The Vapor slide is designed with a combat-cut sight configuration. This optimizes the slide for use with a red dot optic, providing a clearer sight picture through the back of the optic with minimal obstruction. The slide is intended to have a red dot installed as the primary sighting system, with the iron sights providing a functional backup in the event of an optic failure. Because this slide is specifically designed to be used with a dot, we do not include – or even manufacture – a dedicated cover plate for the optic mount.

Do you include a channel liner with your slides?

I have a pending charge on my account, but my order failed
The line item you’re seeing on your statement is simply a pre-authorization. Most online payment processing gateways will pre-authorize a card while checkout is being completed. Since your order was not completed or processed, the funds were never captured, and the pre-authorization should disappear from your bank statement in 2-3 business days.
Do your slides come complete with all parts?
At this time, all 9X slides are sold stripped and ready to be assembled with the sights, optic, and internal parts of your choosing. Please make sure to double-check that you’re ordering the proper generation of slide and parts, as Gen 1-4 and Gen 5 parts are not cross-compatible.
What can I expect from upgrading my Glock trigger?
Our trigger shoes do not drastically alter the feel or pull weight of the trigger system on their own. We have lightly modified the trigger pin position to shorten the pull length and provide a slightly crisper break, but we recommend experimenting with various combinations of upgraded connector, striker spring, and trigger spring if your primary goal is to optimize the performance/feel of the trigger.
Why won’t the website let me order a threaded barrel?
Most likely because you’re trying to ship it to California. California prohibits the sale of threaded barrels and expressly forbids retailers to ship threaded barrels into the state. We like staying in business and not getting sued out of existence, so don’t get mad at us. Thank your local lawmakers and fellow voters for electing them.

What are maritime spring cups?
Maritime Spring Cups were designed to accommodate a request by a special operations military group who was concerned about the ability to fire their Glock pistols after they had been submerged underwater. The ports in the Maritime Spring Cups were engineered to allow water and debris to empty out of the firing pin channel, preventing malfunctions.
While this might seem beneficial, the ability for more foreign substances to come out also means that more foreign debris can come in.
The fact is, you can still shoot a Glock underwater even without Maritime Spring Cups, though we don’t officially endorse or recommend it. Your goldfish and your toilet bowl will both appreciate your restraint.
