Wilson Combat Plunger Tube, Stainless

The Wilson Combat Plunger Tube in stainless steel (Wilson Combat part no. 458S) is a replacement frame component that houses the spring-loaded plungers pressing against the thumb safety and slide stop. Wilson Combat is one of the most respected names in match-grade 1911 pistolsmithing, and the plunger tube is staked to the frame rather than screwed on, so replacing a loose or damaged one is a job most shooters leave to a gunsmith. This version is machined from stainless steel for added corrosion resistance.

Key Specifications

• As the plunger tube, it houses the spring-loaded plungers that press against the thumb safety and slide stop.
• Machined from stainless steel, resisting corrosion better than a blued finish.
• Because it is staked to the frame, replacement is typically handled by a gunsmith rather than a simple drop-in swap.
• Plunger tubes are staked using raised dimples pressed into the frame, a factory-style fitting method rather than screws or adhesive.
• A loose or improperly staked plunger tube is a common cause of a thumb safety or slide stop that fails to detent firmly.
