Welcome to the forum, the answer to the question of "Would the 64 be a good buy for home defense?" is a resounding YES!

I bought a DAO Mod 64, a police trade in, and it's my truck/ATV/ carry and nightstand gun.

As a matter of fact, I bought two more Mod 64's after this one. A tapered barreled one and a snub-nosed revolver.

There's posts on the Mod 64 revolver on the forum. Use the "search" feature to find them.
