Little clarification - the PSAIT trigger is curved, adjustable only for more than-journey and has not been issued to the SAO Legions (though I can’t discuss for The brand new 10mm SAO Legion). If this was my pistol, I’d take a Dremel and hand file to your opening to widen https://gunsandammunation.com/shop/sig-sauer-p220-legion-semi-automatic-pistol/
