Blue Loc-Tite isn't permanent.
Humm. The Comp does have two set screws. Still not sure how well the thread holes will hold up with frequent removal of the set screws. You got me thinking that I should call the manufacturer and get their advice.
On a semi-automatic pistol?
I cannot remove the barrel from the slide since the compensator is semi-permanently attached (blue locktite and set screws).
There are 2 powders specifically formulated for comp guns. Auto Comp works best in semi autos. Power Pistol is better for revolvers, as it burns cooler, and you don't get burnt on the cylinder doing reloads. It works fine in autos as well.
