John, You may need to use high velocity ammo, at least 1300 fps, at least until it is broken in. (Your owners manual recommends 1 1/8 oz 1290 fps or greater for break in) Some guns are finicky and work better with some brands than others. After break in, your manual says 1 oz loads of at least 1290 fps.

John, does it do the same with full power hi brass loads? If so, first thing to do is to disassemble and clean even though New. How to video here : youtube.com/watch?v=_XgO9_4Fx54 ----- If this does not resolve the issue, contact EAA/Girsan for warranty repair. https://eaacorp.com/repair-warranty/
