Thanks for the advice, the thing is I'm not sure if I will be able to do the job myself, I'm just starting and never even imagined till some days to make a modification to a weapon, even the slightest like this one. Have some of you made this? Is there any danger in this polishing of the ears? How skilled one has to be to do it without having a high risk to spoil the gun?
