So after hearing about a few revolvers that are advertised as a 4 inch barrel but are actually a fraction longer and qualify for restricted status in Canada......has anyone measured a S&W 329PD? How would one accurately measure a revolver if I end up in the US and find one to measure? I know it's long shot...but if even a 0.0005% chance is worth the time with a caliper or ruler or whatever if I see one in my travels.
