One of the hottest trends in the shooting world are using Red Dot Optics. Shooters have quickly adopted this combination as one of the best ways to shoot faster and more accurately.

Now this is great if your Glock is the MOS version… but what if it’s not?

Well then, you’re in luck! You can have your slide precision cut at GS Performance for the exact RDO you want. This results in a lower, more secure, and more accurate mounting method than the universal mounting plate required by the MOS versions.

Here’s what we do:

1.) We precision cut and mill your slide, then protect the bare metal with a Cold Blue coating.

2.) We then mount your choice of available RDO optics.

3.) We ship the finished slide back to you… and do it all in 10 days or less.

For complete details on the 10 Day Guarantee, please refer to the below Additional Information.

Please Note the Following:

• If you have a factory MOS slide, some cuts may not be compatible. Please call to verify.

• The SCS cut requires suppressor sights to co-witness.

• Combat Cut adds $25 to the cost due to additional handling requirements.

• Extra long slides such as the 17L may have limited optic compatibility, please call in to verify.

For additional “whole slide” refinishing options, Click Here. Also note that additional refinishing options will add at least 15 days to the “Cuts Only” Ten Day Guarantee turn around time.

Here’s how it works:

Just purchase the RDO/RDO Cut Combo. Mail your slide, stripped or not, with the sales order number, to:

GS Performance

Custom Shop / Slide Cuts

1930 Air Lane Drive

Nashville, TN 37210

Once we get it, and open the package, the days start ticking and we’ll have it cut, mounted, tested, and on it’s way back to you in 10 days… or less.


• Return shipping time is NOT included in the 10 Day guarantee.

• If you have aftermarket rear sights on your Glock, they may need to be removed before cutting. Any removed sights will be returned to you when we ship your slide.

• Once the slide is cut, you cannot return the RDO. We only offer exchanges, and only for defective units.

• Due to tight turnarounds and tracking methods, Optic Cuts cancelled after we receive the slide are subject to up to a 10% Schedule & Handling fee. Once machining has started, Optic Cuts are Non-Refundable.

10 Day Guarantee

“10 Day Period” starts when we have received and opened your package in our Nashville location and pertains to the Cold Blue finish only.

Days are defined as GlockStore Business days, Monday thru Friday.

We will cut your slide, install the Red Dot Optic, and ship from our facility in 10 Days or Less or the Slide Cut is Free.*

NOTE: Return shipping time is NOT included in the 10 Day guarantee.

Purchased Red Dot Optic must in-stock to qualify for the “10 Day Guarantee.”

Red Dot Optics supplied by the customer must be in “ready to install” condition, with all necessary hardware, to qualify for the “10 Day Guarantee.”

Sales Order number MUST accompany the slide to qualify for the “10 Day Guarantee.”

*RDO Slide Cut is valued at $150.

Best modification for a 19 G3.


Best modification for a 19 G3. This service and the accompanying products are outstanding. The 19 went from a good gun to a great gun in 10 days or less. This particular mod was for the cut with the Vortex Defender (highly recommended btw) with cowitness and Trijicon suppressor sights. The quality, craftsmanship, and service was unbelievable. If you have a Glock and want a red dot, send that slide to Lenny and team. What a spectacular service and resulting firearm! Worth every penny.

19x Cut


Wow! Struggling to find something negative to say.... They have great customer service who answered every question I had. Fast turn around time. Received my slide almost a week earlier than expected. The finish on the slide perfectly colored matched my 19x slide. The holosun 507c fit perfectly with no extra movement. The slide was returned way cleaner than I sent it. Was able to zero in at 10 yards with under 10 rounds. Sending my 43x slide off next paycheck to have it cut and have a holosun mounted on it. Extremely happy with my purchase.
