I picked up a NIB SA Loaded Champion last week. I did my normal cleaning and lubrication before I tried to fire it. The trigger was very heavy feeling when I dry fired (with a snap cap). When I did get to fire it I couldn't hit my 4" spinner target at about 15 yards. I coudln't tell if it ws the sights or the heavy trigger causing me to be erratic with my firing. I decided that this pistol was not for me. The next day my wife spoke with one of the distributors we buy guns from, who asked her if I lubricated the main spring. I normally don't go through the process of taking the MSH off to have access to oil the main spring. LAst night I took the time to remove the MSH and oiled the plunger that rests on top of the main spring. After assembling the pistol the trigger was noteceably lighter. So I went a little farther and put some oil on the sear and hammer connection. Once again it felt noticeably smoother. I use TW25-B grease on the rails and at the barrel bushing, and I use BreakFree CLP on the other metal to metal contact areas. I usually have a fairly "wet" pistol at least until I have 400 or more rounds through it. Admittedly I know just enough about pistols and 1911's in particular to be very dangerous. Is there any other routine maintenance or lubrication that I should be doing?
