Is it possible to fire 10mm through a .45 ACP suppressor without damaging the can, or are the pressures too high?

I suppose it or anything of this nature would be possible but...I have no technical data to support my opinion on this but, I think the pressure of a full house 10mm round would be too much for a .45 ACP rated can not to mention that I don't think it would be very quiet.

I've read that some .40 S&W can mfgs. don't recommend shooting 10mm thru their cans.

I'm sure someone will chime in that knows more about this than I do.

Well that would be strange since both rounds share the same SAAMI pressure ceiling levels.

Here is one link that states AAC will not warranty the Evo-40 with 10mm ammo.

There are other links included within that one that indicate people have done it but again, AAC will not warranty their Evo-40. I wouldn't do it with mine and take the chance of screwing up a $795.00 can.

Maybe this has changed?

Same pressure cielings, probably different volumes of powder in the case.

I was looking at ballistics and saw 185 grain bullets at 1450+FPS so it seems quite a bit different than 40S&W.

The volume is what overwhelms and destroys the can.

SAAMI pressure readings are related to the maximum peak chamber pressure. They bear no relationship to the volume or velocity of the propelling gas. The .50 BMG cartridge does not have a terribly high chamber pressure, but there is one hell of a lot of gas associated with that cartridge.

We will not warrant our .40 caliber pistol suppressors for the 10mm. However, we do warrant our .40 caliber submachine gun suppressor for use with the 10mm. Dedicated subgun suppressors are built differently than pistol suppressors.

What about the original question: how would firing 10mm through a .45 ACP suppressor affect its durability/service life/warranty?

I would expect it to be destroyed.

The 10mm is pretty powerful.

If you used subsonic 10mm loads, it should be OK, but supersonic 10mm is nearly as powerful as a .44magnum.

It's a suck-ass round for silencers in its std velocity form, because it combines a large bore bullet, with a lot of gas volume, and supersonic velocities.

Thanks for the reply. Then I won't buy that extended 6" barrel for my G20.

I have a box of factory subsonic 10mm but I can't see how it would be any different than a underpowered 45.

Or a normal .40SW load.

10mm full-power = YEEHAW!!
10mm subsonic = .40SW.

The 10mm came first, by several years. When the pussy FBI guys wanted downloaded 10mm ammo, after begging & pleading HK into making a USA-only 10mm variant of their MP5, S&W saw the light and decided to offer that same down-loaded level of performance in a 9mm sized pistol. And that's how the .40SW came into existence.

Not exactly:

The FBI's 10mm Pistol from the Law Enforcement Bulletin November 1989

Anyway, I do not put 10mm through a 45, but I am building a Glock 20 to put through a 40S&W can using FBI-Lite ammo (180gr@950fps).

anything is "possible"....now what is recommended is another thing.

To do this with absolute peace of mind I'd go with a quicksilver titanium suppressor. Don't think you'll have any problems then

Hmm, I may have to consider the same thing now...
