10-day Red Dot Optic Cut Only

Got a HOLOSUN 507c ACSS installed on my Glock 19x and some Ameriglo suppressor sights, when I received my return order I opened the box and it was like Christmas morning lol. Beautiful work, super clean install, and to top it off fast service with fast delivery. If your thinking of getting the cut please don't hesitate. Thank me later

Sent in my Glock 19x slide to get cut after I called several gun smith here in Colorado, all of them said would take anywhere for 4 to 6 weeks to cut. Extremely happy my decision in sending it in to the Glock store, got my Glock back in less than a week and was extremely satisfied with the work that was done on my slide. Would highly recommend to anyone looking to get their slide cut these guys work magic.

got back wife's G26 Gen 3 with slide cut co-witness which looks great, we provided HolosunSCS and GS mounted optic beautifully. very happy

Looked at this option for my G27 gen4 for quite sometime before "pulling the trigger" and doing it. Pleased with the results. GS completed their promise in 8 business days. FedEx return shipping with signature required was a bit problematic but not GS' fault...more of a timing and schedule thing on my end. Mounted my Vortex Venom easily and it looks and fits great! Got the "no co-witness" cut and the rear sight was returned packaged and labeled with the slide. Ordered a Black Yikes connector at the time of my order and it came with the slide also. Installed it in about 5 minutes. Now to the range to zero and enjoy.

I got the co-witness cut done on my G17 slide. I went with the AimPoint ACRO cut and the work was done within the 10 days advertised. Remember, holidays and weekends aren’t part of the 10 day turn around.

This was my first slide cut ever and with GS. The cut on the slide looked good and my ACRO clamped in perfectly. I am satisfied with the work and I would send in another slide if I had the desire to add more red dots to my pistols.

I have noticed some negative reviews, but as far as my experience goes, all went well and I had no issues. The only issue I had with GS was a long time ago and my order was taking a while due to inventory (not GS’ fault).

Have no worries, send in your slide and enjoy it when you get it back.

Thanks GS.

G19 optic cut, blueing, Holosun installed plus suppressor sights in record time. Perfect!

I love my Holosun 507 HE. I had it sent to GlockStore to be cut and the Holosun 507c installed. It took about 20 rounds to get it sighted at 10 yds. Can knock the target area out. This is on a Gen 3 G19. I then shot my G26 with iron sights. Now I’m saving my money to send in the G26 and have it cut and add the same optic. I love the green optic. Best thing has happened to a 76 yr old and blind in the dominate eye.

I just received my G19 Gen2 slide with a co-witness cut. It arrived within ten working days. The cut and fit to my Votatu PMD505 RDO was perfect! (Holosun 507K footprint.) After installing the AMERIGLO Optic Compatible XL sights and a minimal amount of adjusting / bore sighting I had a proper 1/3 co-witness with the RDO reticle setting proudly on top of the front sight. I couldn't have asked for better service, value or workmanship. Great Job!

I received my finished slide (G22 Gen4) back approx. 1 week from date I shipped it out. The optic (Holosun 507C) fit was absolutely perfect. No slop. Perfectly centered on slide. When zeroing in, I was able to leave the optic's factory zero for windage, and only had to adjust a bit for elevation. I am very satisfied with how this turned out. Did have one little issue regarding delivery complications, but the Customer Service Team was very attentive and helpful through multiple communications. Big "thumbs up" to the GS machinists/gunsmiths & the Customer Service Dept. Thanks everyone!

Excellent and timely work, I live 2 hours away, drove down and dropped it off, got the call to come pick it 8 days later. They communicated with me through the whole process, highly recommend their work

Needed to mount a red dot on my Glock 19X. Overall super happy with the slide cut results the Trijjicon SRO dropped in place perfectly. Will use Glock store again for my slide cut needs. Thanks again!!!

Great service with an awesome turn around time. Spent a bit of time looking into ways to get my G25 milled for an EPS with the majority of services going for anywhere between 4 and 8 weeks turn. When I saw the 10 day offer from GS, I thought I would take the chance. And am I glad I did!!! They turned my slide a day ahead of schedule and the milling/bluing job was awesome. The EPS fits like a charm and the gun has continued to run flawlessly. Have not had any experience with GS prior to this, but you can bet going forward I will.

I sent my 19X to Glockstore to get milled and I had it back 2 weeks from the day I sent it to them. Everything looked good, optic fit well. I used some Loctite 243 and some 5/16 Holosun screws I got from another company and ran 13 x 19 round mags through it and it is still good to go. Going to put 500 rounds through it soon and if there are any issues I will update the post. Overall, I am pleased with the slide. No complaints.

I ordered a Gen 5 G17 slide along with the optic cut for a Trijicon SRO. I requested to have them test fit an optic in house, because I didn't feel like sending one in for a "custom fit." I was worried at first, but when I received it, I was very impressed.
The fit was perfect. No fight to get it in, and absolutely no play once in. The optic was zeroed for another glock with a C&H mounting plate, and when I put it on the milled slide, it was shooting dead on with no adjustment. I paired the SRO with AmeriGlo GL331 (the XL, rather than 3XL size) iron sights, and have a perfect lower 1/3 co-witness through the glass. This is much better than mounting plates if you are sure about your optic choice.

Yep. I sent them my stripped Gen 4 19 slide with my new optic in the box. What did I receive back? I received a slide with the optic that looked like it grew there. If the review would allow pictures, I would attach them. You would be impressed as I was. All this while purchasing during a sale. It did take the whole 10 business days start to finish. The only communications email you get are when it's received and when it's finished. So don't panic! No need to call unless you want to add to the order as the phone lines are very busy. If you do call, hang in there they will get to you and answer your questions. I would purchase this service again in the future.

Weapon: Glock 21 Gen 4 with original parts mounting a Vortex Venom optic co-witnessed to suppressor height sights.

After reading all the reviews and lack of negative feedback I thought they removed any critical feedback. The described timeline is accurate. The unpredictable parts are how long it takes traveling through FedEx to my residence. The Glockstore kept me well informed about each step of the process.

Once received, it was in great condition and there was no additional scratches, machining marks, or machine bits. The optic was zeroed and perfectly aligned with my suppressor sights. The machined area was cleanly cut and nicely finished. While I have not used it since it returned in the mail that part is on me not to ruin this set up. I am completely satisfied with the work, the timeline and look. I would highly recommend this for anyone interested in having a stock Glock slide milled.

Got the Combat Cut on my Glock 23. All I can say is "WOW!" Ordered this during a sale event, so I know they got slammed, but it got back in time. It looks great! Installed my suppressor height sights and red dot. Now, I'm ready to hit the range and get this baby sighted.
Thanks Lenny and crew. Now, I've gotta decide which one is next....

Great job. The slide came out fantastic! Quick turnaround
Thanks !!

The milling was very nicely done. The secondary bluing looks fine. I mounted my Holosun 507C and it fit perfectly. To top it off, it was about 8 days from the time they accepted it until I signed for it with FedEx.

I mailed my slide out on 7/2/26 and got it back on 7/16/26 exactly 2 weeks. Phenomenal job was done. The cut was great with no expected tool marks like you see when others cut slides. The optic fit perfectly when I mounted it. The only issue I had was that the screws that came with the optic were either too short or too long, so me being impatient, i decided to file down one that was too long. It took a little while, but I got it to fit perfect with no interference into the extractor plunger channel. This was in no way GS fault, but the optic companies oversight. Hats off to GS for a great job. Looking forward to sending more work their way soon. "R" cut in the future on my wife's 43X.
