The new SIG SAUER X-CHANGE Kit is the perfect accessory for your SIG SAUER Classic .22 rimfire pistols.  Now shooters can add SIG SAUER centerfire performance with just the change out of the slide assembly, barrel, recoil system, and magazine to any of the standard production pistol calibers. Exchanging components does not alter the reliability or accuracy of either assembly. Each SIG SAUER X-CHANGE Kit features SIGLITE Night Sights, one magazine*, and a hard carry case.


Owning a SIG SAUER Classic .22 and a centerfire X-CHANGE Kit provides the added benefit of owning two pistols in a single premium package. More shooting at a lower cost with the full size SIG SAUER pistol you’re accustomed to; the SIG SAUER Classic .22 caliber pistols that now include the option for centerfire performance with a SIG SAUER X-CHANGE Kit.
