I dunno how many is "enough" but I have over 200 handguns. That C&R is addictive as hell and in the past there have been some good deals on CZ-82 and P-64 guns in Makarov cal, Tokarevs, as well as a few Sistema Colts and Ballester-Molinas. Besides I have some family members that could be rapidly armed if TSHTF. I also have a "few" cases of ammo socked away as well.
Don't even get me started on the long guns (over 350).
