I want to refinish my new M92, but am concerned that the serial engraving may be too shallow for sand blasting. Has anyone tried this yet?


Thanks

Well it shouldn't be that shallow or you are really using some serious grit at high pressure. If you are worried about it tape it off and when done blasting the rest of the gun pull the tape off and hold the nozzle back off the receiver a bit and lightly make a pass or two on it. If you are removing enough metal to remove serial number I suggest you back off the air pressure and use finer grit.
