How heavy does a suppressor need to be to require a booster?

[friendlysniper]

The suppressor I am building is going to weigh about 12 ounces when it is finished. Is this light enough to not require a recoil booster?

The barrel length of the handgun is 4 inches, and its a tilting barrel, short recoil operated handgun (smith and wesson M&P 9c).

I don't think there is a set weight, even for the same model firearm as each one may be different enough to
have some require a booster while a few may function just fine without. Ammo impacts the equation as well.

The general rule of thumb is sub-sonic ammo out of a tilting barrel design is probably going to need a booster
of some type to operate correctly/cycle.

Try without, if it works, you're golden. If it doesn't, get a booster.

Its not only about the weight but how its distributed and the impulse of the bullet powder combination upon the suppressor.You have leverage effects and harmonics,resistance plus length factors.I think you will need a booster if you are doing the maglight can described elsewhere.

I made a 9 mm can that is only 6.4 ounces. In order for my Browning HP to function correctly with 147 grain subsonic I had to use a hot load (1060 fps) and cut down the already very light weight spring (8 pounds) almost an inch. This left the spring with barely enough tension to chamber a round. I had to check all of my ammo carefully to ensure it chambered easily.

It worked fine for 200 rounds but then raised ridges on the barrel locking lugs. I have photos of the damaged barrel elsewhere on the forum. The can is only used on my 22lr rifles and a 1895 Nagant revolver now. Eleven years ago it compared okay with an AAC can, now it sucks in comparison to the new models. Make or buy a recoil booster and do it right.
