The short barrel stuff clocks some sissy speed as noted above, but they are low flash and not too loud and opens up to a half inch. When I feel like carrying hotter, I put my SP101 on my hip and not the airweight 38 or in addition to it. It doesn't bother me that 9mm usually well outperforms my 38, I have several I could carry and sometimes do, but that airweight is always on me. For whatever reason I just love the wheels.
I certainly understand wanting to maximize your carry cartridge of choice, especially if you only carry one gun.
I do not love the bright sword for it's sharpness, nor the arrow for it's swiftness, nor the warrior for his glory. I love only that which they defend.
