Tanfoglio GT-380

Question
I, too, have one of these, and am trying to find 1) a takedown guide; 2) a
recoil spring.  The slide is incredibly hard to pull back to chamber a round...
it just can't be right.  

Any suggestions?  Thanks.

PS- Did you work out your feeding issue?  Mine always jams the last round in
the mag.

Answer
A gun digest Assembly and Disassembly guide for auto pistols would be your best bet. It has full take down on 100's of pistols, you'll love it...check ebay or Abe books, used one is cheaper and just as good. As to springs Sarco or Gunparts(Numrich Arms) should have the spring.  Thanks.
