Cleaning Pardini SP trigger group

[jabberwo]

I've noticed the trigger pull on my Pardini SP (an older model) has gotten a little heavier. Before I just adjust the screws, I wondered about cleaning out the trigger group. NO manual I find for the SP talks about it. Nor does google find anything. Anyone ever attempt it? What did you use? Any tips before I dive in?!

thanks,

I have shot an older Pardini SP, ca. 2003 versio, and have never needed to touch the trigger group. Unlike myn older Wlather GSP which has a removeable trigger I am retiscent to do anyh work on the Pardini trigger.

I just blow any dirt or powder debris out using a "duster" can from a photo store. My wife's has about 10,000 rounds through it, and it has never had any issues.

Before you start tweaking the trigger settings, remove the grips and bolt and then flush out the guts with Tri-Flow. Be generous and hose it down. Then, blow out the excess T-F with compressed air. That will clean off the crud and smooth the trigger. Repeat about every 2500 rounds.

I went to practice today, and my Pardini SP New trigger started acting up occasionally during sustained fire. After firing a shot, the "recovery" of the trigger felt rough, and the 1st stage of the next squeeze felt the same. What's worse, it then failed to fire. At first, I thought I hadn't allowed the trigger to go back far enough (which I haven't done in 20 or 30 years). Deliberately releasing the trigger again worked once, but not a second time. Pulling a third time finally got it to fire. This would be very nasty in a match, because if I called for an alibi, I bet it would fire when the range officer tried it. It acted up only twice in 60 shots.

Dry firing felt OK, and a visual inspection didn't how anything obvious. It didn't appear to be especially dirty, and I had blown out the trigger section the week before with compressed air to remove loose powder. It worked fine in a match a few days later.

I took it home this evening, flushed out the hammer/sear area with TS301, and then blew it out with compressed air. I put a tiny bit of grease on the hammer, sear and trigger bar pressure points, and it feels fine now. I'll take it to the range tomorrow for a quick test. I have a match the following day.

Nothing appears to be physically broken. I can only hope that a bit of dirt got someplace critical, although I can't figure out where it would have been to produce the symptoms I experienced.

Has anyone else run into this problem?

Thanks!
