I have an Auto 5 in my shop with this problem. The trigger is hard to pull. I checked for worn or broken parts, but all parts look good. I found the safety bar by the trigger sear is not releasing because the bolt is not going forward enough to trip the trigger release. I unscrewed the forearm nut a couple of notches and the bolt and barrel moved forward and trigger pulled was easy again. Is this a safety to keep the gun from firing if the forearm is too tight so that it won’t crack it? Thanks for your help.
I’d look at the fore end wood. Sounds like you have a problem there with the inletting either being damaged or crushed.

That is an internal safety to keep the firearm from firing before it is locked up. Look to see if the locking block is engaging the full distance. Also look to see that the forearm is not new or a replacement it may need to be fit so the barrel returns forward to its correct position. DO NOT BACK THE MAG CAP OFF AND SHOOT IT. THAT IS A SURE WAY TO BREAK/SPLIT/CRACK THE FOREARM.
