I have a new Smith & Wesson 9mm fpc folding stock carbine. Are there any new rules concerning this gun? I shot in a match today and the RO was concerned with the way I unfolded the gun. It is a 180 degree side fold and he said I would be "spraying the barrel". Which is true. However, the gun is made so you cannot have a round in the breech and be able to fold or unfold it. He also wanted me to have a flag. When the gun is folded the breech is fully exposed. The flag would fall out while handling.
