Time will tell!
Without a doubt, by a large margin. The 16" .40 is already faster than 10mm in a 5.2". Both loaded to moderate (factory) levels. So far, the comparisons have been basic and unscientific. We'll start gathering some real data, once he gets about 1000 rounds through. It should be about as broken in as it can be, by then. Any minute, now....
