I don’t find it complicated myself, but that’s mostly a function of experience- I mess around a lot with machines and taking guns apart doesn’t faze me much. I find mine does everything I would ask of a pistol, and if it can’t do it, its time for a rifle or shotgun.
If it ain't broke, don't fix it. ;)
That whole decock lever thing on the sig freaks me out every time I use one.
