Development of the SIG P220, aka the Swiss P75 Army Pistol
The SIG P220, adopted by Switzerland as the P75, evolved from the expensive P49 (SIG 210) to meet military needs for a more economical service pistol. Its innovative design featured an alloy frame and a unique folded sheet metal slide, reducing production costs. Development spanned prototypes and testing, including .45 ACP variants, before its official adoption in 1975 with refinements for mass production and safety.
