Description
Metric left-hand threads can be a headache to find good muzzle devices for, which is exactly why this version of Griffin's Taper Mount Minimalist Flash Hider gets so much attention from MPX owners and folks running 13.5×1 LH barrels. It does two jobs at once: three flash-suppressing tines tame the muzzle signature when you're shooting unsuppressed, and the precision-machined taper gives you a rock-solid quick-attach point for Griffin taper mount silencers when you want to run quiet.
Why the Minimalist 9mm Taper Mount Earns Its Name
At 2.9 ounces, this mount weighs roughly 40% less than most competing suppressor mounts, and you feel that difference at the end of a barrel. Less weight out front keeps a pistol-caliber carbine or braced pistol lively in the hands instead of nose-heavy. The whole unit measures just 1.8 inches long with a 0.93 inch body diameter, so it stays trim on shorter barrels too. Griffin machines it from 17-4 PH stainless steel with a QPQ finish, and the tines carry integrated anti-resonance flutes so you don't get that annoying tuning-fork ping between shots.
Suppressor Compatibility for the TMMFH9MM1351LH
The taper interface works with Griffin's RECCE, Paladin, EXPLORR, Sportsman, and Bushwhacker series silencers, plus their Revolution and Resistance pistol cans when paired with the minimalist blast shield. It also supports the Optimus 9 in its mid-size configuration and the Optimus Micro with a taper extension. The tapered shoulder pulls the can into consistent lockup every time, which means minimal and repeatable point of impact shift when you swap the suppressor between hosts.
Installing the Griffin 13.5×1 LH Flash Hider
Setup is refreshingly simple since the design requires no timing. Thread it on, torque it down, and you're done, with no crush washers to fight or index marks to chase. Keep in mind shims are not included, so if your particular barrel setup calls for them, grab a shim kit when you order. Griffin also makes a Taper Mount Thread Protector that fits this device if you want to keep the taper surface pristine between suppressed range trips.

Frequently Asked Questions
Which suppressors work with the Griffin Taper Mount Minimalist Flash Hider?
It interfaces with Griffin's taper mount silencer lines, including the RECCE, Paladin, EXPLORR, Sportsman, and Bushwhacker series, as well as the Revolution and Resistance pistol cans when used with the minimalist blast shield. It also supports the Optimus 9 in mid-size configuration and the Optimus Micro with a taper extension. If you already own a Griffin taper mount can, this is a direct plug-and-play host mount.
Will the 13.5×1 LH version fit my SIG MPX?
Yes, the 13.5×1 LH thread pitch matches the factory MPX barrel, and owners regularly run this mount on that platform with solid lockup. It also fits other 9mm barrels cut with metric 13.5×1 left-hand threads, which are common on European-style pistols and PCCs. Just confirm your barrel's thread spec before ordering since Griffin makes this same device in 1/2×28 and 1/2×36 as well.
Does this flash hider require timing or shims to install?
No timing is required, which makes installation about as easy as it gets: thread it on and torque it down. Shims are not included in the package, so if your setup happens to need them for shoulder alignment, plan on picking up a shim kit separately. No crush washer is needed for this design.
How much does the TMMFH9MM1351LH weigh compared to other suppressor mounts?
It comes in at 2.9 ounces, which Griffin states is roughly 40% lighter than most competing flash hider suppressor mounts. That saved weight sits at the very end of your barrel, so the gun stays quicker-handling both with and without a can attached. The 17-4 PH stainless construction keeps it durable despite the trim profile.
