Hello Gents, I'm new to the board but have owned this A/O W/H 1927A1 since 1989. I really enjoy shooting it but have always hated the long barrel on it that makes it look like a two handled crow bar. So I'm going SBR on this old friend (just got my stamp for it after 7 months). I see some of you have done this already and your guns look great, so maybe you can help me out. Are the barrel threads the same on my A/O West Hurley barrel as the barrels from IMA and Thompson Barrels? In other words; can I buy on of these barrels, take it to a proper gunsmith and have them swapped? In addition, my cutts compensator looks like it is either pressed or screwed on; there is no pin. I see that I can buy a barrel with or without threads at the sight end of the barrel. Can any body wise me up on the barrel end I need to attach my cutts gimmick. While I have your attention, I'm looking for recommendations of gunsmiths that know Thompsons and can do this work for me. I have read post on this site on barrel removal and I think I'll stick with a pro. Cheers! T from D
