I saw one in the store today for $350.00,looks great. The serial number is AWA20XX and I'm looking to find the manufacture date . It would be used for the house and sometimes carry. I have heard that using 38 would be OK with 357 occasionally. How difficult would it be to go from a 4 to a 3" barrel? I always thought the 65 was a great gun and have been looking for a while. Any and all feedback appreciated.
