Airhawk safety issue

[124nut]

I recently bought a ruger airhawk. The stock was scratched all up so I refinished it first, it turned out nice. ( Sorry I don't know how to post pics. ) I chronyed it and it was only 650fps. I looked to see if I had a spare 34 spring but didn't have any. I did find a new factory spring that came out of an RWS 52\ .25 cal. I put this spring in my gun til I get new one ordered. After firing about 20 shots I chronyed it again and it shot 880 fps with the 52 spring. Now for the problem, the safety doesn't work. I can fire it while its on safe.
Does anyone know how to fix this ?? Thanks,

There is a real trick to getting the safety back in place on these models.  Once the part is removed and the trigger parts are moved any amount at all, those parts get moved off center inside the trigger assembly.  I use a small, thin seal pick to get the parts lined back up.  This involves pulling the trigger back so you can align one of the parts and then releasing the trigger to hold it in place.  Hope this helps.

you may have more spring length than needed, could be coil bind before the safety is pushed back to engage..

A test for Mike's idea.    After the rifle is cocked can you manually pull the safety back further so that it engages the trigger and makes the gun safe?

Might have to give it a few wiggles and jiggles to get it to slide further back.

Yes, I can pull the safety out after cocking the rifle but it still does not work. Ill try to get everything lined back up. Thanks all,,

the safety blocks the trigger with a leg that hangs down, make sure it moves freely..

The safety is pushed on by the over-travel of the piston rod as you cock the rifle.
It can be stopped working by such as a top hat fouling on the mouth of the rear spring guide or by such as being coil-bound. i.e both conditions will stop the piston rod travelling rearwards sufficiently to push the safety into the on position.
If, however, the safety is engaged but the gun still fires then Mike has the answer. The rearward travel of the trigger is blocked by a leg that hangs down from the safety striking against an upstand to the rear of the trigger.(see schematic link) https://www.pyramydair.com/air-gunsairsoft-schematics

It is for this exact reason I recommend makeing two drift pins to replace the cross pins while disassembling and reassembling the Diana springers. Saves a lot of hassle and headaches rebuilding the trigger unit as a whole.
