Hello all. I picked up my new PS-AT yesterday and purchased 200 rounds of magtech ammo and spear gold dot jhp to break in the gun. One hour and 250 rounds later I had a pretty bloody right thumb from slide bite, tired hands and more failures to feed than any gun I have ever shot. I kept saying to myself, "This is ok - this is to be expected - I am breaking it in - it'll get better." But it didn't. I am experienced with pistols - used a very solid push/pull foundation, kept a tight grip and still had these issues. I will go back next week and see if the situation improves. Any suggestions, including proper lubrication information would be appreciated. (I primarily shoot .40 & .45 Glocks which require very little gun oil - so I am curious about what you folks do in that regard. Thanks.
