I'm looking to switch out my Springfields titanium firing pin for a steel pin and more standard spring setup (for a better trigger pull), and so I think I'll change out the mainspring housing while I'm at it to take out their ILS lock system. But the problem I have now is this: my gun has a very black "parkerized" finish on it, and I'm not sure if buying any of the "blued" parts from ed brown, wilson, etc will match the gun. Does anyone have experience doing something like this? Would I have to buy parts and then refinish them myself to get the right color?
