Review: ATEi Glock Slide Milling: Building A Roland Special Part 3

So far we have added a KKM Barrel and a Raven Concealment Freya mag well to our Roland Special build, now comes the slide milling. The ONLY correct choice for a Roland Special is to send your stock slide off for some ATEi Glock slide milling. Doug has a way with these slides and has been widely accepted as one of the best, if not the best man to put a cutter on a slide.

So what do you need in order to complete the slide? A set of AmeriGlo GL429 NON-TRITIUM suppressor height sights, a Trijicon RMR RM06 adjustable LED red dot, and a Trijicon RM63 RMR sealing plate. Once you have all that gathered up, drop your stripped slide, RMR, sights and sealing plate into a box to ATEi with a work order form for the below list along with a check. The total cost of the milling was $440 on my slide, options will change the price.

  • RMR Pro Cut (They need the actual RMR that is going to be mounted for this.)
  • Half top serrations
  • Enhanced front serrations
  • Enhanced rear serrations
  • Slide refinished in Black Nitride

Sadly I don’t have any pictured of the slide in the milling process, so we will have to take a look at the finished product. I don’t know what Doug did to the slide, but it is smoother than ever before, and sort of glides on the frame rails like you would expect a $2500 1911 to feel. It is nothing short of mind blowing.

The RMR fitment is unsurprisingly impressive given all of the good I have heard about Dougified slides. The Pro RMR cut means that Doug measures the RMR that you sent in with the slide and alters the mill’s program for your RMR’s dimensions. Each one is slightly different than others, and the tight fit will help the RMR retain zero no matter how rough you are with the pistol.

While the RMR cut is the largest benefit to the slide milling, I find that I appreciate the ultra aggressive top serrations just as much as the artful RMR milling. With the new top serrations clearing malfunctions and chambering a round without putting dirty fingers on the RMR is much easier than before. You can even cycle the slide on a forearm or other object because of how aggressive the serrations are without being overly aggressive.

Just like the rest of the slide, the top serrations are beautifully machined and finished perfectly. If you had never seen a Glock before, I think that it would be easy to assume they came from the factory thanks to how well they are done.

As soon as your eye makes it past the top serrations, you come across the enhanced front serrations that Doug cuts into the perfect position. They aren’t too close to the muzzle like some forward serrations and are sharp and grippy without being too aggressive.

The correct option if you are cloning a Roland is to have Doug gut the enhanced serrations through the roll marks. The Roland Special is all business after all.

Doug also widens the rear serrations to match the front should you prefer to use those. Frankly, I feel like on a pistol without a red dot, they would be beneficial. On an RMRed gun though they are little more than well-machined decoration.

While I was out at the range, I decided to test out the top serrations to see if they were as grippy as everyone has said they are and wasn’t disappointed. Just putting some pressure on the top of the slide and moving my hand back I was able to cycle the slide without much issue.

How about shooting with the RMR equipped on my Glock? It is an outstanding experience that I think everyone should try a couple of times. Not only is it faster to transition between targets but shooting a red dot accurately at longer ranges is a snap.

So far the Roland Special is starting to come together. As you can see from the above photo, I have completed it but still intend to continue with the series.

Doug’s machine work over at ATEi is nothing short of masterful artwork. Sure, it is a bit more expensive than some of the other shops out there but do they have the track record that ATEi has? That answer you were looking for is no.

As stated previously, the retail price for the machine work and refinishing done to my slide is $440. ATEi also has a Roland Special package that allows you to send in a completely stock gen 3 or gen 4 Glock 17 or 19 in along with a $2300 check and receive a finished Roland Special back when it is done.

You can visit ATEi on their website HERE or take a look at their Roland Special package HERE.

    Have you experimented with changing the recoil spring weight now that you have the RMR installed? It seems most people continue with the 18# stock weight, but I’ve seen people run both increased and decreased rate springs. Is this something you intend to tinker with?

    • Patrick R. – Senior Writer

      Nope. Stock recoil spring is the only thing I have used. No need to change it IMO.

    What happened to part 2?

