Smith & Wesson SD40 VE Locking Block .40 S&W Used OEM Part SD40VE5
$16.99
This listing is for the Smith & Wesson SD40 VE Locking Block, .40 S&W (Used OEM Part SD40VE5) only.
Used factory original Smith & Wesson locking block for the SD40 VE semi-automatic pistol chambered in .40 S&W. The locking block is a critical frame-mounted component that locks the barrel into battery during firing, absorbing the forces of discharge and ensuring proper barrel-to-slide alignment. A cracked, worn, or damaged locking block causes failures to lock into battery, accuracy degradation, and in severe cases unsafe conditions — making this a safety-critical replacement. Removed from a factory firearm and inspected prior to sale.

Installation Note
Gunsmith Required: Locking block replacement requires slide and barrel disassembly. As a safety-critical component that directly manages barrel lockup during firing, installation and full function testing by a qualified gunsmith is strongly required before returning the firearm to service.
