Been trying to get a Magazine extension for my Vinci.
The Stoeger Canada rep thinks it can only hold 5, 2 3/4 and I told him i wanted the 5, 3" tube listed in the manual ( M395 as listed on page 40 in the Vinci manual)
as the Canadian legal limit rides on maximum length.......dunno how it's gonna go yet.
I have a SBE II with a mag extension, and it's way better for 3 gun because it's a 3.5" gun and can hold 7, 2 3/4's in the magazine. then it can ghost/float one.
I could not get my Vinci to ghost/float one, tried everything I could, and it's only and 3" gun so 6, 2 3/4's
So, for 3 gun, just from a volume standpoint, the SBE II wins by 2 rounds.
