New 6920 is shooting 2 round bursts...

[Dave L.]

I'm sure it's my fault;
I installed a KNS precision gen 2 hammer/trigger pin kit on my new 6920.
I noticed the trigger pin was a hair wider than the receiver- so it's somewhat loose there but not much.
If I pulled the trigger and immediately released the trigger it fired a 2 round burst, if I pulled the trigger and held it in it would fire 1 round, but when I released the trigger for the reset it would fire a 2 round burst.:confused:
Any one have the answer before I hand it to a smith?
I was using Blackhills 55gr. FMJ/Pmags.

Did you buy the correct .170-173" pins sized KNS pins or the smaller .154-.155" size. Using the smaller size would cause doubling or worse.

I recommend putting the stock pins back in until you get the correct set.

Yup- I just noticed that I had the wrong pins...I swore I ordered the bigger ones.
Put the factory pins back in for now. I knew I installed everything correctly- so I was a little surprised tonight.
Thanks Robb, I figured you would chime in.
Take care,
Dave
