Glock 9mm or 40 or 45?

Postby TheWanderer » Thu Jan 27, 2011 10:04 pm

I know I'm getting a gen IV glock since it fits me well and I shoot them well, but I can't make up my mind about what caliber to get.

What factors made everyone elses decision on caliber choice?

It'll be a home defense handgun. Occasional target practice.

The 9 and .40 are the same frame, so they feel the same in the hand. The .45 has a fairly bigger frame and feels blocky to a lot of people. Handle them and get what feels best. If it comes down to the 9 or .40, I'd go with the .40. It has nearly the same recoil as the 9 to me and has a lot more stopping power (hence why no police departments carry 9 anymore other than litterally a few).

Personally I prefer a 45 but between the 9 and 40 I'd definitely go with the 40 to have more energy with larger frontal area.

I prefer knock down power so I'm a .45 fan. However, the 9 and the 40 would be much cheaper to shoot.

Mostly home defense ..... go with .45 or better yet a shotgun.

.40 cal was designed as a trade off between the capacity of a 9mm and the energy delivered by a .45. Most PD's opt for .40 but a lot are switching back to .45 as the capacity is not such a big deal and the .45 is a better manstopper.

Preach said it well. For a home defense gun, I would go with the 45, but like preach said its going to be on a slightly bigger frame so make sure it fits you well.

If I had to choose between the 9 and 40, I would take the 40 for defense purposes, but might pick the 9mm if I planned to go to the range a lot with it since 9mil ammo is a lot cheaper. Again for strict home defense, 45 hands down. Tactical shotguns are fun too.

Yep, the 9MM for when your grandchildren need to learn how to shoot, and the 40 and 45 for protection.

If your buying for home defense, IMO you have to go for the knock down power with the 45. Second would be the 40 (which for all practicle purposes will do just fine) and the 9 mm brings home the bronze. You can get 9 mm rounds much cheaper, but one 45 round center mass and whoever is in your house is no longer a threat. Thats why as stated above most law enforcement agencies are ditching the 9 mm and going to 40s and 45s.

I have owned all 3. I have to say that the .40 is a good comprimse. They have less recoil than the .45, and seem to be very effective man stoppers.

Having said that, my .45 acp is my go to gun when things get rough.

Believe it or not, there isn't a whole lot of difference in permanent wound channel when using a quality hollow point in 9mm, .40, or .45. An example of a quality hollowpoint would be Speer Gold Dot

Carry what you can shoot best and what is most reliable.

When carrying an auto, I alternate between a Glock 19 (9mm) and Glock 30 (45) and I carry in-waistband using a Crossbreed Supertuck. No real pattern to whichever one I choose. I carry a 642 in a pocket when an auto of that size is impractical.

The 19 holds 15+1, the 30 holds 10+1. The 30 seems a little bit easier for me to conceal and is a little more comfortable, but that could be because I just haven't gotten used to the 19 yet (recent purchase). The 30 is slightly wider, but it is just a bit smaller in length and height than the 19.


The 19 is WAY cheaper to feed as far as practice ammo goes, so if you are only buying one, that almost automatically makes it the better choice.

This is an interesting link that finds the .40 to be a tad better than the 9-

Wound channel is definitely one part of the formula and the differences in the hole made by a 9mm, .40 and .45 may not be THAT dramatically different. But an all important factor when it comes to paring down a defensive round is energy transfer .

