Had anyone used any the CGW's trigger springs on a Tri Star T-120 ? And what was the end result in actual trigger pull / breaking weight ?
If you are talking about the Trigger Return Spring,
https://cajungunworks.com/product/8-trg-return-spg-oem/Yes, I made the swap once on my P120. The CGW spring's has a slight different design, but after many rounds with it, I never really felt any differences with it and the OEM spring, so I removed it and is now set aside as a back up spring, as some have mentioned the spring possibly breaking with use, but nothing happened to my Canik, nor CZ return spring so far.
