I recently acquired a used GP-160 (Blu, 6-inch half lug barrel). The hammer pull was pretty stiff but seemed to work well.
I replaced the hammer and trigger springs with lighter ones from a Wolff spring kit.
The pull is in fact lighter but now there seems to be a quirk when the hammer gets to the cocked position. It takes an unusual strong force to finally cock the hammer and a lot of trigger force (single-action) to release the hammer. Basically the same with double-action pull also.
One thing I noticed which I hope is a clue is that the original trigger spring is 18 mm long. The Wolff springs are about 22 mm.
This particular GP-160 was made in 1996.
I also have a 2006 KGP-141 and the spring upgrade went very smooth. Its original spring (stock) was also 22 mm.
Is it possible that older models required a shorter trigger spring and that the longer spring is too tightly compressed when reaching full-cock?
Or does anyone have any other suggestions?
