    This is my second Rock slide. Very nice construction and fitment. Can’t beat it for the price. And the FDE matched the P80 frame perfectly.

    Put 100 rounds through it with no major issues to break it in, looking forward to trying out the 31 that’s also a Rock Slide build.

    Ordered 2 G23 slides, one built in 9mm (800+ rounds) the other in 357SIG (120 rounds) . Have had NO issues so far. The finish is great. Gives a great custom look without breaking the bank. Also like that they are USA.

    Everything went together well and fired like a champ. Might have to make a couple more. The vented slide is just for looks, but for plinking at the range, that is all good. Several hundred rounds in and I really like it.

    Second G23 slide I have purchased from Rock Slide. I installed all internal parts except the sights and tried it out. So far so good! Flawless function, fit and finish. Tungsten finish looks great! My RMR went on perfectly. Currently using this slide in .357 Sig configuration with my G23 OEM lower. Very Nice indeed. Swap the barrel to .9mm and no difference in performance, except the blast.

    Great slide put it on a p80 frame and ran great right from the start. Great price and more sight cut options than most.

    I bought this upper to go with a polymer80 I milled myself and I could not be happier with the finished product. I had some initial hesitation about the tightness of the slide and considered returning it but after I followed Rock Slide’s instructions and put between 200-300 rounds through it the tightness was gone and I was shooting the smallest groups of my life.

    The quality of this upper has really impressed me. I will be buying a Rock Slide 9mm barrel soon and I will absolutely buy another upper from them for my next build.

    Super product and really really fast service. I have built 6 Glock kits from their polymer 80 lowers and the slides fit and function perfectly and are the best deal I have found on Glock slides. A big plus is if you order the slide parts kit, recoil spring and Barrel they will assemble it for you prior to shipment so when you receive it all you have to do is just install it on your lower and you are ready to go .

    I received my slide exactly 48 hours after ordering it so from computer to Doorstep was maybe 2 days but I also had them do same day delivery but that is still awsome timing!! The packaging was very nice the slide was very protected wrapped in foam & in a box with all the paperwork included!! But the actual slide itself the quality is amazing/superb you can’t beat it I believe I paid around 240 to 250 with the same day shipping and I got the G23 stripped RS2 vented slide with a Vortex Venom optic cut!!! (On vortex venom cut slide they don’t have a plate for it yet the Rmr has a plate thou) The current setup I have on it now is not a Vortex Venom but it has the same footprint as the vortex Venom!!! Ohh man let me tell you guys the fitment on the optic is amazing it fits/seats in there tighter than a 40 year old virgin nun doing kegel exercises 😂😂!!! The slide cerakote on it is fantastic I’ve been using it for about a month or two and I’m very vigorous in my draw training and so far I haven’t had no holster wear on the side of the actual slide itself and I carry kydex and my retention is very tight!!! For the money that you are paying it is well worth it and I love support supporting veterans this company is owned by veterans and made by veterans so that’s a plus!!! So if I was you that is thinking about investing in a slide or Poly80 I would do it this company is 100 legit and have my business from her out.. thanks rockslide keep it up!!

    Well made, quality machining with no machine marks, quality Cerakote finish. This slide fits my Polymer80 frame like a glove, no issues from too much Cerakote.

    I was really impressed with the look and feel of this slide.

    I couldn’t ask for a better slide. It is as good if not better than slides that are much more expensive. I will definitely buy from them again.

    Perfect fit, reliable operation, and very reasonable price. When I needed one for a PF45 project, I came back for these reasons.
