Great post and report. I like the gun. I have never heard of that version. Did you shoot it any with the open sights? I am more interested in a gun like this for open sight shooting. When shooting for groups did you just aim at the paper and fire one shot and use the bullet hole for the rest of the group? I have done that many times instead of using a target dot. But a target dot lets you see if you are drifting or pulling when shooting and seems to keep you more focused on a particular aiming spot.
