Pardini SP Trigger Adjusting Question

Posted by mako on August 27, 2001 at 02:42:27:
Shot my new Pardini SP for the first time today. (Very nice! I like it's more rakish grip better then the Walther GSP's more upright grip. Shot tighter groups with it as compared to the Walther. It however doesn't quite have the overall wonderful precision feel of the Walther.)
The pistol arrived with a very long and heavy first stage. Following the manual, I was able to shorten the first stage travel but I can't seem to lighten it enough. Any suggestions?

I have also shortened the first stage, but I have not reduced the first stage weight. According to the manual, the screw marked PP should be turned anticlockwise to make the first stage lighter. Did you adjust this screw?   RML

The manual says only use 1/4 turns and I've turned the PP screw many full revolutions with hardly any effect? It also says that when adjusting the first stage travel that you might have to reset the sear ... but it doesn't say when you'll notice the need to reset the sear ... I guess when it won't hold the trigger and auto shoots!?! A little scary...

Sounds a bit strange that you had no effect when turning the PP screw. But, off course, if you want a very light first stage, then the spring may have to be replaced. You should measure the weight of your first stage to find out how many grams it is before deciding.
When adjusting the CP screw, you may have to readjust both the sear engagement or free play by adjusting the screw PG. If the sear is not properly adjusted, you will notice in one of two ways:
- If the shoot breaks accidentally when you take up the first stage, then you are on the edge of auto-firing (actually I do not know if the Pardini will autofire, not all pistols do). You may also notice that it feels kind of "sticky" if you take up the first stage, and then release the trigger again.
- If you do no longer have what in TT vocabulary is a "crisp" let off (in my vocabulary: A terrible(!) trigger), then you also may want to adjust screw PG. This is when you feel that there is still some movement after you have reached the second stage (rolling trigger).
Just remember that if you adjust the screw PG for sear engagement, then only a very small movement is enough to make a difference on the sear engagement. Also remember to measure the total trigger weight after adjusting the sear engagement, because the second stage weight is affected by the sear engagement.

PS. The screw Roland referred to (PS inside CS), is for the second stage weight.

I suppose I had such a tough time finding this screw that it just stuck in my mind. Sorry about that!
Let’s not even mention my first several hours. I was looking at the diagram of the GPS and wondering where all my adjustments went!

Mako, look at the screw again. It is really two screws in one. The "outside" takes a screwdriver but it is hollow. A small hex wrench goes right down the middle and controls the first stage spring weight. It only took me three weeks to find this.....

My manual says that screw is the second stage let off weight...

The manual is right. It seems that in some cases, the spring for the first stage is rather strong. I too the adjustment screw for the first stage right out oh the gun on my Pardini, and it was still on the strong side for my taste. Should be possible to change the spring, though.

Hi Mako,
If you take off the grip, you can see how the screw "pp" adjusts the 1st stage weight. I took several turns out of mine. You should also be able to see when you are at the end of the adjustment range (I'd seriously recommend removing the grip if you are planning to move "pp" any significant amount). My 1st stage was too long (for my finger) so I shortened it as well.
I did see an SP with a slightly different set of trigger adjustment screws (I didn't see the screw hole for the "pp" adjustment), but it was a little bit older than mine. it had a really light first stage, but I don't know if it was the same mechanism.
I don't know if you can replace that spring. I believe it's the sear spring and if it's too light the sear might not return if you released the trigger without firing.
Good luck with the SP, I love mine.
Steve.
