The rifling in the barrel marks the projectile and is traceable to the gun that fired the bullet, even revolvers can be traced by bullet matches. Bad guys have found ways of retaining the spent carttridges so the the forensics guys can’t pick them up to trace. The common sense gun laws crowd have no idea of which they speak.

Plus there are tens of millions of guns in the US now, how are they going to get criminals to buy new “traceable” guns when the already holds thousands of old ones?
