I have the subcompact. Highly recommend that over the compact. The compact you do get the rotating barrel but only .2" more barrel. The subcompact has a flared bull barrel and is insanely accurate! It is also smaller in size by a fair amount.
I have a large hand but with the large blackstrap and flip out finger extension. It fits me like a glove. The storms are a wider gun, but are a joy to shoot!
