It may be gorgeous

Which brings me to my second line of thought. Get a much shorter, ultra concealable, barrel for pocket carry as a BUG. If I did that, I may also end up getting the standard length rubber grips. As much to preserve my wood grips as anything. But, they would let me get a better grip of a larger caliber if I am thinking pocket carry.
So...
Any owners out there that can tell me your favorite barrel lengths and calibers? Both for fun at the range and for pocket carry?
Thanks
