I have found a slightly used (less than 50 rds.) P3AT for sale for a decent price and would like some opinions. What should I look at or check before I fork over the cash? Any signs of a problem that might be visible that I should look for first? The guy says it is in like new condition and has never had a hiccup, from the pictures he has sent me it appears to be in like new condition. I just wanted to know if there might be any early warning signs to look for. Thanks in advance.
