Thats Looking great well done, I would agree with Mr P that it can get quite hot in a Patrol Tooper but if you are not in a warm country it can be a blessingπ as for the pants if you can do this for the jacket they should be a fly in the night.
I have been thinking about ways to keep the blaster secure in the holster. I plan on sanding down the trigger and replacing it with a magnet the same size then have a corresponding one in the boot.
It does not say it should be black it also does not say it should be white. You can direct your GML to this thread if they have questions.
