Just got a 110 Switchback in .308 WIN. Looking at the detachable 4 round magazine, it is different than the magazines listed in Savage's store. No, the manual isn't specific as to the part #, and Savage hasn't answered email inquiry. Can anyone with this model confirm the magazine model number? And if there's a 10 round that fits, what that model number is? (I'll post a specific pic once I get to that permission level...) Thanks!
