D Johnson Posted February 26, 2020 Report Share Posted February 26, 2020 Hi All I’ve a 522 swat model I’ve owned from new, probs no more than 500 rounds through it. Trigger has never been great to say the least and has from day one occasionally showed a problem when initially cocking and chambering a round, you go to pull the trigger and it pulls through it’s entire travel but fails to release the hammer. Trigger feels totally dead or disconnected, action taken was to re cock and carry on. I thought things would loosen up after a bit of use but the problem is still there. Just wonder if any other 522 users had experienced anything similar??. Also any ideas as to any improvements to be made to the factory trigger units operation. cheers Quote Link to comment Share on other sites More sharing options...
Andrew Posted February 29, 2020 Report Share Posted February 29, 2020 If you can cause it to happen without chambering a round, break it open and see what it is doing. I am not familiar with the kind of trigger arrangement the SIG has but it sounds like a bad disconnector.~Andrew Quote Link to comment Share on other sites More sharing options...

I’ve had it open and manually cocked the hammer loads of times to try and duplicate it and have studied the release etc when pulling the trigger to try and identify any irregularities. I’ve a couple of options left but as I said initially I was curious if anyone else had experienced anything similar. cheers Dave Quote Link to comment Share on other sites More sharing options...
Andrew Posted March 1, 2020 Report Share Posted March 1, 2020 Since the hammer is cocked, and not following the bolt down, I would think it is the disconnector. or disconnector spring. I'm not sure if you have opened it up at the actual time of failure but often things happen on firing that can't be replicated manually. Next time it does this on it's own while firing, open it up and take a look. I tried to find a decent schematic of the trigger yesterday but couldn't. It's a puzzler.~Andrew Quote Link to comment Share on other sites More sharing options...
Andrew Posted March 9, 2020 Report Share Posted March 9, 2020 Dave, Did you get it sorted out??~Andrew Quote Link to comment Share on other sites More sharing options...
The Burpster Posted March 11, 2020 Report Share Posted March 11, 2020 Never had an issue in 5 years of owning mine. Very early on I bent up a new trigger spring from piano wire. Tried several different grades until I found one that gave nice even 3lb pull but still allowed the hammer to work. Eased a bend into the hammer spring to lighten it up a bit and polished the sears with grinding paste. Performed faultlessly and still is with its new owner. It’s a very similar trigger unit to the AR layout but not the same components... ☺️ IIRC there was a YouTube vid on modifying the trigger components as I did.

I may well go the route as described by the burpster at some point. I do regret with hindsight not punting it back to the dealer the first time it did it. Anyway if and when it gets sorted I’ll post it in here. Cheers Dave Quote Link to comment Share on other sites More sharing options...
