The L2D Combat Tyton slide is a direct replacement for OEM Glock pistols that will increase accuracy and performance of your firearm. L2D Combat slides are precisely machined to tight tolerance requirements in all critical areas of function and manufactured using premium quality 17-4PH stainless steel. Strict proprietary quality control processes combined with superior engineering and high quality materials allow for a consistent, accurate and unmatched product. An RMR red dot sight cut is incorporated into our design and features front indexing lugs for added shear strength and to maintain perfect sight alignment during removal / re-installation. Each slide includes a cover plate that can be installed in place of the RMR when a sight is not mounted. L2D Combat slides are fully compatible with OEM Glock internals, however for maximum performance and accuracy gains, we recommended using L2D internal parts kits and barrels to complement our precision machined slides.
