Hi folks,

Looking for ideas on what to look for on this gun.

- It has been cleaned thoroughly
- the problem presents with different mags both factory and promag
- the problem presents with different types of ammo including high velocity
- I had a different gun that worked fine with the same mags and ammo (but I no longer have it)

- first round from the magazine being loaded by working the bolt manually - feeds fine, gun fires, ejects the casing and picks up the second round
- the trigger is dead and remains pulled to the back
- working the bolt manually ejects the unfired round and picks up the next round from the magazine, the gun can be fired, the casing will eject, next round will be picked up but the trigger is dead again and so on until the mag is empty

Any thoughts what else to check? I'm thinking of pulling the buffer off and seeing if it will function... Anything else I can check?

I've never had an issue with my 597, but curious if it has something to do with those round pins that the bolt runs on. Sounds like it's not going back far enough to reset the trigger, but far enough to drop and pick up the next shell.

I don't tighten those set screws on the back of the action that holds those pins in place, I put them snug then back them up just a bit to let the rods 'float'.

I can take pictures tonight when I get home if it doesn't make sense to you. My gun does get quite dirty back there and I try to keep a small amount of light oil on those rods to keep things running smooth
 
Check the two screws on the back of the reciever that hold the bolt guide bars in place. If they are too tight the bars can bend slightly and cause the bolt to not go far back enough to #### the hammer. They should only be finger tight, dont torque them down at all. They wont fall out when the stock is on cause the stock blocks them.
 
Appreciate the suggestions to make sure the bolt guide rods are loose. Thanks guys!

Do not appreciate all the suggestions to clean and lube - I stated I cleaned it thoroughly in the very first line of the post. Did you actually read? :p

While getting dirty is usually the first problem of all semi 22 guns, this isn't the case here.

Yes, but "thoroughly" can be interpreted differently by both the reader and the poster. Was the trigger group disassembled and each part cleaned and inspected? Or was aerosol just sprayed willy-nilly with a pat on the back for a job well done? The ammo seems to be doing it's job, the mags seem to be doing their job but the hammer is not cocking and the trigger is stuck to the rear. I suggest you disassemble and go thru the trigger group and clean what needs cleaned, inspect all the parts, then reassemble while lubricating surfaces and pivots.
 
Pull the trigger group out of the receiver. See the little arm that sticks up? This is the disconnector lever that prevents the gun from going full-auto. When the bolt comes back it knocks down this lever which pulls the sear back to allow the hammer to catch on it and prevents the trigger from releasing the sear until you let the trigger forward again so the linkage can pull back down from the spring and re-connect the link between trigger and sear. In my pic here, you can see I forgot to hook up the reset spring to the little cross bar after cleaning. Doesn't matter, this is a spare parts trigger group for me now, anyway. Point is, focus your attention here. Did you forget to hook up the reset spring? Is the linkage gummy/sticky? Is there slop in the linkage not allowing reset for some reason?

 
I had a similar experience with my 597, it turned out to be the rubber bumper. Excessive cleaning caused the bumper to swell, which prevented the bolt from traveling back far enough to properly cycle, causing jams.
The gun would feed fine manually, fire, then stovepipe the spent round. It took me a while to figure out what the problem was.
Replacing the bumper cured the problem and the gun has worked properly ever since. (5years)

It fires and ejects, hammer is cocked by the bolt but the trigger doesn't reset.

I removed the buffer completely - no change.

Thanks for that picture. The spring is hooked, but looks significantly different from yours (longer, thinner) makes me wonder if it was lost and replaced with something close... Looks like that is the issue - nothing pulls the trigger to the reset position after I take my finger off. Working the bolt resets the trigger by hitting the reset bar...
