Some pistols look as if they have spent their lives behind glass. This SIG Sauer P210, recently featured by B&T Switzerland, looks like it has spent considerably more time doing what pistols are meant to do. Its worn finish and well-used trigger give it character, even if we can only speculate about how many rounds have passed through it. The P210 has a serious history behind it. Developed in Switzerland after World War II, it was manufactured by Schweizerische Industrie-Gesellschaft (SIG). Adopted by the Swiss military in 1949 as the Pistole 49, it became known for its careful manufacturing, close slide-to-frame fit and excellent accuracy. The original P210 is an all-steel, single-action 9mm pistol with an eight-round magazine. Its slide runs inside the frame rails, an unusual arrangement compared with many contemporary service pistols. The result was a pistol that earned a reputation for precision. B&T's contribution is a modern update that does not require replacing the old pistol. The company offers an ACRO Cut for existing SIG P210 and P49 slides, allowing an Aimpoint ACRO P-2 enclosed red-dot sight to be mounted directly. The cut is machined into the slide to provide a particularly low sight line, bringing a modern aiming system to a design that predates pistol-mounted red dots by decades. There is one trade-off: the original rear sight is removed during the modification, but something tells me the owner doesn’t need it.Today's Photo of the Day is a reminder that even a classic can get a second chapter. And if that trigger could talk, it might have a few stories to tell.Would you modify a classic P210 for a red-dot sight, or keep it original?Image source: B&T SwitzerlandIf this post has you ready to hit the range, head over to gunranges.com - a free directory to help you find shooting ranges near you, wherever you are in the United States.
