A little information on myself, I am 73 years of age and retired. I did 8 years in the USAF, then 17 years as a Law enforcement officer, in Ks, Ohio, and Fla. Got out of the LEO field and worked the next 12 years as an aide to the severe behavior unit in our local high school. I came to this forum to ask a question I have a 4506 S&W but has been struck by the factory as a model 645, I am looking for any and all information I can get so I thank you ahead of time for any information, I know there were about 100 that was mis-stamped.
