I recently got myself a WE G17 (Gen 4) because I could not for the life of me find a TM G17.
With regards to the upgrade parts listed in this amazing post, I was wondering how many (If any) of them are compatible with the WE G17, particularly the Gen 4 version? I've been looking to see if I could eventually change things like the slide and the inner-barrel and perhaps putting on one of these attachments (
