Not just the pins, certain shimano chains had major issues with the plates cracking around the pin. I don't think the problem still exists (At least I'd hope not), but it doesn't take much to create a reputation for failure.

How does one get off a KMC master link that wont budge? First time I've had this issue and I've used KMC for years.

I've had a SRAM 1070 break, and not on the power lock. Never a kmc. I still use both as I don't believe one failure proves anything. I've also had a couple of shimanos break, but that was years ago.

IIRC, it was the Shimano Ultegra 6700 chains that were getting cracked sideplates a couple years ago, and Shimano replaced that model with the 6701 to remedy the problem.
I had a friend have the same thing happen with a Wippermann stainless chain about 10 years ago.

I have never had issues with KMC chains under any kind of use from road cycling, mountain biking, or some rather extreme utilitarian use... just installed a new KMC chain on my commuter (8 speed) and locked the link up with my meager arm strength and then checked it after cranking on the pedals.

It's a dumb question, but are you sure that you have the right size Masterlink? I've battled with putting a 8spd MTB Link on an 11spd MTB Chain. It's difficult.

The modern chain ain' got that tube that the pin rides in and the roller rides on - surely y'all know that - indeed, the younger folk probably don't know that the modern chain does away with that extra part, on account o' they've never seen the olden day chain. The inner plate cleverly swedged to provide a bearing surface for the pin and roller - that were a smart idea.
Imo, the Whippy link is better, and so's the Whippy chain.

almost like new
OP, did you have any luck getting it connected?
As mentioned by several users, this is not a common occurrence with our Missing Links. Unfortunately, this has happened in the past with the Missing Links either receiving damage during shipping/receiving or debris in the pin seat resulting in an improper fit. Our apologies for any inconvenience/frustration this may have caused.
Also, as mentioned by several users, KMC does have a good rep. Many LBSs have an unfounded bias towards certain chain brands.
For removing your Missing Link without a tool, try this method. Just don't hit too hard! (originally posted by another user - thx): https://www.ctc.org.uk/file/member/201107050_0.pdf

FTR, most chain wear checkers are very inaccurate. Use a ruler for a more accurate measurement.

Chains....discussion is nearly always like a religious argument and as many wars have been started as a result.
I have seen a ton of Shimano and SRAM chains break. Almost always from incorrect installation.
KMC is the OEM for many other chains on the market including most/many of Shimano's chains.
KMC has changed the links to be interlocking instead of just simply slip together like before.
If you are having problems then you most likely didn't have the plates seated all the way before you tried to set them with pressure.
If you are having problems.....it's user error. Sorry.

I have the same experience as the OP. I have used several KMC chains in the past w/o any problem but the last one was a pita to put on. At first I thought maybe the missing link that came with the chain was defective so I took one from my stock. It was still a pita but I finally managed to get it on. After riding a while, it is now easier to connect/disconnect.

Took it to the lbs and they got it on. They also (both mechanics that is) said I made a poor choice of chains. They said I should stick with sram or shimano chains. Said the KMC will break under heavy watts. Actually he said wait til you're pedaling up that 22% grade to your house and it breaks, then you'll wish you had a better chain. anyone else have a KMC chain break while pedaling?

KMC the the best chain and they dominate the bike chain market with 70% market share. Those people have no business advising customers. Crooks.

You know, for $25 to $30 total you can purchase BOTH Open and Close tools from KMC. Beats the H+++ out of stomping on pedals...
