Smith & Wesson M&P 45 2.0 Slide Stop Assembly – Used

Part Number: MP4505D  |  Condition: Used (Factory Original)  |  Caliber: .45 ACP

Restore your M&P 45 2.0 to factory-correct function with this genuine Smith & Wesson slide stop assembly. The slide stop locks the slide open after the last round is fired and allows the slide to be released when a fresh magazine is inserted — a worn or damaged slide stop can cause failure to lock back or difficulty releasing the slide. The M&P 2.0 features updated internal geometry — use only 2.0-specific parts for proper fit.
