I was on 1 of my favorite places to shop and lo and behold I found something I just had to have! This is what most would think about when snuggling with their scary black weapon
Hmmm, never heard of these links before. I had to search online just to see what they are.
They are the external piece that attach to the hammer and trigger pins so they don't rotate, walk and/or fall out.
I was just reading about this. One article says for factory pins with the grooves they are supposed to rotate.
With the grooves the trigger and hammer springs hit against the groove to try and keep them in place. Most of the style pins I use are ss unlike the phosphate ones used. The 1 piece designed trigger groups sometimes doesn't lock in place as well as the 2 piece does. Both designs have benefits and withdraws.
