hi! Im new here. I bought 8rnds 40cal mecgar 1911 mags for my para pro comp 40. I tried my friends ammo for thier 2011 and it wouldnt fit. But factory ammo runs great but shooting factory ammo is so expensive. I going with 40cal reloads. What loads or OAL of the ammo would you suggest? I would like to shoot in IPSC classic div. Please help.
