This is kind of my question. Is it a non issue, or will it cause a problem later on down the road and need to be addressed now?
Were the pins somewhat tight when you installed them?
Can the pins be easily pushed out or is there some effort required?
If the answer is Yes and No. Then you should be just fine.
by tight do you mean did they have friction fitting to the pin holes when just inserting the pins without any FCG parts in the lower? Then no. I’ve never had a lower where the axis pins don’t literally slip through like a greased pig (although these LaRue pins seemed to be easier fitting than my BCM or even PSA FCG pins I had lying around). My colt included. When inserting the pins in with FCG parts in place, sure they had to be lightly tapped in due to the friction of the disconnector or the hammer creating some tension, and it was a tight enough fit with the parts in place. I haven’t noticed any walking
and for the second. They require a little bit of force to jump the J-spring or the hammer spring legs. Not as much as my mil-spec triggers (I noticed that even the MBTs that fit like a glove with a nice tight fit in the hole and no wiggle required less force than any mil-spec style trigger. I still have to take the end of a plastic punch and give it a push, but on my mil-spec single stages it requires about double the force.) But it’s not like I can push them out with my numb nail or something. It’s just that I can pop them out of the hammer legs with a punch and a good solid “push” while my mil-spec triggers require me to push hard (this is all done with the hammer dropped, as with the hammer cocked jumping the legs is nigh impossible without using a a hammer tap and I didn’t want to do that)
EDIT: Just out of curiosity I took one of the “loose” lowers and reinstalled a basic PSA EPT trigger I had taken out of a gun a while back and it also required more force to pop the trigger pin out of the hammer spring legs than even the “perfectly fit” Larue. Must be something about the LaRue itself then in regards to that. (also, no pin movement in the holes with the EPT trigger installed either, even when showing that movement with the MBT with the same pins)
Wouldn’t you think some of the difference in force required to remove the pin is because the MBT disconnector isn’t held by the trigger pin?
Ooooooooo. Durrrrrr. Good point. Actually I’d bet you $100 that’s exactly what it is. I feel like a moron
slight update. Geissele G2S trigger installed. Same thing. Although 26 Inf’s inference about the pinned disconnector being the reason for the extra force on the mil-spec trigger is 99.99999999% right. since the G2S disconnector is being held in by the trigger pin it requires just as much force as the mil-specs. Makes perfect sense.
with that being said, it seems to be a mixture of two things. One, the two stage triggers interact slightly differently with how much “slop” is perceived in the trigger pin holes. Put a mil-spec trigger in with the Geissele pins and the visual movement stops. Put the MBT or the G2S in with the exact same pins and I see that wonky little slight movement on the takeup stage.
2nd, it’s probably the pin holes being just so slightly off in comparison to others. Annoying, but as Iraqgunz said, it locks in tightly and took some work to get the pins in, so not much I can do about it. Only option is to live with it or get some oversize .155 pins instead of the normal .154…killing my OCD as I’m used to NO MOVEMENT with gun parts, but as long as it functions and isn’t going to damage the pins or receiver I can live with it.
(although I gotta say. I way prefer the MBT over the G2S… I got really used to the wider trigger shoe and it breaks nearly a full 1 lb lighter than the G2S and I kinda prefer the “glass rod” feeling of the MBT vs. the “carrot” of the G2S. I’ll have to see how I like the G2S-E I got)
only reason I even brought it up was that over at Calguns they were mentioning that lateral trigger/hammer pin play forward and back or up and down would cause exponential egging of the trigger holes and that the fix was a super tight fit of the pins to the hole walls
