Picked up a Trooper MK III at a gunshow last weekend very little holster wear around the muzzle and cylinder. Took it to the range Sunday and it shot nice tight groups with 125 GR Gold Dots. This is my first Colt and I wasn't really looking for one when I went but I'm very glad I found it!!! Can anyone tell me what years these were produced?? My serial number starts 18. I paid $300.00 for it and from what I hear I got a great deal the guy had a SS one for the same price but I missed out on it.
