HELP with S&W 422 problem!

[Ruger-Jay]

I've never had any problems with this gun until last weekend. The gun fires the first round and cycles but will not fire the second round. Upon disassembly (which I have done before), it appears the disconect is not working properly. When the trigger is pulled, the sear is pushed releasing the hammer. The problem is that as long as the trigger is held, the sear is not resetting. When the gun cycles, the hammer is not resetting because the trigger has to be released to rest the sear. Can anyone help with this problem? How is the disconnect supose to work? Could I be missing a spring somewhere?
Thanks... and no, I won't sell it cheap!

Well, it's been too many years since I had a 422 apart to tell you how it works.

I seem to recall the disconnecter is just a flat plate pivoted off of the safety lever pin.

I would think it is probably just full of dried oil and powder fouling.

I would take the grips off, and hose it out with WD-40 while working the action, and disconnector up & down.

After that, blow out the WD-40 with an air hose, and re-spray with Rem-Oil spray.

If that don't help, I don't know what to tell you.

If you don't let off the trigger to allow disconnecter reset it won't reset by design. No semi-auto will reset while your holding down trigger. As soon as you let up you hear a click and the disconnecter resets Right?
I think they call any other way of functioning as a machinegun or a malfunction.

Sounds like he is saying that the hammer is following the slide down, failing to cock.

If nothing has been disturbed, dirt or grease might be the problem. But that is one of the most fiendish guns ever designed for detailed dis/re-assembly (with the possible exception of the Model 61 Escort). For one thing, there is no disconnector as such. Like many other pistols, there is just an arm on the trigger bar that is pushed down by the slide to disengage the rear end of the bar from the sear. When the trigger is released, the arm can come back up into a cutout in the slide and and the rear of the bar will re-engage the sear. The trigger spring powers both the trigger return and trigger bar upward movement.

There are a lot of parts and I am not sure I recommend the user get into the mechanism if the work involves anything other than cleaning with a spray.

soak it in white gas and clean, look for a broken wire spring and worn sear engagment surfaces
