New Thompson 1927 A1

I have learned something today, as I, obviously, thought that the M1, and M1A1 both had fixed firing pins in the breachface. I have never spent any time with either one....the 1928, well about 40 years. There are a lot of differing opinions concerning the Blish Lock system, and exactly how well it did or did not work. It makes for interesting reading.

The M1 and M1A1 Thompsons were much simpler and faster to manufacture and therefore cheaper to purchase than the 1928A1. They will only utilize the box mags, not drums, and had very simple sights over the Lyman adj. rear sights. Also the Cutts Compensator was dropped. It looks like a 1928 somewhat, but is quite different in many ways.
