With both of mine back in Sigs hands for warranty work it is extremely painful. Wowsers! Details please???? First I love the damn things. Both of them have lead and copper inside the piston. It looks like the gas port/hole was drilled in a bad spot and should have been chamfered or something. Small amounts of lead and copper are getting shaved off and forced into the piston. Called Sig and they sent out call tags for them. I still have not heard back yet, its only been a little over a week since they got them. |

I'll make sure to look for that in mine - I like how it shoots, but am very disappointed with how dirty it gets, and SIG's backpedaling on the trigger compatibility, and the charging handle, and the magazine situation. |

All I did for the charging handle was file an angle on the straight surface that keeps getting abraded. I've seen the paperclip fix and I didn't want to throw office products into my receiver. Weapons are mentioned to be used so a little filing and alumablack took care of that issue. |

View Quote Sorry, I meant the "ambidextrous" CH which wasn't - I've probably not charged mine enough to experience the abrasion yet. Kinda hoped SIG would have a fix by now though |

I've been using a SD-C with no issues. I presume Sig is just concerned that preemptive trigger wear will occur on lower quality aftermarket triggers without the blocking mechanism the stock trigger has. |

View Quote Interesting on the CH - is that a Gen2 upper? I understand AR triggers *work* fine, but the issue is SIG's effectively supporting them and then explicitly NOT supporting them. Would be nice if SIG would retrofit the advertised ambidextrous CH to the guns shipped w/o them. |

They probably did extensive testing on their triggers to maximize reliability. If someone goes and buys a crap trigger and the gun breaks it or it causes a dangerous situation, it shouldn't be on Sig. I wouldn't expect them to warranty the trigger on my MPX any more than my MCX. If my trigger breaks I'd expect to call Geissele for support. If you're having an issue that isn't trigger related and need to send it in, just put the stock pack back in. |

Okay maybe a dumb question but searched the last several pages and couldn't find it. The question is on thread pitch... All I can find is that it is the 13.5×1 LH is standard. That being said, a dealer had one in .5 x 28 and he said the new ones are all coming that way. Can anyone verify this, or is this just a sales guy blowing smoke?

The only guns coming in .5x28 are MCXs. I'm sure coregon will be able to chime in though with a slightly more informed answer than myself. |

Anyone else experiencing a loose carrier key? Some play between the carrier body and key has become apparent after about 550 rounds.

Anyone else experiencing a loose carrier key? Some play between the carrier body and key has become apparent after about 550 rounds. Mine is lose. I believe it's normal. Thanks for your input. I just got finished looking at my carrier in more detail, and I'm a little less concerned. I had assumed there was an interference fit between carrier and key, but I just discovered that the key is user-removable, and it's just being held on by a spring-loaded detent. It appears that a super tight fit between the two was not intended and, if that's the case, some small amount of play would probably be normal. |

There are KeyMod MPX-P's and MPX-C's (16" barrel with collapsing stock) showing up GunBroker.
http://www.gunbroker.com/Auction/ViewItem.aspx?Item=521875149 More importantly, these guns are being advertised as Gen2 uppers with larger ejection ports to accommodate 40SW and 357Sig caliber conversions. Can anyone with ties to Sig confirm if these are indeed Gen2 guns. I was under the impression that the MPX-K would be the first Gen2 version to be released. |

This is a copy of the email I received from the merchant who is selling the KeyMod MPX:
"...we just attended SIG's new product training and purchased these directly from them on Tuesday. We are the foremost MPX aftermarket supplier and gunsmith and are very familiar with the line. SIG specified that the Gen 2 are the Keymod, grooved top picatinny rails, larger ejection port, longer bolt carrier, and different barrel extension. We have confirmed in house as they barrels do not swap with the newer gen and the ejection ports are physically bigger. The part number on this pistol is SIGMPXP9KM MPX P 9MM 8". You can call SIG to confirm." |
|
Will the keymod rails fit the gen 1's
Also will we be able to get replacment 9mm barrels in other lengths for the gen 1's |
|
Guys - as mentioned in earlier posts, the keypad MPX guns are "Gen2". They can also be identified by the scalloped top picatinny rail.
|
|
Has anybody confirmed that Gen 2 uppers fit original lowers? This was stated by Sig some time ago but have not heard anything since then.
