Your Questions Answered
Will this slide work with my aftermarket frame?
It is engineered for OEM Glock frames. We had one return where a customer experienced a tight fit on an aftermarket frame. It functions perfectly on factory frames. Fitment on non-OEM frames cannot be guaranteed.
Does the finish wear off easily?
No. The PVD (Physical Vapor Deposition) finish is exceptionally hard and resistant to holster wear, solvents, and handling. The iridescent effect is within the coating layer, not a surface treatment that can rub off.
What parts do I need to complete this slide?
You will need a barrel, recoil spring assembly, and sights. All standard Glock 19 internal parts (firing pin, extractor, etc.) transfer directly from your factory slide. An optics plate and screws are included for red dot mounting.
