The PERFECT one is the one you like best, until you find a better one. Seriously, do you think the perfect holster for a guy that weighs 450lbs will be the same one that a gal likes that weighs 95lbs?
I like the Crossbreed Supertuck for 4:30 carry. I just ordered a Mika IWB for 3:00 carry.
For reference I am a 180lbs of rippling muscle trapped in a 230lb body.
