Don,
I have had a few single trigger Repros and seen and heard of many others that functioned flawlessly. Most often we hear of the ones that act up.

Not to take away from Dan May but Richard Skeuse has given good advice as well. After all, it was his family that facilitated the production of the "Parker Reproduction by Winchester".

I only have two repro's and I have not had any problems with the single trigger (knock on wood :) )

I agree with Dean, the man that Richard recommended I did not know about (but I did write his name down :rolleyes: just in case) but he should know since it was his family that produced the repro's

Dean and Eric, Chris Maest was a Krieghoff factory gunsmith who has worked on my Krieghoffs. He is now a Krieghoff dealer and still works on them. I suspect that Chris worked with the Skeuse family as a troubleshooter and parts (especially barrel) installer during the early days of Repro production. Chris is the proprietor of Clay Target Sports in Princeton, New Jersey. He has a website, but don't look for references to Parker Repros on the site.

I've also had dealings with Chris and he is a top notch guy.

We have 3 repros, all ST, and the only problem was with son Wyatt on the 20 or 28 doubling, I don't remember which. Guns had been apart for Brad B's work so it wasn't an old grease issue. We finally figured it was Wyatt's enormous gloves used for winter league (it gets mighty cold here). It seems they filled up the trigger guard enough to cause the second barrel to go off almost simultaneously with the first. No problem with the gloves removed, except for cold hands. He switched to slimmer gloves and the problem went away.

Repro Single Trigger
 

Classic Gunstocks bought out the Miller Single Trigger Company from Doug Turnbull. They may be the place to start. Or, you might try Larry Del Grego in Ilion, NY.

I think the repro single trigger is a copy of the Parker Bros single trigger which was developed in house by PB. Larry Del Grego, the prince of Parker repairs, just might be able to get it done. 315-894-8754.

It wouldn't hurt to talk to Larry and ask. I don't know how knowledgeable the CG people would be with non Miller triggers.

You might also contact Doug (?) Skeuse at Reagent Chemical Company, a division of White Flyer targets. He was the lead guy in making the repro in 1983. He might have the design schematics for the trigger.

John, Richard is the son of the founder of the Parker Repros, so I would think he would be able to steer someone to the correct smith.

Last I heard the Del Gregos were declining to work on Repros, have things changed?
