Less effective as a carry gun, due to not being able to be carried with one chambered
I'm curious as to why you think this is the case. The P232 has a decocker, the purpose of which is to carry a chambered round safely.
IMHO, sometimes a piece in one's collection doesn't have to make sense.
Sometimes we pamper ourselves with nice things. Sometimes we give in to wants and subjugate needs. Sometimes we become obsessed.
