I've owned a stainless Springfield Champion, a "Loaded" model, for about eight years now. It's served me well and is still one of my primary CCW/HD handguns.
I used it for the 5-day Defensive Pistol I course at the Chapman Academy in 2002. During those 5 days I went through 2300 rds. of CCI Blazer ball ammo. The pistol was only cleaned after every day's class ended, though I did put a drop of oil on each rail and the barrel hood if it started to get a bit sluggish towards the end of the day.
Other than one FTF due to a defective round, the only malfs were those set up for Immediate Action and clearance drills.
Since then it's gone through several thousand more rounds of assorted commercial and reloaded ammo. It's only required two routine spring changes and nothing has broken.
$900 though? Is that the MSRP, or the retail a dealer has quoted you?
If it's the MSRP, you should be able to find one for substantially less with some shopping around, IMO. I know it's been a while, but I paid about $630 for mine, stainless steel, ramped "bull" barrel, ambi thumb safety, Novak-style tritium sights and all.
