.25 walther falcon hunter barrel play

[coaxialtasko]

I have a Walther Falcon Hunter in .25. Iam getting shogun patterns (won't stay on zero,not scope) with like 20 different brand name pellets.I was looking at the barrel cocking hinge is held by pins so you can't screw it and  I noticed a couple mm of play,so I didn't know what to do so I cut up soda can and put a couple pieces on each side.Seems to be an improvement,but they look bad and fall out when I cock it. Is there any way to properly correct this                        so it works and doesn't look like a soda can?

This should be posted in the Turkish Gate.
 
The Cocking arm isn't what holds the Breech block tight. There's a screw that does that.
I've seen some Turkish Guns with worn and even missing washers that go between the Breeck block and Compression tube.
I'd check that area first.
