imagine we are on frictionless surface and we have a gun.in our frame we are initially standing so momentum initial is zero but after we fire bullet we will see bullet moving.so momentum is not conserved in our frame.why?

In "our frame", the gun will recoil, so momentum is conserved. the reference frame of the GUN is a non-inertial frame,that is why momentum is not conserved
