Smith & Wesson M&P Compact Frame Key Plug | OEM New Part 279390000
Smith & Wesson M&P Compact Frame Key Plug — Factory New OEM Part #279390000
This listing is for one (1) factory new Smith & Wesson OEM frame key plug, Part #279390000, for M&P Compact pistols.
The frame key plug is a small but essential component that fills the frame key slot when a manual thumb safety is not installed. Without this plug, the frame slot is left open, which can allow debris to enter the action. This is a genuine Smith & Wesson factory part in new condition — an ideal direct replacement for a lost or damaged original.
