Recent correspondence with the illustrious Mr. Oliver:
Hi Chris,
The internal Trompo weight ring fits exactly on the Torpedo between the cap and body. This makes the cap fit great. I just tape them together (the metal ring is under the tape). I will start shipping them that way immediately. Much better than gluing them together and using an Oring for extra weight.
I just sent the drawings for the QuickSilver Hybrid (no cap) and the Hollowpoint to the new maker in China. Here's hoping he does good.
YO'res,
Dale
