I’ve never loaded for a LeadStar PCC. I’ve loaded and shot through some of the other brands and the MPX. My best experiences for loading for PCC is N320 with 124/5gr bullets. Blue Bullets in 125gr or Precision Delta 124gr JHP both work well. I practice with Blues and load PD’s for matches.

Anyone taken the MPX PCC factory muzzle brake and drilled popple holes in the top? Just a thought i’ve been having and wondered if anyone has done it and noticed any difference. Thanks for any input

If you want it to run out of the box my vote is JP. I came from the AR Platform to the Sig MPX and still question my choice of changing. The MPX by far is a softer felt recoil but i’ve had the typical MPX extraction and feeding issues. I think with the MPX they’re hit or miss on reliability. Buy the JP and forget about it imo....

Same here...

MBX make a compensator in the 13.5x1lh thread pitch or was the PCC barrel rethreaded?

I prefer muzzle down myself and only because I have a Rugged Gear cart that tame the rifle muzzle down. A PCC with a chamber flag is the same as a holstered pistol in my opinion.

I went with the CompTac pouches. I’m yet to have a mag fall out with 40rds loaded and turned horizontal on the belt. Gen2 mag with TTI +11 downloaded one to 40.

I’ve been researching and debating a spare parts purchase for my MPX. I’ve seen quite a few people talking about firing pin failures. After disassembly of mine I found that my Gen 2 has the firing pin with no spring in it. Apparently Sig is replacing this style bolt with a newer version with firing pin spring. My question is have any of you contacted Sig and requested the upgrade without having a broken firing pin? I like to be prepared with extra parts and apparently buying a extra firing pin for this style bolt is not an option. Just trying to think ahead of the 2019 shooting season. Coming from a AR9 i’ve experienced the broken firing pin on the 1st stage of a Lvl2 match and not having a spare. Thanks for any input you might have.

Thanks much for the input!

Anyway to tell the Gen 2’s apart aside from calling Sig? Mine has the 3prong tuning fork style flash hider on it. I’ve noticed thats different from two other friends Gen 2. MPX like faster or slower burning powders when reloading?

Anyone changed the flash hider on a MPX Carbine and notice a difference? Not sure if you could make them shoot much softer but was just wondering out of curiosity. Thanks for your input

New to the MPX and looking to buy a couple mags pouches. What’s everyone using for MPX Mag Pouches?

Mine came in the mail today. At first glance fit and finish is great!! I’m sure its as good as my other TF basepads and will work great!

Funny you say that as I ordered my HMR Pro yesterday! Be here next week!

Care to shed some light now that youve had the rifle for some time?? Ever get into that BMP??
