For those unfamiliar with the HERA ARMS TRIARII you can watch these videos:
Given the demand received from several followers that is or is not possible to use a silencer on TRIARII i decided to post the answer in detail . . .
Assuming that the company does not certify the TRIARII for use with silencers now we analyze the reasons (for the Glock model):
1 – Length
The length of 15,6 cm / 6,14 inch from the muzzle of the Glock to the muzzle of the TRIARII is the major problem …
The dart stuck in the barrel makes it clear idea of the problem because with the slide locked open the dart touches even the TRIARII… So a silencer block the firing cycle makes it impossible to the proper functioning of the gun; perhaps it would be possible to shoot (as long as the silencer fit) but the weapon would jam…
2 – Cocking Handle
Another problem is the cocking handle of TRIARII (unlike the CAA RONI) is on the front of the Slide making it impossible to screw a silencer.
It would be possible to mount only having a longer barrel of at least 5 cm / 2 inch than normal but, in any case, it will go back to the problem described in point 1

3 – The dimensions are not enough to use a silencer:
For example, the Ti-RANT 9mm™ Pistol Silencer (AAC) which has a diameter of 1.38” is unusable
concluding:
No you can not use it with a silencer (perhaps it is by installing a custom +- 12 inch barrel)

very interesting … thanks !
What if you dropped in a longer barrel (threaded) from Lone Wolf and then the length would get you past end of the Triarri. It would add some length but maybe worth a try.
could be a solution
but it would take a very long barrel as I wrote..
How about 9″? they will even thread it for you.

i want, got it for the g22
If someone tries it with a custom barrel let me know
the Design needs a simple modification by Hera, the cocking lever retainer and spring is part of the main reason the fron cannot be enlarged for a silencer, there really is no reason for the coking lever to have the spring if they adapted a ball catch like the FAL. this would free up the front to be widened to take a silencer. Anbody know a machinist?
After watching these videos, I am wondering if the HERA ARMS TRIARII CONVERSIÓN KIT will work for a SD9VE S&W 9mm pistol.
And if it works, how can a I purchase this kit and what is the price ?
How much is this roni kit? And how to order?
The 10″ barrel of several manufacturers should be enough to use a silencer.
