Well thank you my good Sir for the kind words!
I will email you when I get back home (on business trip in CA).
Question 2 U - Did you have a T01 re-fitted to you 460? TO the best of my knowledge, the last guns that went out of the Diana factory with the T01 trigger was in 2001-2002.
The 460 model is a new design, so it SHOULD, if stock, have a T05 trigger unit just like the one that I posted.
The cleanup on the internals of the T05 is pretty straight foward, unless you are modding the unit. Debur all edges and polish all contact points. Unless you don't mind messing around with "small STRONG springs", plates (arms) & pins, leave the UPPER arm in place because if you can't get it back in, the gun won't shoot. If you look at the pics, you can see the back view of the trigger with the lower arm and its spring removed...you can get in there with 800-1000-then 1200 grit abrasives, then polish with Dremel felt tip or buffing wheel and compound.
When talking about the "feel" of a trigger, well, they are all different, like different personalities. A rekord trigger of that of the TX 200 break clean and have a "feel" that is all their own...even after tuning.
A T05 trigger has a feel that is all its own, and the word feel is itself is a relative term...they can and do however get smoother and more predictable. Everybody who does triggers has their favorite lube misture...on my guns here in the desert, I use a set ratio of JM Clear Tar and Molly, with a bit of an additive that is like oil, but is still different in that it penetrates the metal parts structure and micropores at the molecular level molecular and bonds...the metal becomes self lubricating until wear removes a certain level of the metal in the part itself. I don't know the name of the product, but it was spec'ed in the US Military's SaaS program....I might be able to find a NSN for it...wlii have to look when I get home.
