Guys, I need some help. I went to the Albany gun show today. I hooked up with JC and Coctailer and got myself a long awaited SIG P229R and a Glock 19 (to replace one that I sold). The SIG was in .357 caliber. I wanted a .40 but JC didn't have one on hand. JC said I could order a .40 barrel and swap it out....having two guns in one. When I got home I prepared to clean/oil the gun but I think I may have made a mistake? Is there a way to tell if the SIG is DA/SA, DAK or DAO? I wanted a DA/SA...but I think this may be a DAK gun...which I don't want. Any help would be appreciated!!!
