[HK SD9 Tactical]

I had thought of that, being that I was planning on sending it off to Hi-Desert Dog anyway. Maybe I'll drop him an email and see what he thinks of that.

The barrel I sent to him was one that was cut at the blind pin so it does not matter if the barrel is cut or not.

If you do not want to keep the barrel and flash hider in its original condition, from what I have read, it is easier to cut it than to drill it and try to unscrew the flash hider (especially if the firearm has been fired). There are speciality tools that you will need to put the amout of torque needed on the barral/flash hider to get it to unscrew. I would not chance damaging the receiver (twisting it) trying to unscrew the barrel/flash hider.
