Was considering replacing a broken trigger pin with the KNS gen 2 set. The ones with anti walk retainers.
But was thinking that if they broke, I’d have to have another threaded KNS pin and wrenches in the field to repair. Though I could just drop in a stocker in a pinch.
Are they a good idea? Have they been known to break? Is it a solution looking for a problem? Thanks.
I want to an armorer class a few years ago and these were discussed and were highly thought of within the class. I really like them and install them in my rifles.
Window dressing.
While I have them on 2 of my rifles, I must admit that they’re not really a must have item.
A properly built lower with standard milspec triggerpins should hold up just as fine. If you’re tight on $ you’d be better of spending them on other items that you need more.
That being said, if you can afford the $, they’ll surely ease your mind if your afraid of the pins walking out. So I guess they’re more like nice to have.
I used to have a set installed. The general consensus is that they don’t really do much for most, if not all, users. The provide a nice place to rest your finger though.

Hey, they give me +2 internetninja coolness in “show your rifle”- threads 
The trigger pin is a relatively low stress part. That means your other was either detective or low quality. Don’t waste money on KNS crap spend it in something important.
Get a Geissele trigger, they come with their own trigger pins. 
KNS is not needed by most users, IMO.
I think they’re a waste of money.
I either use stock Colt triggers or Geissele SSAs.
Neither Colt nor Geissele recommend KNS pins.
You need the pins anyway, if the factory ones you have are doing the job…then press on. If you are doing a ground-up build…whats the harm in using KNS? I put them in my SBR’s, just because.
Just a pretty part

My dad has a Colt hbar from 93 that has had close to 10k through it and now his factory pins are walking out petty consistently. We have ordered some kns pins to try and help the problem. But for most rifles it is not needed.
Some of the well shot out Colt SMG’s I’ve seen lately with working or broken trigger pins could use them. Are they overkill for 99.9% of shooters and applications? Probably. I’ve put them on a couple of builds to check them out.
I have them on mine holding my sweet Geissele trigger. I knew I didn’t need them when I put them on. I just liked the look. Yeah, I’m that guy.
A. Did you replace the hammer? The “J” spring inside the hammer holds it in place.
B. Did you replace the hammer spring since it holds the trigger spring in place?
With a bit of a metalworking/machining background I’ve always been able to see at least somewhat of a benefit, as steel does wear aluminum. Exactly how much wear is debateable. On a similar note, even Bill Geisselle himself mentionsin one of his install videos, that his pins are apparently highly polished/ground/etc (forgot exact adjectives he used), but the point being, Geisselle himself at least claims to address steel pin vs aluminum receiver wear issue himself.

B: yes, A: no. I will give this a try and see if this fixes it.
Thanks IG, your insight is appreciated.
Tried the kns pins but switched to the geiselle pins, which are available for purchase separate from the trigger/hammer sets. Much prefer the G pins; slightly larger diameter than kns and steel is harder and polished, less likely to create a burr that will eat up the lower receiver hole. Cheaper as well, and no Allen wrenches needed if you want to take apart fcg.

That is stupid. You replaced some of the best pins made with a gimmick designed to remove money from wallets. Geiselle specifically states not to use kns pins with there triggers. Your trigger more than likely Will be better if you put in the Geiselle pins. The kns pins are the wrong size and can cause many problems.
Google Geiselle and kns pins, and select the link to adco. They explain it in detail.
