Thanks!This is what it is. Knowing who makes what and how they make it is part of this game. Manufacturers will label their springs, generally, but lots don't. Just says "TM upgrade". Which can mean metal not plastic slide, but that is not always the case. The Guarder hammer spring set is made for TM trigger groups with aluminum slides.
As a rule when I build G17's is to start out with WE G17 spring kit because they are made for heavier slides than TM. I bought as many garder leaf spring, guide rod springs I could locate because they are awesome. You start with the WE strings and then fix nozzle to packing compression to raise/stabilize fps. Once stable you can raise fps by bending hammer spring, or different tighter/longer inner barrel.
Now I have six G-series.
I don’t have any WE parts lying about but I’ve gotten that advice earlier and it seems sencible enough.
Problem is I can’t fint any supplier in Sweden that sells the WE spring guide. Overall seems hard to find, and I don’t want to buy a complete gun as I prefer building on TM.
I usually just buy Guarder parts from rainbow8.
Do you have any tips on where I can order the WE springguide?
Seems like a good idea to keep a small stash.
