Which loud suppressor for 45ACP?

This is a branch off a previous thread, which had good suggestions:

However, the focus is narrower this time. What would be a good suppressor that is as small as practical for shooting without ear protection indoors? Must use no wipes for ease of maintenance. Also, it's better if it allows to use the original sights. The distance between the bore axis and the sight line is 14.5 mm on the gun in question.

I love my Osprey, light, fairly quiet low maintenance and can still use low profile sights. Mounted on an FNP45

Osprey was MachIVshooter's suggestion as well. If only it were a little shorter. Or, twice shorter.

Unfortunately, it may be that my request parameters are impossible to satisfy. Osprey is already rated at 131+ dB in the .45 ACP version ("at the muzzle"), even with the length.

You painted yourself in a corner with what you want/need it to do.

Grab an Osprey and call it good.

SilencerCo makes an Osprey 45K as well... 1.5" shorter, 3 oz lighter, and 6 decibels louder than the regular Osprey.

I do like my full size Osprey though.

Osprey is one of the quietest, but it's not 131. First round comes in about 138-139, then it will drop to about 133 by the 5th or 6th. Most other 8-8.5" cans are right in that 133-135 range with .45 ACP. It's just a big dang hole, hard to slow and trap gasses & quench flames. Shorten them up, it gets even louder. My 7" Phoenix is 138 dry, 129 wet.

Getting a 4"-5" .45 can that will not interfere with your sights and be hearing safe without wipes is squarely in the hollywierd/fantasy zone. I've built some very compact ones, and while they definitely take the edge off, they're well over 140 dB.
