That price sounds on the upper end of what one would sell for around here. Last time I looked M44 were priced at $275 to $295 in the local shop. the price stated sounds like a gun show price, though if were one I wanted. I would buy it, and not sweat the 50 bucks. Wait till later that will be a low ball price.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
