The three story Beretta Gallery on Madison is nice place to visit. The guns are on the uppermost floor. Last time I was there they only had some new Beretta gallery guns and rack of plastic stocked Sakos and Tikkas but no second-hand classic guns. Nice place to get clothing if you can afford them. There is Holland & Holland gallery someplace near NYC Public Library, but I have never went inside to take a look. The subway system and bus system makes driving unnecessary which is very nice. The Manhattan Island where tourists frequent is very safe place. If you on a subway and want to look like a local don't look around just pick on spot on ceiling or opposite side and keep staring at that one spot.
