G21 vs G17 for Home Defense in regards to SOUNDWAVES

Alright guys, I understand the pro's and con's to many of the popular handgun cartridges for home defense use. However, what I don't understand is how the calibers compare in regards to sound in a home defense environment.

What I mean by that is, I have a G21 and a G17 and I prefer the 17 for home defense for 2 reasons. First being it's capacity, second being it isn't nearly as loud as a .45.

I have read many posts where people are considering a .45 Glock for their home defense needs. Yet I never read that one of their concerns is that of how loud the gun is once fired.

I've fired my 21 outside, after the first shot my left ear is ringing. If I fire 2 mags, my left ear will ring for days. That is outside. If I fired it inside, the sound would be all most twice as loud.

It doesn't seem smart to have a firearm for home defense that will cause you to go deaf after firing it.

So, after all that ranting, am I missing something here or does this just simply not occur in most people's minds?

I think that will be the least of your concern if you need to fire on someone in your home. When the dogs start barking and I'm concerned about someone being in the back yard or something like that I always favor grabbing the 870 12 gauge.

A Glock 26 firing 147 grain rounds will be less loud than the 17 because it will be around 1000fps and therefore subsonic. The .45 is also subsonic but the larger diameter outweighs the difference of the sonic boom.

Well if you're shooting outside, I would definitely be wearing ear protection and I don't think it will matter much if you shoot a 9mm or .45 indoors because your ears are gonna ring anyway and like the other guy said, that's probably the least of your worries at that point...

I'm pretty sensitive to loud noises.
At the range I upgraded to 33db ultra ear muffs because the sound bothered me.

Unfortunately,
I've had the misfortune of having to fire a 40 S&W, in a small closed room, with no ear protection.

The weirdness was is wasn't loud at all.
No pain, no ringing - nothing.
Something about adrenaline I guess.

This whole thing about how loud your gun is in a house is highly overrated.
Use what you're proficient with and don't worry about that...

That's really interesting and a valid point. I didn't consider the effect of adrenaline.

Check out Lt. Col. Dave Grossman's book, 'On Combat'.

I don't agree with everything he writes, but it's a good book, full of data about that very subject, namely, altered senses during high-stress combat situations.

As far as shooting without hearing protection in other situations - keep it up and you definitely won't need to worry about, because you will lose your hearing, whether you're shooting a 9mm, .45, or .300 Win Mag.

I don't mean it as a concern but more along the lines of having all your senses intact as much as possible. I am not sure if firing a .45 vs a 9mm would be the difference in causing the average person to go def or not in a home defense situation. But if it is then wouldn't it be better to be able to hear your surroundings when you are in such a situation?

I wouldn’t go around testing what damage is done to my ears from the sound of firing a handgun, I’ll reserve that test for when it is a matter of temporary hearing loss or loss of life.

For ranges (in or outdoors) we use double ear protection. We have taken training that involved shooting from inside a vehicle, that was louder than I expected, even with ear protection.

I’m a bit more concerned about being able to stay in the fight after being shot and seeing my own blood flowing. No, I’m not going to practice that one either; although, we have practiced handling and firing a pistol under the assumption that either hand/arm is out of commission.

Like many have said, and from my own experience if your in a "oh S#!t" shooting you wont hear much of the shot, nor will you really recall how many times you fired the weapon.As for weather short term exposure will cause permanent hearing loss that depends on where you are in reference to the muzzle and what caliber weapon is being discharged. In a land far far away while doing "Nothing" I had a fellow co-worker discharge a 50 cal above me, I was about 3ft in front and 5 feet below him when the shots (3) were fired and i have permanent hearing loss from it.. Not fun and hurt like hell!

If I'm shooting at a man in my home I don't care how loud it is myself. Loud will scare the hell out of them and while they lay on the floor bleeding out because I used the massive .45 or 10mm his ears will be ringing too.

On that note. I know nothing about good ear protection. What is the best sub $100 earmuff noise suppressors ear muffs?

In spite of what you think, the report from any caliber insdie most modern insulated homes is much less than you will expect. Some time ago, I had a ND with a 9mm indoors. I was surprised at the softness of the report. A family member standing in the yard did not even hear it. There are so many items in a home that tend to absorb sound that your concerns are not founded. I also agree with those that say when fired at a time of great stress, the caliber or decibels of the report will be of little importance.

This^^^^^^

Use a G20 hunting, and even though I carry plugs, didn't have time to install them. No notice of loud report. Although outside, imagine that in a life or death scenario, the report will go almost unnoticed!
