I have some WWB 147 somewhere and a few cases of Winchester USA 124gr FMJ enroute.

Going to look for some gen1 mags on sale.

Debating a barrel chop to 5" and rethread instead of buying a metric piston.

I have no issues with FM's 147 reman in my AR9 (4" sbr) suppressed or unsuppressed. It also runs fine in my Glock 19, Beretta 92F, Ruger 1911 and HK VP9 (suppressed and unsuppressed)


Will Gen 1 mags run with 147 loaded to 1.169"? They FTF 115 loaded to 1.115" at a rate of about 1 every 20 rounds. I bought some Gen 1's on sale to piggyback the Gen 2 to 60 rounds.

You could try a Hiperfire trigger instead.

Already has a bridge as part of the design, and a better trigger pull to boot.

That's a good idea. I've been looking into them since you posted this. I would be interested in hearing from someone who has had over 4500 rounds through it to see if they had any issues as that seams to be where the decent aftermarket triggers start failing.

Update: I purchased the hiperfire 24c after I received an email from the company stating it will work with no issues.


I've got about 2000 with Hyperfire 24C. It's off the chain!!!


Thanks for the confirmation! I also called HiperFire on Friday and spoke with a knowledgeable guy (forgot his name) who said sig has been working with them and fully tested their 24c trigger and sig may start offering it as an upgrade in their mpx's. If this is true, it will be the first aftermarket trigger actually supported by sig!!

I've bought 3 sets so far (have them on AR's also). Run about $195.00. Trigger pull 2.5-3 with the springs for lightest setting. 24C comes with three sets of springs so you can select what weight you want.

I started with the Gen 2 mag and had trouble getting a round to chamber. The round wasn't being fully pushed out of the mag. I tried a Gen 1 mag and had the same problem with not being able to chamber a round. After messing with the mags and the gun for awhile, it started working. I attributed the problem with the strong new springs in the mags. I ended up running 220 rounds through the gun using both the Gen 2 mag and the Gen 1 mags. So, bottom line: the Gen 1 mags work fine in the Gen 2 gun. And, the MPX is a lot of fun.


Thank you for this. I hope I can save a lot of $$ buying gen 1 mags when I can find them.

Greetings, i had the same problem with a gen 2 mpx inpurxhased last year with gen 2 mags. I recently purchased another gen 2 mpx with gen 2 mags and it has run fine out of the box. The springs in the mags do put a lot of tension on the rounds which in turn but tension on the bcg. Leave your mags loaded to capacity for at least a week. This should clear up the problems. I read on here that some people use a wooden dowel or kitchen spoon to cycle the empty mags. I found this does not work as i cycled my mags at least 50 times each and still experienced malfunctions. Its after leaving them loaded for over a week that my gun cycled flawlessly. I believe the gun likes to be run wet with a thinner lube. I have no experience with gen 1 mags.
