I have been looking at a Ruger Blackhawk convertible, the 5 1/2" 38/357 with the extra 9mm cylinder. My reason for interest in this model is that it is the only 5 1/2" version currently available. I do not need or want the 9mm cylinder. My concern is this:
38 special and 357 magnum bullet diameters are .357 for jacketed and .358 for lead. Nine mm bullets measure .355 and .356 by comparison. So I wonder about the groove diameter of the barrel. It cannot shoot both 38/357 and 9mm well. It is either too big for 9mm or too small for 38/357 (I suspect the former is the case). Any insights that you could provide would be welcomed.
