How often do you prefer the lesser gun?
I've got a bunch of .22s: Lithgow, Anschutz, CZ, Henry, Wifama—you name it. For some reason, I can't give up my piece of crap Romanian 1969. I just take it to the range more often.
Similarly, I shoot my LMT MWS, LRB M14, and even HK 91 more than my decked-out SAN 751. I'm not trying to keep the SAN "nice". It's a gun, meant to be shot, and if it breaks, I can fix it or buy more guns.
When you reflect on your own behavior, do you find yourselves doing anything similarly "irrational"? In my case, it might be familiarity. I've shot the 1969 the most, therefore I like shooting the 1969 the most.
