Also for those that said it wasn't a good round to break in a gun with, what is a good break in round?
Something hotter and heavier (bullet weight). Try some 147 gr ammo or some 124 gr NATO. Will break in the recoil spring faster.
Know the status of your weapon
Keep your muzzle oriented so that no one will be hurt if the firearm discharges
Keep your finger off the trigger until you have an adequate sight picture
Maintain situational awareness
