Having problems with decocker/safety, pistol will not recock once i decock it and had accidental discharge at friends range when charging pistol, any fixes, this started after changing recoil and hammer spring. Thanks!

Sounds like you reassembled it incorrectly. Make sure the hammer strut is sitting in the right spot.

Thanks i'll try to redo that part.

Let us know how it turns out.

Welcome to the forum JK.

I have tried disassembling the pistol and taking the hammer strut out, and putting it back, I think it is something to do with the safety. Any ideas, otherwise i think i will have to part it out, it is a 1968 model my son has a 1974 that is flawless.

Maybe take a look through these. You might figure it out.

Thinking out loud here. When you put the lever into 'safe/decock' a bar swings up and blocks the hammer from hitting the firing pin. I can't figure how you could PUT the weapon in decock and get it to discharge unless that block was 1) not raised (completely?) or 2) something is broken. Looking at the (removed) slide, when you move the lever from 'fire' to 'safe/decock' do you see this happening? If it is, I got nothin'. If the blocking bar is NOT moving seems to me that the problem lies in the safety assembly itself. I think you might want to look at your and your son's slides side-by-side and see the difference between how the 2 operate when the lever is rotated.

If yours is hard to move (and you BET I've had those!) and not rotating all the way, it might let the hammer strike the FP. Better cleaning and lubing might take care of it. But I'd do some comparison since you have a functioning model to use for comparison. Good luck.

I think he was saying that it accidentally discharged while he was trying to manually cock the hammer. Meaning that 1) the was a problem with the trigger bar not contacting the hammer to begin with; 2) the sear was not in place to hold the hammer back once cocked. Again this is while he was trying to manually cock it, so the safety would be on the fire selection. That, in my head, points to a problem with how the Disconnector interacts with the Sear and Trigger Bar. Meaning that something got misaligned or loosened while he was changing springs. So he needs to go back through the assembly manual that I linked and make sure everything is in there right. It would probably be a good ideal to test functionality with snap caps prior to live ammo.

If that's the case then, yeah, something's not right. Wasn't there a thread about the sear hanging a bit and a mild dremel or file-work inside the slide in that area plus a drop of oil ON the sear to make it slide up and down more easily? Keep it from sticking? This is getting outta my depth....

Thanks for all the advice, I've tried all you've suggested, I think I'm just going to have to part that the gun out, I don't trust it and I don't want someone else to get hurt with it.
