I wouldn't worry about it being only 21". I betting that will flat out shoot within most peoples ability. I have 2 short GM made 54s that are great shooters.

Im not a traditional fan but at that price, i would have done the same thing and bought the GM 21" 50cal. IMO you will have an awesome like new shooter for a fraction of the cost of new.

The first DISCs were GMs with only 24" overall and less once you figure in BP length. Most people agree they were one of the best DISC based shooters Knight ever sold.
