Known Issue [Solution]
A lot of people who purchased this product (and similar Brownells Glock slides) have stated they experienced consisted ejection issues. I was experiencing this issue as well, and was worried the money I spent on 4 separare Brownells slides were wasted. Luckily I found the solution... if not already done, you should change out your Gen3 ejector for a Gen4 or Gen5 ejector. Please be aware, I'm NOT saying to replace the extractor. I went through multiple extractors without any improvements. The ejector is the small piece of bent metal protruding from the trigger housing that knocks the spent casing away. Not being a moving part I did not assume that would change anything, which is why I neglected to replace it sooner. But it made a world of difference. You can usually get an OEM Glock Gen4/Gen5 ejector from some sites for $10-15 with the trigger housing, but you don't need to replace the whole housing. Look online for HowTo videos on replacing the ejector on its own. It takes about 5 minutes at most.
Perfect Fit for G19 Gen 4.
All of my original slide parts fit into this slide. I did install a new channel liner with the tool. There is a metal ridge inside the firing pin wall that may look like a channel liner. It is not. Make sure to install a channel liner.
As good as OEM
Quality is really impressive. No burr marks, tolerances are on point, finish is great, and functions as expected. Happy I decided to buy this over milling my stock slide.
It passed safety check!
This slide was my second attempt to build an upper for my G19. I initially ordered one from Midway that after 4 attempts would not allow the firing pin to fall and subsequently “lock up” with the trigger stuck in the rearward position. Sent it back and after doing some searching I discovered Brownells offered their RMR cut version with several excellent reviews. Took 15 minutes to install the build kit and functions fine. Wish I had bought from Brownells the first time, it would have saved me a major headache! It’s winter here in WY so probably get to put any rounds through it for a while. But fit and function so far is great and I foresee no problems. Thanks Brownells!
GREAT SLIDE UPGRADE GLK19G4
This MOS Slide upgrade is a great one considering iron sight focus difficulties with aged eyes. Slide worked flawlessly/smoothly without any issues.
Exceptional Value
To the point... This is an deep RMR cut slide for a G19 that doesn't break the bank. Sure, you'll also need the internal parts kit which can go for $60-$80, but they're easier to install than you realize. The deep optic cut is excellent when you want the optic to sit in-line with the iron sights and clear any holster retention system you might have. This slide is now on my duty pistol.
Simply Awesome
As soon as I had this assembled I was off to shoot it. I was concerned due to some other reviews. All I can say is it ran like a dream on everything I fed it. Thanks Brownells !!

Works. No Issues
I had the RMR mounted by a gunsmith and he swapped over the suppressor sights and innards for me as well. So far no issues with the slide. I have not fired the weapon yet with the new slide but it all seems solid enough. I would say my only real "complaint" is the price but the only option I found cheaper was sending my existing slide in to be milled. For a ready to go slide the price was within what I was willing to pay.
Good to Go, will do again
Original plan was to have a good smith that does a lot of pistol work mill my slide for an MRDS (Holosun/RMR). Then I thought about forward serrations... the costs stacked up quick with more milling, refinishing, etc... About the time I was ready to drop it off I found this slide and oh man... I went back and forth for some time as to which way to go. I could not be happier with the Brownells slide, the window is a bonus! It is as tight or a hair tighter (better!) than my Glock slide. I have about 300 rounds through it in drills and a lot more in dry fire drills. Flawless, looking forward to shooting a match with it! And as my eyes go, I see more Brownells slides coming!! Get one - or two! And go ahead and get the parts kits!! The Gen 3 parts all work (recoil spring is Gen specific though). I prefer OEM parts myself.
