I will always check the used market before buying new. If I cannot find what I am looking for or cannot make a deal in my favour I will buy new. Sometimes I have no choice on exclusive items, and I get impatient for waiting around for something to come up. When some models are a new release to the Canadian market there is no choice but to buy new as well. It is funny how the market changes over time.
New: Sig P229, S&W M627, S&W M57, S&W M629, Browning Buckmark URX, Ruger GP100
Used: Sig P220, Sig 1911 Scorpion Carry, CZ75B, S&W M27, S&W M686, Browning 1911-22A1, Browning Buckmark, S&W 1911SC, Browning Hi Power Silver Chrome
I had so much fear over buying used but then I realised those fears were unfounded. I would not have my Hi Power Silver Chrome, M27 or my vintage M686 unless I went the used route. You have to realize that many great guns will never be yours without 2-3 owners prior to you.
