Smith & Wesson Sight Blade Kit, Rear, .146'', For S&W K,L,N Frame Blue

The Smith & Wesson Sight Blade Kit is a replacement rear sight blade for S&W K, L, and N frame revolvers. Whether you're restoring a vintage wheelgun, fixing a damaged sight, or upgrading your revolver's setup, this genuine factory blade is engineered for the exact tolerances and fit that only a manufacturer part can deliver. At .146'' height, it's sized to work with these specific frame sizes—a straightforward swap for shooters who know their platform and want OEM reliability.

Revolver sights see real wear. Rough handling, fall impacts, or years on the range can bend, chip, or misalign a rear blade. Rather than risk a loose fit or poor zero with an aftermarket substitute, this Smith & Wesson original gives you the confidence that it will lock in securely and print true. If you're a serious revolver shooter—hunting, target work, or defensive carry—sight health matters.

This kit comes finished in blue to match most classic and modern S&W revolvers in the K, L, and N frame lineup. Installation is straightforward for anyone with basic gunsmithing knowledge or a trip to a qualified gunsmith. Keep a spare on hand, or install it now if your current sight is worn.
