I have an older Stratford 3" model (Son of Sam special) currently on layaway. It looks barely used, but does have a little bit of wobble, even in "full lockup". Not too crazy about the wobble, but I don't think it's a huge problem (I sure HOPE it's not a huge problem!).
The gun doesn't have any endshake.
My main carry piece is a current production 2.5 stainless .44 Bulldog that locks up like a bank vault. I also have 3 vintage Charters (2 Undercovers and 1 Police Bulldog .38) that lock up solid.
Hoping to hear from some of the other vintage Bulldog owners out there on if a little side to side wobble at lockup is okay. I've seen where vintage Bulldog owners will say that their guns are a little loose (sometimes from trying to "hotrod" the loads), but they still shoot okay.
