When it comes to double gun maintenance, it seems to me we have double standards.
We seek and worship guns that "...have never had the screws turned...".
Yet, there are a good number of prolific target shooters into doubleguns that know Perazzi and Krieghoff guns, to name a couple, recommend regular servicing.
So a 70-80 yr old single trigger (or 20-30 in the case of the Repro) starts acting up, after no maintenance for no one knows how long, and it gets a bad rap for its design, or more commonly, single triggers get lumped into one bucket and deemed all as unreliable novelties.
If you've ever openned up a 100 yr old gun "...with screws that have never been turned.." you know where I'm coming from. These pics are an example of a gun I openned a few yrs back.
After seeing this, I was surprized it functioned as long as it did, until I had a problem.
OK, I'm done

I mean no offense, but rather intended to put some perspective on this issue and maybe start a dialogue.
