Newb question here. How do I tell if my trigger assembly/lower is a large pin or small pin group. Wanting to buy a nice trigger group but not sure what my specs are, looking for some help, some pictures or a link to something on this site would help. Thanks.

Who made your lower? If it's not Colt you want the small pins.
