Well, that was fun - thank you! Are those all Ahrends stocks? Thought I saw a set or two from Eagle.
I have a 15-3 of my own - it's the most accurate handgun I've ever fired and I've been lucky to try quite a few. Maybe the 3rd time is really the charm.
I have a run of 15s, -1,-2,-3 &-4. They are very accurate. The 14-3 is SA only and is very accurate. The 17-3 is quite good as well. I guess they are all great!
