I have. Ed is a great guy to work with. I had him do my PS90, however, he couldn't salvage my OE barrel/hider, although he tried. Called me and let me know, and I gave him the 'go ahead' to cut. Keep in mind, my PS90 was far from 'new' when he got it, and he has more success with the drill-out on a new(er) one. Aparently, according to Ed, the locking compound they use hardens up with use.pike3 said:Has any one used HDPS corp to work on the ps90 barrel replacement and pin drll out?
