Better choices don’t waist your money imo - JE Machine Tech Skeletonized Advanced Operater Oversized Trigger Guard

Does not have the wider sides of most guards that fit flush to outside of the receiver. The front connector is a one sided spring loaded pin. The rear is a roll pin. Most of the extra space is directly below the trigger if straight shoe is used not to the front lower portion where it is most needed. If you have a curved trigger it gives a lot of room for gloved finger
