My trusty Sig Sauer M11a1 is now my rusty Sig. First I saw a splotch on a magazine. Then the back side of the controls and even the darn FIRING PIN! So now it will need a complete teardown and thorough cleaning. What I find odd is that this handgun is supposed to be non- rustable. First I will shoot the heck out of it. Neither my old P226 or P220 show any propensity toward rusting. Have any of you had a similar issue ? Thanks the Rudedog.
