I own a Colt Government Model, MKIV, Series 70 manufactured in 1981, bought new by me in 1983. I have never had a problem out of that weapon in 24 years. Granted, it hasn't been carried everyday, but it's shot enough to leave me comfortable with carrying it, should I desire to. I bought it new for $200 and currently the value, as a shooter is $650 (no box, no paperwork). Pretty good investment if you ask me.
Are they priced excessively? Not in my book, not even in today's market.
