Sig MPX generations

[Tampa-XD45]

What's the deal with Sig MPX generation numbers?  I've seen references to gen 1,2 & 3 on this forum, and yet this response from the rep at Sig states there are only gens 1 & 2.

 

Thank you for contacting Sig Sauer.

 

There are only two generations of the MPX. Generation 1 MPX were introduced in 2014. In 2015 we introduced the Generation 2 and all models onward are Generation 2.

 

I hope this helps.

Yes, the rep is correct. There are only two generations of the MPX.

 

The last iteration is not a gen 3. It’s officially called the MPX PCC Competition model. It has the full 16” barrel with the muzzle brake which can be removed and replaced with a different compensator or brake as deemed necessary by the user. It’s still a gen 2. However, majority of shooters instinctively call it gen 3 to easily differentiate it from the previous gens of the MPX.
