A guy that I shoot IDPA with has a 4" for sale. It has night sights on it with the originals included and several (4-6)10 rd mags which is fine if I'm idpa'in with it. It has been finished with np3 from Robar and he'll throw in a probably illegal comp-tac holster, which is also fine because I'll probably just shoot local matches with it and get a kydex iwb if I ever decide to carry it. Also will need a pistol for my oldest daughter in a couple of years. Don't know anything about the gun other than he bought it for idpa and decided on a sti 9mm for esp class. He's asking $550. Q's Does that sound reasonable and will the finish void the warranty or do you think this is a custom shop deal. Any info would be appreciated. I'll see him at a shoot thurs and get more info.
