I never used to have rhyme or reason and picked up what caught my fancy then. Now I've traded some of those same guns off and mainly look for S&W revolvers and 1911s. Since I retired my spendable income has dropped and I've mainly been trading guns now.
My last two were a Ruger 1911 Commander size and Sig 1911-22.
I also brought out my Kimber Ultra CDP I hadn't shot in years so almost like getting a new gun.
I'll probably stay on the 1911 kick for awhile as S&Ws are hard to find here. My dealer had a no lock Scandium J frame in 22 LR that I had some interest in but no good reason for buying so passed on it.
I have some S&Ws I'm still looking for but chances of finding them are slim but it's about the hunt really anyway.
