Thought I would give everyone an update on the barrel fiasco. As it turns out the manual is correct. Any LT-20 that has a K at the end of the serial number takes a short 1-3/8” tang. The Same as the LW-20.
If the LT-20 has a “U” designation at the end of the serial number is has the 3.5” tang.
How the conclusion was reached is a member has a NIB never been fired that he bought new, LT-20 with “K” designation it does have the short tang barrel like the 870s.
