I have an M44 and I couldn't guess how many 100s or 1000s of rounds I have shot with it and it is still as tight as the day I bought it. All of my Taurus pistols and revolvers have been trouble free. I shoot competition with a Taurus PT92 that has nothing more than a little trigger work and different sights. I have Kimbers, Berettas, S&W, Rock Arms stuff too. Granted, the high end hand guns look nicer, but the Taurus hand guns always fire for me. Without the extras, that M44 is worth $400.00 retail and if I was buying it, I would offer $350.00. Used is used regardless of how many times it has been fired. Used gun values never take into account how many times it has been fired unless it is unfired/new in the box.
Like others have said, firearms have a wide range of opinions on what is good, and what is junk. Kinda like the Porsche guys at the road race track. Everything other than a Porsche GT3 is a waste of time accorrding to them, but a new Corvette will run the same lap times and cost 1/3 the money.
