I used KNS pins on my first build before I had any knowledge and before I knew they were unnecessary and serve no practical purpose. They are pretty much like throwing $30 down the drain. I never messed around with uninstalling them because they were the updated version with the stronger pins so I knew they wouldn't hurt anything. On this first build, I used an ALG QMS trigger for reference.
Fast forward to last week. I was working on my 3rd build and decided to use another ALG QMS since I was happy with the first. I used the stock pins that came with it and everything functioned completely fine. What I noticed was that it had a little bit of creep. Just a tiny bit but it was still noticeable. I wouldn't have thought anything about it except that the first QMS I installed had absolutely no creep whatsoever. I decided to remove it and install it again just for good measure. I got the same results.
I then began to think if the KNS pins had anything to do with it or if I just got really lucky with the first trigger. I wanted to find out so I decided to use my $30 Amazon credit on some KNS pins.
I got around to installing them last night and to my surprise, the creep went away. It felt exactly like my first ALG trigger.
So here's the question. Was this just a coincidence or is there something technical going on? I'm not the slightest bit versed in all of the technical aspects but does removing the slight amount of movement in the trigger pin remove a slight bit of creep?
Just for the record, the reason why I use the word slight is because I tried the KNS pins out with a Mil-Spec trigger that was included in a DD parts kit and I didn't notice any reduction in creep. I'm assuming it's because the trigger that came in the DD LPK had too much creep to start with.
