I buy a pistol every year or two and if I love one I get three with 10-mags each for home defense; My boys and I each get the same gun with extra mags just for the purpose of collective defense. We have two differnt pistols in 3’s. The Glock 17 Gen 5’s are coolest when we put the carbine kit on it. You add the 27 rounds per mag (2 ea) plus whatever else you have, it is essentially a paratrooper rifle.
I like that, that’s a great family tradition.
