FAQ

Is this a complete firearm?
No. This is a pistol slide assembly, which is a key component but is not a firearm itself. It must be paired with a compatible serialized lower receiver (frame) to build a complete pistol.

Will this work on my Gen 4 or Gen 5 Glock 19?
This CA19 Pistol slide is specifically machined for Gen 3 compatibility. While it may physically fit some later generations, optimal function and reliability are guaranteed only with Gen 3 spec frames and parts.
