Lighter pistol so recoil is stout because of it. OK DA type trigger.Go to KTOG and read up on lube and do the fluff and buff. Add a couple pieces of bike inner tube to the grip to help hold on to it. Now bang away. It is a light weight defence pistol not a range gun. Take turns getting rounds down range while proffing the pistol. If you have problems ,change ammo, still problems , change shooters. KT is one of the best CS to deal with also with any issues your dad might have.
