I bought a Galazan TG a couple years ago. It's bit smaller in the loop than either a fox or a Parker and definitely a different profile in most regards than a Parker. But it does have a long tang and is the shortest way to a long tang TG for a custom gun. The threaded stud seems to be a metric thread and needs to be replaced to match the gun.

Personally, I think welding on a longer tang and redressing the original is easier than fitting up a Galazan TG most of the time, especially if the orig TG is well made and attractively shaped. Most Fox SW TG's are crap IMO and replacing them is warranted for a nice custom gun.
