LP50 Shoots Fine, But Doesn't Cock When Dry Firing?

[Gwhite]

I dusted off my LP50 to practice sustained fire. I haven't fired it in quite some time (over a year?). It works fine with pellets, but I tried the dry fire adapter, and I get one "shot", and that's it. I have to re-cock it manually after each shot, and when I do, the adapter advances 2 shots worth.

I don't know if the lubrication is getting sticky with age, or if something else is going on. I put on a full cylinder, and that didn't help. I'm not sure how the cocking process with dry fire adapter works. If it relies on back-pressure, maybe it's leaking too much?

Any ideas or suggestions? For now I will just shoot pellets, and see if that loosens it up a bit.

Thanks!

I recently purchased a used LP50 and was having the same issue with it not cocking or cycling after most shots. I reset the trigger group per Steyr's online video and it's working fine now. Good Luck.

It's probably dried grease in the trigger unit, I'd give it a clean out and service.

I haven't tried to dry fire mine recently. It hadn't occurred to me that the re-cocking process is partly determined by how easy the back pressure can reset the trigger, so cleaning & lubrication makes sense.

I found the following videos online on the LP50 trigger:

https://www.youtube.com/watch?v=lT8h3_2eCrc This is from Steyr, but it only talks about adjustments, and doesn't describe removing or cleaning the trigger.

This Steyr video on changing the trigger weight spring: https://www.youtube.com/watch?v=hAgiA-JIeOA covers removing the trigger assembly. The second half appears to be a duplicate of the trigger adjustment video.

I couldn't find any info on cleaning & lubrication, but I can certainly pull out the trigger assembly and give it a try. My first guess is to blow out any dust, and hit the moving parts with TSI-301 lubricant.

Thanks to everyone who responded!
