not bad.......I have this obsession with 400.............it's like my "buy price"..............bought MANY guns for 400....most recently I picked up the same gun as you a LNIB G23 night sights less than 200rds fired, a G19 same thing, and a Sig p229......each were $400................
I consider ANYTHING under $450 for a good quality handgun a good buy so good job.............I see a LOT of G23's go up for sale....I don't know why...I just assume people realize they don't care for the .40....but who knows
enjoy the new toy....
