I know this is a handgun forum, but I'm sure alot of you Keltec owners who are satisfied with your  handgun purchases have wanted to sample the rifles Keltec makes as well, it's just natural.

I enjoy my Sub-2000 9mm for all the reasons it's a great gun-  compact,  quiet compared to a handgun in the same caliber, reasonably reliable, reasonably inexpensive, compatibility with your chosen handgun magazine, etc...

The trigger pull is atrociously heavy howerver.  I feel like I'm going to break the trigger everytime I pull it to fire a round.

The Keltec manual warns not to disassemble the gun to the point you're unscrewing the frame halves, so I have not.

What I'd like to know is

A-  As someone  moderately familiar with many firearms assembly/disassembly, can I totally disassemble the Sub-2000 without sending it back to the factory to reassemble?

B- What if anything can I do to lighten the atrocious trigger pull on another wise pretty decent rifle?
