Just a heads up, seems they are shipping these with a grease... some say it's cosmoline.... haven't seen it myself. Either way, they are doing this with the P320 X5s and guys are running to the range and letting er rip with issues. They then them up and lube them and they eat everything like candy. I clean and lube every gun I buy but I guess some don't.
Agree 100%, whether it's new or used. I field strip, clean/inspect and lube as appropriate every time before taking a new gun to the range. This lets me make sure the gun was assembled correctly and also lets me function test the gun before a live round gets fired. A good visual and mechanical inspection can also help you make sure its not going to go kaboom in your hand.
