New Thompson 1927 A1

Postino,

Yes, the closed bolt firing is one of the characteristics of the semi-auto. But I guess I need an extramural seminar at Luger U. because I'm not familiar with the mechanical characteristics of the open bolt that make it what it is. I'll Google around, try Wiki, etc. and try to understand it.

Interestingly, I did not sense what you were saying about the point of aim. If you're referring to the possibility of the bolt's momentum taking it off target--behaving like a Luger which is limp-wristed?--, I think the massive mass (heh) of the rifle minimizes that; plus it has a compensator. I think I'm not talking agout the same thing you mean, as what I describe is about the bolt on the way back, not forward. If that's it, then it might be that a proper ratio is maintained when comparing the weight of the entire gun to the weight of its bolt. I got it on the paper with most of the test shots, but I'm still trying to get comfortable with the sighting system. Reading glasses help with the front blade, but the rear notch is virtually invisible to me. the ring of the peep sight, when raised, is likewise a fuzzy halo for me. Would the military style of rear sight help me any? Maybe a scope...
