Our Rear Slide Cover Plates offer a durable, lightweight, high-quality billet aluminum alternative which replaces the factory plastic plate. Featuring our inside pocket profile CNC machined just like the factory profile for 100% direct fit & precise tolerances. The main feature of these plates is that they are made from aircraft-grade aluminum, much stronger than the OEM plastic polymer plates. Modern gun trends favor polymer because of its light-weight properties for EDC, but our plates are the perfect replacement as aluminum offers an extremely strong material yet still retain light-weight properties. These products are offered in an array of finish options as well as with & without lasered options to provided that true personal added touch as well. Available in multiple finishes offered with & without laser engraved designs for that added personal touch.
