is it selectable? lop adjustable? or standard bottom top firing/non selectable? significant price difference between the first two and the last. i picked up a mint standard B/T firing trigger group from MIA a few months ago for 750 give or take a few dollars.
i wouldnt do it. you can find them on ts.com all day for 500 and up for a standard trigger. richard bullard jr. and MIA post them frequently. best people to get them from as well. bought one from each of them actually.
New or used triggers will vary based on the options. I think for the standard competition models you have:
Most Expensive = Externally Selectable with MX2000 engraving = $1800 new from Perazzi USA
Next Down = P4 with MX2000 engraving (Internal selective can be an addition to these) = Also $1800 new from PUSA
Next Down = Externally Selectable without engraving
Next Down = P4 without engraving
Next Down = Non Selectale with MX2000 engraving = $1200 new from PUSA
Cheapest = Non Selectable without engraving
Internally selectable tree can be added to the non-selectable triggers. Cost is about $140 for the parts. Generally speaking P4 and Externally selectable triggers are available here for $1200. Engraved non-selectable is around $750, both of these would be in excellent condition.
Also adding SC engraving adds to the value of the triggers.
