Got a good deal through FTF sale on a generation 3 model 33. Came with a lone wolf .40S&W barrel along with the factory .357Sig barrel. I picked it up from him first thing this morning before work, so I haven't had much time to go over it. Externally the pistol is in mint condition. Everything internally appears in good working order, but I did notice that someone had done some polishing of a few parts (firing pin safety, and the part of the trigger bar that contacts it). The .40 barrel is in great condition. Has normal wear marks from use, but in great shape. The factory barrel, from what I was told, hasn't had more than a couple boxes of ammo through it. The exterior of the barrel has no wear marks, and the bore appears to be unused. The chamber end, however, appears to have some sort of fouling. Not sure exactly what it is, and I didn't have a lot of time to mess with it this morning. I took a large dental q-tip soaked in Hoppes #9 and spun it around in the chamber a couple times and seemed to remove part of it. I wiped that dry, put a light coat of oil, then left for work. I plan to get into it when I get home this afternoon. Question I have is, what is the best way to go about cleaning out that chamber? Can I soak the chamber end of the barrel in Hoppes #9 for a period of time without harming the black finish? I read somewhere some time ago about using flitz polish in a barrel/chamber. Is this a good idea? If so, how does one go about doing it without ruining anything? The seller included the remaining ammo that he had left after firing through the 33's factory barrel. All of the ammo is reloaded ammunition. The cases don't look very clean (nothing like new brass) and part of it is reshaped .40 brass. I don't think I'll use any of this ammo unless I'm absolutely forced to do so. Just thought I would bring it up though in case there was the possibility that the reloads had something to do with the chamber question. Thanks. Wanna kill these ads? We can help!
