I have a Ruger Mark II gov modle with the slab barrel. I love this pistol and it has been a source of much satisfaction.
A barrel was given to me recently...it is a AMT (Arcadia Machine & Tool) Stainless Steel, 8 inch barrel with grooves for scope rings. The barrel fits my frame very very loose. The AMT barrel is possibly old but I do not know how old (S# G0003xx).
Does anybody have a AMT Barrel? or dealings with this company? I do not even know if this barrel is a "Good" quality product or not? I guess I am tring to decide if this is worth the effort to correct?
