I recently bought a used (new for my 34 year old son) Glock 21. It came with a Lone Wolf barrel (black, no logo) threaded, with a compensator. It also came with the stock Glock barrel. Since the Glock is intended when we attend a Front Sight course in October I put the stock Glock barrel back in the 21 for his use. My intention is to use the Lone Wolf barrel and compensator with my Glock 21 for reloads (no lead yet, just FMJ). Since a have a stock length, stainless LW barrel I was at least reloading correctly for the barrel and my reloads chamber in the new black LW barrel and it shoots quite nicely. My question is around set up. Do I need to Loctite the compensator threads or set screw? Is there anything else I should be concerned about?
