I hope and pray Remington never exports Handi production. When I got my first Handi, the .45-70, I sent the frame in for 3 more barrels. Since then, I fitted those barrels to their own frames, and just finished fitting a 7mm-08 barrel to a 1995 frame. It locked up perfectly, just needed a slight shave on the latch shelf. I guess I've fitted about eight or nine now without any problems. Personally, having done it both ways, I believe buying barrels on this forum is the better way to go.....time and cost wise.
