Changes in version 4:
Version 4 was made entirely from the beginning. It has a dimensionally different body that now makes it easier to fit with two screws.
Trigger sear is now longer , angled, so trigger is much more sensitive. No need to hard press anymore !
Above all, the trigger is now adjustable. You can change trigger stronge by tightening of the small screw at the bottom. (Require 1,5mm hex key)
Please note, that version 4 has NO safety lever option anymore. Be carefull during gun manipulation!
