Welcome to the forum. It sounds like you have a great collection. Can we see a pic?

won't one group work for all 3 ?

The GSP and GSP-C share a trigger group. The OSP uses its own trigger group.

And would they all be 1000gr ? Single stage triggers if that helps.

There are a variety of trigger groups available with different pull weights, some with a single stage trigger and some with a two stage trigger.

The 22short is marked 200 gr trigger. There is a 1000 and 1360 gr set(in the gun) and a training trigger. Two mags for each caliber and the original case with the key. All the paperwork and small tools that came as new. Cant find any handling marks on the metal and there is no staining on the grip from palm sweat.

 

Welcome from Northern Indiana, enjoy the conversation.

 

Very nice. The IA proof on the GSP-C upper dates it to 1980, the same year as my GSP. Let us know how they shoot for you.

 

Nice to know thanks! Early stuff is usually better made quality. Any idea what a replacement trigger group might run?

 

The old DSB & international rules had the OSP trigger weight set at a minimum of 1000 gr and the .22 l.r. Spopi at 1,360. That is why the Hammerli International has a little screw with a pivoting spring, the trigger weight can be changed to be optimal for both disciplines.
The rules were changed later.
