The indoor range that I go to was just recently sold and all the rental guns are now up for sale. They have a S&W 640 Centennial (.357) for $275. I'm familiar with this gun and have shot it myself. It appears to be in very good condition, cylinder is tight, no scratches etc., and I don't think it has been shot all that much. It has been a rental gun for quite some time but everytime I have gone to the range it has been available and the guy behind the desk told me once before that not too many people rent it. I imagine this gun is about 2 -3 years. old, I'm guessing. Is this a good deal and is it as good or better than the new 640's. I have been planning on getting a 640 anyway so would appreciate advice and opinions. Thanks much, Mike
