Doubling?
 

What can you guys tell me about doubling with a single trigger gun?

It hurts.

If it's a Repro, try cleaning the action thoroughly. The inertia block may be gummed up.

I had a 20 reproduction that doubled. After having my local gunsmith do a thorough cleaning, the problem persisted. I sent the gun to Heritage Gunsmith, 740-625-6131. They handled the repro repairs for Jaques, who distributed the reproductions. Heritage completed the necessary repairs and trigger work for me at a reasonable cost and time. No problem since.

Just arrived home from a few days away which included a couple of rounds of 5 stand using my ST 12 ga. Repro.
Best part of my break away was catching up with a few 'long lost' friends ... worst part, my gun 'doubled' twice during the 50 target shoot.
The shells used were 1170 F.P.S 1oz loads and it's only been about 300 shots since my local 'smith cleaned the action internals and dis-connected the auto safety. ( During this time the gun has performed without fault. )
For about the last 6 months I have been using a Beretta U/O for my target shooting and I suppose I have grown accustomed to the trigger on the Beretta and found the Repros trigger to be extremely light in comparison, so much so, that a few of the early targets escaped due to a premature trigger pull.

I wonder if ... The gun needs to go back to the 'smith for a more thorough clean, or if the doubling may have been my fault on the trigger, or if it's possible some other problem exists.

Need to get on on top of this one, starting with some experienced advice from fellow Parker Gun enthusiasts.

When my 16ga doubled I sent it to DelGreco and it turn out to be a worn sear. He took care of it with no problem.

The old single triggers had to have the correct tension between the two tang screws. Check to see if the tang screw under the top leaver and the one under the trigger guard bow are indexed. That cures most single trigger woes.

Are there any tricks to take the triggers out of the Repros for cleaning?
