Two cz52s
Two FEG,
Two Sig Mosquitoes,
Two .22 revolvers,
Two SKS
because I usually am the one that has to supply the guns when I take family to the range and for the oddball stuff having two makes it easier to figure out where the @#@! part goes if you have another to look at as well as having a ready supply of parts or backup gun when things break.
My girls all have more than one pair of black shoes.... why even think of justification... it is what it is...
Once I figure out the gun(s) I like it is nice to have more than one
"wahl"
lol
I have 17 different Mosin-Nagants...and about half as many SKS rifles/carbines. Four M1911s, and several other firearms that I have more than one variation of.
I don't need justification, just desire...and the cash!
