I have been considering getting a thread adapter for my Sig P320 with 13.5x1LH threaded barrel, to use a 1/2"x28RH piston. This is for an Silencerco Osprey 9. I have the 1/2"x28RH threads on my other 9mm barrels for other guns and thought this would make things simpler. The price for an adapter is very reasonable. Are there any drawbacks to consider? Anyone have any experience to share?
