I realize caliber size and bullet weight alone will put the 10mm in the lead on this one. My question is which would be the "lesser" of the two evils if it had to be fired inside your home, do you think the 10mm would be as bad or worse than firing the 327magnum? The 10mm ( 165gr JHP) would come out of a full size 1911 & the 327 ( 75gr DPX) would come from a SP101 with a 3" barrel. I was just looking for some insight, I was debating the differences between the two for a " night stand" gun. I currently now use my 10mm, keep in mind I am NOT worried about over penatration more about the after effects of firing a weapon in my home and what it will do to my hearing... like I said any insight would be great

    I doubt that there is any practical difference between the two when it comes to damaging your hearing. Handgun calibers from .25ACP to .44 Mag produce muzzle blast on the order of 155 dB- the 10mm and .327 Magnum will both damage your hearing.

    10mm all the way! Not just because thats what I carry but between the two you do have more rounds if multiple BGs. My Delta is the go to gun for everything within 25 yards. Now if you can't handle the full power loads then yes you are better off with the 327 mag but if you can't handle it for the full 7 rounds find something else that you can be good with. Missing 7 or more times does you no good, so make sure you are comfortable with what ever you choose to bet your families life with.

    The average house has enough carpet and upholstery that the decibels won't be as bad as you might expect, granted it will be loud and I wouldn't do it on a regular basis. See pic below; a revolver will guide sound waves in a "more" direct pattern to your ears (via gas escaping out the sides of the cylinder to barrel gap) than a semi-auto (all gas forward). Will it make that much difference inside a house? I don't know, I haven't tested it. And I'm not going to. That said, lately I've been keeping a 2 inch barreled Dan Wesson revolver and a speed loader at bedside, though with 38Sp +Ps in it.

    That's a rough decision. But my opinion, if considering revolvers, stick with the classics. Get a .357mag and load it with .38s if you want something of a bit of a lighter load. Both are tried and true calibers.

    Carpet and upholstery will have no effect on the decibel level.

    Fired indoors, any handgun is going to hurt your ears... and is probably just as likely to damage your hearing. Don't sacrifice power for your hearing, as there's no point anyway.

    A Glock 20SF sits in my night stand with a mounted light. I strongly recommend the 10mm.

    Why would you use either of these rounds for home defense? Don't get me wrong, I'm sure they both have great terminal ballistics. However, consider their "post-terminal" ballistics. You are surely going to over-penetrate with either of these rounds.

    Any of the handgun calibers out there will penetrate beyond most walls in a house. So doesn't really matter. A 9mm, .40, .45, etc etc will penetrate 2 sets of walls.

    He generally likes heavier bullets. 10mm's are .40's that go much faster. Seems like a good deal to me.

    I am positively sure beyond a shadow of a doubt that you cannot shoot a 10mm as quickly and accurately as you can a 9mm so that is not an issue.

    I see your point, but if you put the round in the right place, don't need to. I have 155 grain pills doing about 1,360 FPS and my 180 grain over 1,200 FTS. You could be surprise how fast you can shoot a 10mm when trained. Accuracy first then work on speed.Been shooting one since early 90's.Very happy with the round. I also like the old but very good 45ACP.

    You're right, I stated that badly. It would absorb 'some' sound (stop it from reverberating) and not be as hard on your ears.
