the Trijicon RMR. The little screws that come with the slide fit the holes but are too short to work with my RMR. I am going to have to buy screws that are the right diameter and thread pitch but longer length to mount my RMR sight.

A nice product, but...

I gave this piece three stars, if I could I would give it 3.5 stars. Here are my reasons. First, while installing a factory Glock (white in color) channel liner it was destroyed. I purchased the channel liner here at Brownell's and assume it was a factory part. It seemed rather flimsy. I used a Brownell's channel liner tool on the second one, after cleaning the hole out thoroughly with alcohol on a swab. In hindsight I should have looked closer and cleaned the hole out where the channel liner fits the first time. The second channel liner was black (also purchased through Brownell's )and I am not sure if it was a factory Glock part. It had burrs on it so I cleaned them off, and then it slid right in. The channel liner was an inconvenience, I probably should have cleaned it out the first time I tried it. The real issue is the RMR mount. The supplied screws are too short to properly retain the RMR properly. They need to be about 3mm longer to hold the RMR. Using the supplied screws only 1-2 threads are holding the RMR down, I wouldn't trust it. So now I have to source some longer screws. Apparently I am not the only one with this issue as I saw a question asked about the screw dimensions so they could also buy the correct screw. It is a 4x40 tpi T10 drive countersunk flathead .237" long. Other than the RMR screws it is a very nice slide! The fit and finish are nice, it fit well and the price was good. The coating looks very nice and durable. I wish they would include the cover for the RMR slot or at least offer one. I would definitely purchase another slide, I have already recommended this specific slide to a friend of mine. His looked identical to mine and I assume it will function just as well!
