well used guns are a crapshoot. most of us dont want to buy one without being able to look at it. and most people who get one dont have the option of having it sent to a good who can tellif its crap or not.
for example from their website.
they were selling police revolvers from major cities in austrilai. all sw model 66. nice looking guns. but customers were ordering guns listed as safe to shoot, and finding them with cracked forcing cones and other defects that would have cost 2-3 times the purchase price to have fixed. not exactly a good bargain.
