I just returned back from the gun store and I was mostly looking at the autoloaders but I thought "why not" and asked the clerk to check out a 686 and wouldn't you know the thing fit my hand pretty good. I walked away to think things over but I might actually get the revolver.. or maybe both? There was two different revolvers they had in stock at the front desk, one was a 4" 7 shot and the other was a 6" 7 shot. The shaved off weight was minor, but noticeable; am I losing anything significant with those two inches?
