Bolt lift mod part of a T&T?

[82boy]

So I was wondering if a fully machiened insert was part of the T&T.

Nope, just a 38 special case. Why do you need something machined? Just because it fit loose doesn't mean its not going to work, the question is why does it matter? There is no place for it to go, and a machined piece like Stockaid makes doesn't work any better. Sometimes tight fitting parts cause more problems than they fix, and sometimes looser is better. SSS has T&T hundreds of actions, and use this same thing on all of them, if there was something wrong with it, they would know, and would not use it.
