i ran into a cheap SD3G trigger for my build (PSA SBR) and ended up with a spare unused SSA-E trigger. i thought about installing the extra SSA-E into my Colt AR but the pins seem to be a little loose. i did a little research and found that a "large pin" set is made for the Colt ARs made before 2009.

my question is, will using a SSA-E trigger with smaller pins hinder the operation of the colt in any way as opposed to using the SSA-E with larger pins or is it just a matter of fitment?

will using a KNS anti walk kit help at all?
