Congrats on your new 9mm 24/7 Pro's!!! I love my Blued 9mm 24/7 Pro and I've no doubt you'll love yours!
Should be no trouble with your ammunition! 24/7's are very feed reliable! Mine has fed and fired everything!
Before you head to the Range, give each Pistol a thorough cleaning and Lubing! The packing grease in the guns is not considered a lubricant and will just attract powder residue, gunking up the gun.
