The Wilson Combat Plunger Spring Assembly in stainless is a small replacement spring assembly that sits inside the plunger tube, providing tension to the thumb safety and slide stop plungers. Wilson Combat is one of the most respected names in match-grade 1911 pistolsmithing, and this assembly is a simple, inexpensive part to keep on hand, since a weak plunger spring can cause the thumb safety or slide stop to feel loose or fail to detent properly.
