I haven’t bought or traded much since the COVID pandemic wrecked our lives but have been lucky in the last month to buy a couple of pieces from a friend who has decided to slim down his collection. He knew that I was a fan of the Smith & Wesson N frames and my fondness for the model 28. He permitted me to have his service revolver at a very special price. Did I miss the mark at $500.00 or do I owe him some more money? S&W model 28-2 400 target trigger and hammer.
