Jodie Forster had one in Silence of the Lamb, that's why I like them.
Over time I have seen many, many folks clamor for 3" barrels, rave about the old 3" barreled revolvers, and simply sing the praises of 3" barrels.
I have yet to determine the attraction. Are they supposed to be better looking than a 2", 2.5", or 4" barreled guns? Do they shoot better? They certainly can't conceal better. Fill me in please - I want to know WHY I should want such a revolver.
Seriously - I want to know.
Gun length has the least effect on concealment.
