I shoot 400 rounds a month minimum with guns I consider broken in. In a month where I get a new gun that number could go up to 600-800 rds that month. In one weekend with my new P30 I put 500 rounds through it. That's just two days.
There's no accessory as valuable as trigger time.
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
