I've been married over 30 years...and never pulled any punches with her either. I'm willing to give it a try just for you....
Binko that sure iz one jam-up H&H...it makes yOu look so hot.
I wouldn't let the hinge pin screw being buggered worry you one little bit. (Probably done by an amateur like me with a screw driver giving her a gun'yO-logical exam....nothing to worry about I promise).
On the barrels being pitted...nothing to fret over....most barrel walls measure 25 to 50 thousands...ever hear the old saying "bottomless pit"....don't let it worry you none they were just kidding...all pits have a bottom.
Next time you pull out a dial caliper look at 25 thousands then try and guess how deep those pits are.
They probably got there because the last guy "drooled" down the barrels.
Don't let it worry you none...but I would keep the "drooling" down to a minimum.
Ps...Binko the gun doesn't make you look fat.
