All, I recently picked up a NIB Delta Elite. Having never owned a 10mm 1911, I am wondering, what is the spring replacement schedule for the pistol? Is it the same as a full size 1911 5000 rounds and change all? Is it more like a commander or compact and change the recoil spring at every 2,000 and change the rest at every 5,000? Is the factory spring sufficient for full power 10mm loads, ex. 180grs. @1300fps? If not, what spring weight do you recommend? Thanks for the help!