    Can we not count? I’ve been looking for part 2 for the longest, all I’ve seen is part 1.

        Thanks very much, my apologies! 🙂

        Thanks for the info, my apologies. I’ve been keeping an eye out for this series, and missed that one.

    I’m just here for the comments.

    • Monies

      It seems tradition to take the piss out of Patrick, especially on the Rowland Special posts. Just to let everyone know, I fully intend to do my part.

  • Al

    The most amazing part is that you can do all of that to a Glock, and it continues to work.

  • Monies

    $2300 plus the original G17? Hory sheet. Thats getting into ipsc open divison prices. You could get a sti or CZ Czechmate for that money. Or a Harbor freight mini mill for about $600 and do your own milling work for a red dot plus have nearly limitless gun modification/part fabrication capabilities for the future. I realize not everyone can machine, but nearly anyone mechanically inclined should be able to do the rmr cut with a little practice.

    • raz-0

      How the hell do you spend $2300 on top of the cost of the pistol to do this? At police trade in prices, that’s coming VERY close to my built by a good smith form a box of parts custom 2011 limited gun.

      • Monies

        Getting scammed perhaps? There are a lot of actually fine pistols to be had at 2.5k that will put the plastic fantastic to sleep. If I dump 2.5k in a autoloader, it is going to be a Cz75 or 2011 Type pistol. Not to mention a ported barrel and slide would not be so long as this comped G19 making it G17 length. And that most commercial loads are not making enough gas to make a comp worth while really.

        • Bart Jabroni

          Tbf the comp is only there to keep the weapon light glass clean and any recoil reduction is a secondary feature. I’m surprised the mall leprechaun hasn’t slapped that dumb ass strike slide comp on it yet.

  • Monies

    On a second thought, this is kind of like that dynamic pie/assailant arms ultimate Hi Point leading to total force construct domination with the facilitation of mounting of optical target acquisition systems.

      • iksnilol

        It’s a dynamic operative threat and assailant elimination system with built in overwatch capability.

          I like this.

      • Monies

        Incase they don’t approve my link to the video, Youtube search “dynamic pie concepts ultimate hi point” It is pretty much what we see above, except it is a hi point c9!

  • plumber576

    Next, holsters and how to carry?

  • Joel

    The RMR to slide fit looks excellent.

  • USMC03Vet

    That is a lot of money to piss away on a Glock. Then again nobody claimed Glock buyers were smart with their money in the first place. They obviously know their market.

    • Dan

      Yep and all this coming from Patrick who not to long ago told us how he needs to sell guns and needs to make money off youtube vids to buy ramen to live. Oh but lets spend $400 to shoot steep plates easier.

  • Ryan L

    or ya know you could get a sig 320 compact rx and ~10k rounds of 9mm.

    Ten thousand rounds might not look as cool on instagram but I suspect it might make you a better shooter than the roland special.

    The gun world needs doodads to drive revenue I get it but sometimes it seems a little over the top.

  • Grant

    I had ATEi mill the slide on my G19 for an RM06. With their enhanced rear serrations, a sealing plate, refinishing the slide and shipping both ways it was about $420. I bought an RM06 from Sportsman’s Guide during one of their 20% off sales for $480 and Trijicon tritium suppressor sights from B&H Photo for $124, both with free shipping. So it’s about a $1500 gun. I thought about getting a Glock MOS, but I like how solid the RMR is mounted on my gun. I haven’t tried it yet, but I have heard you can even change batteries without re zeroing because the RMR is so tight in the pocket they machine for it.

    I am very satisfied with their work. You can easily spend an insane amount of money at AETi, but if you stick to the basics I think their work is pretty reasonable. I could have saved around $100 by skipping the rear serrations (it is easier to just grab the RMR when racking the slide) but I thought they made the gun look better.

    I’m still getting used to shooting a red dot on a pistol, but it is amazing how accurate you can be at distance.

    One of my coworkers has a Glock 10mm with a tritium RMR, front, rear & top serrations and full grip stippling done by AETi. It is a beautiful gun and it is why I went with them.
