This is a custom backplate for your Glock. This fits all standard Glocks gen 1-5 EXCEPT the 42, 43, 43x, and 48. It is precisely CNC machined out a block of 6al-4v high-grade titanium. Being CNC machined this ensures that every part is exactly the same and fits in your slide correctly. We offer these titanium back plates because they are ultra-light like aluminum but also very hard like steel, so you get the highest performance and durability. This backplate is DEEP engraved using our industry-leading 50-watt fiber laser to give you a long-lasting and contrasting effect. This plate is prepped and then Electro anodized for a beautiful look. This product will ship within 3 business days after ordering, but we try to ship out parts the same day as ordered. You will receive a tracking number once the shipping label is created and then shipped using USPS first class.
