Two different companies for many years now. Sig Sauer Germany and Sig Sauer USA are both owned by the same holding company, but have operated separately for many years. Sig USA is much bigger, and is, in my opinion, the most innovative firearms company out there these days. Between the P320/M17 platform, the SIG Virtus/AR15 platforms and the biggest small gun introduction in the last decade, the P365 they are riding pretty high in the firearms world right now.
Their training courses at the Sig Sauer Academy in New Hampshire are among the best offered by any gun manufacturer, both in the breadth of the offerings and the quality of the courses (and yes, I have taken a few…)
Unfortunately their airgun exploits leave a bit to be desired. They seem to throw a lot of stuff at the wall and if it sticks, then they keep it moving forward. If it doesn’t blow up into something big, they drop it and move on. They do seem to have stuck with the basic CO2 pistols which are clones of their P226 and P320 platforms. I did buy one (P226) a couple of years ago when I was up there for a 3 day course and didn’t have my firearm with me (They will lend you whatever you need for the course however you leave it at the facility in the evenings. You only have to pay extra for the ammo). It did allow me to practice dry fire in my Hotel room everything night for a couple of hours, since the trigger was quite similar to the firearm.
