Yes you´re right but i have to stay with the TPX as stock as possible cause of strange laws down here. It´s mostly made of free material and my main Goal was to check if the slide grap mech will work.
It is possible to to get the slide more Slim and also the TPX Frame in the cartridge area but if i would do this i can only Transport my TPX just in parts, cause of the laws done by noobs !!!
