I'm confused so really can use some help! I've been told the 103B did not have the H&H self opening system early in it's production. If so, what made the 103B different than the 103A? Everything I've tried to read said that the H&H system was the difference.

Where the 103B's always a self opener, just not the H&H system? Or did it begin as a non self opening system gun?

Any FAST help appreciated! Thanks.
