Thanks Antoni, you’re right, I’ll get it tested. With a new cartridge installed there seems to be good power, pellet at 10mtrs fair smacks into the target and board behind it. Like I said, still has a POI of 2 inches below the bull with the rear sight adjusted as far as I can. Hope there’s someone with one of these pistols that will tell me if they have come across the same problem. Will get it tested before tampering with the front sight. Thanks again.
