I didn't find a thread on this subject but there must have been at least one. I want to know whether the 3K mags work in a 1907 (mine was produced in 2010-Ser#26043). It seems I read somewhere that the 2010 forward production had a unique magazine--is that true? The mag I have has a single cutout at the bottom and it works well.

I just got this Savage so still learning about it. Would appreciate any help.
