The Effect of Time on Rusted Firearm Identification
January 2022
Although iron-based metals are popular for making critical parts of firearms, they are susceptible to corrosion or rust. There is currently little research on how long a firearm can be left to rust before an identification is no longer possible. This project evaluates the effects of rust on the common working surfaces of Glock and Smith & Wesson Sigma firearms.
