Chris, took the trigger assembly apart last night inspected it and put it back together. It's not worn, its tight. The only thing I did different is to put the hammer pin in for the right to the left. Pulled the hammer back, pulled the trigger, hammer went forward slowly released the trigger and the sear reset and locked in place. We'll give this a try on the next range trip.
Jim, I don't load hot loads for anything I shoot. Here is a list of what I loaded. 13.0 of N110, 12.5 of N110(really bad), 15.1 of H110 and this was half good but left, 14.1 of H110, 5.5 of Unique and was pretty good at maybe 4.5" group and 14.7 of H110 that was about 5". All Berry's 110 lead round nose at 50 yds. These are the ones I have targets for.

At 50 yds, these should be giving you 2 inch groups or less. Does the receiver fit tight in the recoil plate so that the action doesn't move when the carbine is assembled?

Hey, man, great pictorial tutorial :)
photobiker; The gas piston should be free to fall by gravity when you pull the slide off of it. Take bore cleaner and drip it around the piston. Take a magnet and see if you can use it to move the piston back and forth. Don't use steel tools on the piston. You can use brass-faced pliers to break the piston loose if you have to, but once it starts moving the bore cleaner will quickly free it. Let the bore cleaner run down the gas port and out the barrel. Most are not as demented as me, but I clean it like this after any firing.
It is normal to get a dented primer on any self-loader that has a floating firing pin (no FP spring).
We know the gas port is clear and the piston is moving during firing because the carbine obviously extracts, ejects and reloads if it fires two rounds in a row. The fact that it might do this on one trigger pull makes it a 'machine gun' under the law and I am dead serious. Do not fire it again until you fix whatever is wrong in the trigger housing.

Hammer pin.......... Left to Right.
HTH,

Charlie, that side of the "trigger box" was a little wider. I'll try anything.
Inland44, I'm with you but I think most people would associcate this with a double fire you can get with a handgun because of poor grip with finger on the trigger. The magnet is a great idea. But like you said it does work.
Jim everything is snug.

Oh, a 'bump-fire'. I have gotten one double-fire like that on a Taurus 24/7 .45. The trigger is very light :) and apparently I put pressure on it during the recoil cycle as the muzzle was returning to the sightline. I've been meaning to take that one out and try to reproduce how I did it and learn to do good 'doubles'. All I can say is to concentrate on holding the trigger back and don't let off for the re-set until the shot is over. You may have a bit of a 'hair trigger' there that you just need to get used-to.

Try 4227 powder or 2400. Sounds like it just doesn't like those powders.
-
Jim. some 2400 showed up yesterday. When I get this double fire thing worked out i will definitely start working on a 2400 load with LRN.
-
Range day. Charlie that pin reversal seemed to do the trick. That is the only thing that is different other than taking it apart and putting it back together. I only shoot 12 or 15 rounds today but no double fires. As mentioned the floating firing pin does leave a dent on the primer of the next loaded round. Next time primers are available I will get CCI for this round.
Now to load up some or that 2400 and see if I can get those 2" groups. Don't think I can with those sights but will give it a try.
