Long-lasting, high quality alloy spring steel magazine spring from Lakeline LLC combined with one of our aluminum followers to fit the Sig Sauer P365.
New magazine springs, and followers, can restore your magazine's performance to like new, or even better, at a fraction of the cost of a new magazine. These help to keep your pistol performing like new.
These springs are long-lasting, high quality alloy spring steel. If you want valve springs for your car, there is another option out there. If you want magazine springs for your pistol, these are the best you can buy. The material we use takes more deflection before deforming and has a higher resistance to fatigue than valve spring alloys. And, since it is precisely cold formed and doesn't have a rough surface like their springs, shot peening would only make the surface finish worse for longevity. These are optimal magazine springs without the bull.
