It just plain works... with any primers.. take it out of the box and use it... its thats simple

installed them this evening.. work perfectly

Will do, as soon as they get here

I agree

The barrels and comps are from Carver Customs.. They both run great and flat at major power factor, but they aren't like a steel frame 2011

yes... in the ones with the comps

Anybody else who has installed an aftermarket trigger have issues with the trigger pins coming loose ? I currently reinstalled my factory trigger pins in my Tooth and Nail trigger and it seems to be holding tight. But i just ordered these from Hayes. http://hayescustomguns.com/vr80-anti-walk-hammer-and-trigger-pin-kit/

This is who I use.. https://www.carvercustom.com/ecommerce/m-p-accessories.cfm

You wont be dissapointed.. it just plain works

i also agree, most SIG issues are from owners users trying to run too light of loads or messing with the springs. I also have 15k plus rounds through mine with zero issues.. What you should do is go to a match try a SIg MPX and JP and decide for yourself.. There is a night and day difference between the two.. The Sig MPX i can only describe is like shooting a M&P 15/22..

My gen2 sig MPX is all factory with the exception of a handguard. Keep the gas system clean and the bolt oiled, you will be fine. I also had a built QC10 with all the bad a$$ stuff and it ran great, but nothing is as soft shooting as the sig MPX

The PAL filler just plain works.. no questions.. take it out of the box and use it..

thanks for the info..
