How to ID 1000g versus 1360g GSP single stage trigger.

So I got a used LH GSP 22&32 setup, great condition with lots of accessories and all paperwork.

It came with 3 trigger groups, 1 is a dry fire trigger, 1 has a 1360g sticker and the other has no sticker. I assumed the one with no sticker was the 1000g group for the 22 but even with the trigger weight set screw back all the way out its still at about 3 pounds. So its possible I have 2 of the 1360 groups but was hoping to confirm this. The hammers appear to be the same. Are there any other ways ID them visually if the stickers are gone.

Another thing I've noticed, the 5 shot dry fire unit works great but it is super tight fitting in the receiver. It's so tight I can't seem to get the barrel to slide on and lock into place and I don't wanna force it. Makes me wonder if they're meant to be fit to your receiver. The 5 shot function is pretty neat. Honestly I don't dry fire much at all but I'm trying to learn the ins and outs of this pistol.

Greetings,

The 1000g and 1360g trigger groups are identical.

The UIT has made all trigger weight 1000g so the 1360g is a curiosity now.

To shoot the NRA CenterFire matches, adjust both trigger units to 2.5 pounds. This way, you are shooting the same trigger for 22 and CF events.

Be sure to put some nail polish on the adjusting screw slots as a witness that nothing has moved over time.

Same advice applies to the Single Stage and Two-Stage trigger units. Not sure which you have.

Cheers,

Both are single stage. I think I backed out the small set screw on the lower/back of the group as far as it will meaningfully go and I'm still at 3 pounds. Is there another adjustment I should try? I would be much happier with 2.5 pounds.

Greetings,

I cannot trust my memory on this one.

I always get the manual out and follow Walther's process for adjusting.

The manual is rather well written.

Cheers,

I'd recommend getting the newer two-stage trigger units. Those are great triggers.

It's been a long time since I shot one of those old-school single-stage triggers with the bottom mount.

I don't remember them being bad, necessarily, but that was several decades and many hundreds of thousands of rounds ago.

I emailed Earl at the Walther US repair center. 

He said on the older single stage triggers that they are identical except a spring that makes the trigger either a 1000g or 1360g trigger. For $65 they will convert the trigger to a different weight,,, expensive spring!

He also said that the newer 2 stage triggers are the same except for how the adjustment screws are set. So sounds as if you don't even have to change a spring, just tweak some screws. He also confirmed that the 1000g trigger will run both the 22 & 32, his web site makes it appear that the 1000g won't run the 32 but this is incorrect. 

With all that said, I'm buying a used 1000g 2 stage trigger from one Jon's friends.

I was turned off by them long ago when I was going to replace all the o-rings in a CP2 and they told me they wanted $10.00 each for every o-ring!

I need to get into the O-ring and spring business lol.

why not call walther umarex or larrys guns?

I might get in touch with Larry's. Would be nice to have both a 1000g and 1360g single stage trigger, its a waste having 2 of the same trigger.
