I'm still learning, but the I know that Browning actions require a piston/LID. Rifles are fine with a fixed mount. My MPX works great with the LID. I could spend $75 for a fixed mount to go with the 13.1 LH, but if it ain't broke...Ok. I thought you were supposed to use the fixed mounts with the MPX. My dad is always yelling at me to make sure I don't use the spring on his Gemtech Tundra when shooting his MPX or 9mm AR and making sure I put the spring back in when switching to handguns.
Thanks for the research. I guess I'll get a 13.1 LH fixed adapter. Range report to follow!I think it's going to hurt in the long run.
From Gemtech's website:
L.I.D. is an acronym for Gemtech's Linear Inertial Decoupler. Many suppressor manufacturers offer a similar device marketed under different names. They are also sometimes referred to as a Nielsen device. This is a bit of a misnomer as the LID operates differently than a true Nielsen device.
The LID is used on handguns with a Browning-type action (Glock, HK, Sig, etc.) where the barrel must tip to unlock from the slide an cycle. These types of pistols are sensitive to additional weight on the end of the barrel (such as a suppressor) and must lift this additional weight to unlock the slide. The LID allows the weight of the suppressor to temporarily jump off the end of the barrel while the barrel unlocks, and then provides a small recoil impulse to assist the gun in cycling and loading the next round.

If you are suppressing a Glock, HK*, S&W M&P, Sig, or Springfield XD handgun you will need an LID in your suppressor. Depending on the size and weight of the suppressor you may also need an LID for use on the Beretta M9/92FS. For other applications please contact Gemtech and we will let you know if you need the LID or not.
LID's should not be used for pistols with a fixed barrel such as the *HK P7, or on carbines with fixed barrels. This can damage the LID and suppressor.
The MPX is a fixed barrel, isn't it?
I would call Gemtech and ask them about the MPX with your suppressor. My dad's Tundra came with the spring and a fixed spacer. When he chopped his MPX barrel he had it redone in 1/2 x 28.
I don't have a MPX, but I use the Hybrid on a 300blk MCX and 9mm pistols. Its insane how quite this thing is. Even at indoor ranges people come up and ask me ... 'what the [email protected]#$ are you shooting? The only way I know you were shooting was from the smoke.'CALIBER
