I have a chance to pick up a LNIB P226 from a friend; it belonged to his father-in-law who recently passed. He says it looks new and was purchased new by his deceased father-in-law 15-20 years ago. Is there anything to look out for or stay away from? The first few digits of the serial number are U519XXX. They seem to go for around $550 or so on gunbroker. Going to check it out later today. Any advice is appreciated. Thanks.
