45-70 introduced me to my 357 Handi and I am eternally grateful. The little carbine is a joy to hold, carry, and shoot. Tim has his Handi's "tricked out" with various lazers, scopes, and lights. Way Kool!
Now I have a barrel attachment, a Universal Weaver Base Barrel Mount, for the inclusion of various accoutrements, as desired. What, if any, change in shooting accuracy is attributable to a barrel attachment?
My Handi is a shooter now, without attachments. Can I expect the same result? Will the point of impact change? Will I need to move the attachment in or out on the barrel to find that "Sweet Spot" again?
