Trigger Happy

I've just finished printing the handgrip and trigger for my Milestag gun. The trigger slides on a raised section on one of the halves of the grip. It's a bit tight and I need to reduce the size, but I've managed to make it slide by sanding the trigger down and lubricating it with PTFE spray. Three self tapping screws hold the two halves together and there are four holes to mount the grip to the gun body.
