Taken a look at a gun you own but never really use, maybe a project, maybe not, and say to yourself "Man, I should sell this thing. I never use it and I'm sure there's someone else out there who would love playing with it, and it really deserves to be out on the field. Ok, Let's do this. I'm going to get it all set up and put it up for sale."
Then you spend an hour or two airing it up and getting it shooting well for the next guy. You oil it, replace O-rings as needed, maybe switch out an ASA or a grip frame around from your secret stash of (mostly) automag parts that you hide from your girlfriend so she won't know the true depth of your psychotic troubles. Anyways, you juuuuuust get it shooting 280 with the level X tuned to stop on a rolled dollar bill, and something goes off in the back of your head that says "Wow, this thing feels and shoots awesome, maybe I should just keep it in case my brother's friend's little cousin comes out with us sometime..."
Anyways, does that ever happen to anyone else? Cause that just happened to me this afternoon
Still not sure whether I want to sell or keep, or whatever. Ah, guess that's just the nature of the struggle.
