A 30 Super Carry in a frame the size and weight of the BG2 would be a nice SD carry pistol.
I believe the 30SC will produce more recoil and the BG2 is already a snappy little handful.
The better ballistics of the 30SC, and closer to the 9mm, over the 380 ACP should be a benefit in a defense carry.
Of course, ammo availability and cost may be a challenge for the average EDC.
