The SIG 210, aka the P49, was a magnificent pistol, but really too expensive for a modern military sidearm. In the 1960s, the Swiss military began looking for a new service sidearm that would be a bit less costly, and SIG developed the 220 in response, which would ultimately be adopted as the P75. The P75 would maintain the basic structure of the P49, but used a folded sheet metal slide design and an alloy frame, significant departures from the all-milled construction of the P49. In today's video, was have a fantastic set of P75 pistols to look at and see the whole developmental process. This includes two iterations of the first prototypes of the design, one of the very first production Army P75s, a standard late production P75 showing the final simplified features, and a Z-series border patrol example with its unique magazine release shield.
