No modification needed. This is a highly Polished Ghost Marine 3.5 angled connector that will feel smoother and lighter then your stock trigger feel. Cleaner break with nicer reset. Self-cleaning channel. This connector would compare to an Ultimate 3.5 with a slightly higher polish. 

This 3.5 LB Trigger connector is humble homage to US MARINES past and present. To friends and family who are Marines, this is a piece of American Cold Steel that will transform your Austrian Pistol into a loyal straight shooting MARINE. Semper Fidelis!
