Got a line on a used kimber custom ll for 550.  Very good looking. What do you think it's worth

Pics, any mods?

Custom II is kind of run of the mill Kimber nothing special.  For $550 that is a good bit down on a Springfield.  I own a Stainless Target II and a Grand Raptor II along with a SA Loaded and SA TRP.  My Kimbers I have modified them a bit (removed schwartz safety, swapped in GI guide rods, changed plastic MSH to a steel one, and did some trigger work on the Target model.)  They are ok pistols for a production gun but a few things do bother me about them.  When you pay that much for a pistol a steel MSH is not much to ask for and a better warranty.
