I, like so many other 190 owners, found this forum while looking information on disassembling my rifle. For those who may have missed the earlier thread, the manual is available online here:
Also, I did the same thing that jlyent mentioned on that other thread and lightened my trigger pull by bending the spring. It feels much better, although I haven't yet taken it out to test it.
One other thing-I've seen this rifle described as being able to fire shorts as well as the longs and long rifles that are mentioned on the barrel. Has anyone tried this? How does it do?
