SIG M2

I saw a SIG M2 in 45ACP. has a rotating barrel lockup and polymer grips. it is striker fired and has a weird side to side toggle safty on the back of the pistol. Is a eight shooter; and heavy unloaded. Feels good in my shooting hand though. question: any one have the word on these? You think this is just one of those ideas-passin-through guns or will SIG/Mauser keep makin em? Price is $480-one mag here.[This message has been edited by Khegglie (edited 12-20-2001).]