Looking at the heaviest loadings of each caliber with Federal Hydra-Shok loads for example (147gr in the 9mm, 165gr in the .40 and 230gr in the .45) the difference between the 3 becomes very obvious...
45 vs 40: the .45 has 18% more energy at the muzzle and 20% more at 25 yards- a significant difference
40 vs 9: the .40 has 8% more energy at the muzzle and 6% more at 25 yards- a difference but not huge
45 vs 9: the .45 has 27% more energy at the muzzle and 28% more at 25 yards- not really a fair comparison

Looking at the other end of the spectrum with the lightest loadings (124gr in 9mm, 135gr in the .40 and 165gr in the .45) the numbers mix a little and the .40 really shines....
9mm: 345'# at the muzzle and 315'# at 25 yards
.40: 432'# at the muzzle and 373'# at 25 yards
.45: 412'# at the muzzle and 377'# at 25 yards

With lighter projectiles the .40 actually surpasses the .45 at the muzzle and is virtually equal at 25 yards while both dramatically outweigh the 9mm with approximately 20% more energy at both distances. Knowing these differences between the 3 rounds and having the option of either, it is obvious that the better performing round does in fact begin with a 4.

This does not even factor in another very important factor of a projectile...that being the tissue shock damage surrounding the entrance or wound channel. Basically a larger projectile does more terminal damage due to the larger frontal area and more energy transferring into the target.

One other note is that within the realm of the "4" calibers, the .40 is much more of a "snappy" round to shoot meaning the recoil is a quick, sharp jolt while the .45 is more of a heavy shove. Many compare them like comparing a .270 rifle with a 12ga shotgun. Personally I have both and like each for their own merits but my primary carry piece is a .45.

Therein lies the rub. A round having more kinetic energy does not necessarily mean it will be transferred into the intended target in a meaningful manner. i.e. more KE doesn't always equal more 'knockdown power' (whatever the hell that is.)

Second, you allude to temporary wound cavity in your post. Organs are elastic, and probably absorb most of the energy imparted by a pistol bullet with minimal damage despite the impressive looking temporary wound channel. I would wager that the majority of the effect a pistol bullet causes is a result tissue of being crushed through contact with the bullet itself. So, sure, a .45 expanded to .7 and a .355 expanded to .59 results in a 27% larger area of "tissue crush" for the .45, but chances are that either one placed center mass is going to have the same effect.

I think we are in the same book but on diferent pages. With defensive ammo being designed to prevent through-and-through penetration this allows all of the KE to be expended within the target in most cases. If the bullet does exit this opportunity is obviously lost and the damage is dependent upon the size and location of the wound channel.

As far as the elasticity of organs and tissue goes, they definitely are but the shock wave of the projectile's energy being dumped in a micro-second within the body cavity causes severe damage above and beyond the resiliancy of the tissue to withstand. I have seen tests using ballistic gelatin torsos molded around a skeleton and pig organs and the results were drastic. Even with the projectile missing the major organs by a few inches the heart and upper lungs basically exploded from this shock wave.

This subject can be debated forever but it is safe to say that the 9mm, .40 and .45 rounds can and do produce destruction when shot into a human at close range....the .40 and .45 making more damage due to larger frontal mass than the 9 but all 3 are lethal.

All are good points. If I knew I had a gun fight in an hour, I would have my 1911 ready to go. My carry gun is a Kahr .40 and what is next to my bed? A .357 mag revolver...all will get the job done.

Realize might be a little late as the thread is a little old, but I'll put my 2 cents in. The OP sounds a little new to handguns based on the question so I would recommend a 9. The most important thing for you is to practice because the best defense gun is one you are familiar with and can shoot well. The 9 will allow you to shoot a lot more for the same amount of money. It will also let you practice more during each target session. What I mean by practice more is "good" practice before you start getting tired and sloppy.

Ballistic evidence shows a heavier bullet will produce greater, more destructive wound channels. The heavier the better in each caliber.

Also, whichever one will reliably feed, fire, extract, and eject in your gun.

If I knew I was going into a gun fight with advance notice, I sure as crap wouldn't take a handgun, no matter what caliber.

I would grab a long gun.

There is one international sound that 99% of the population can identify and that's the sound of a pump shotgun chambering a round. If you have enough time to reach for a pistol you have enough to chamber a 12g. round. Nobody is going to stick around long enough to find out what comes next. With that being said, consider what the ramifications will be if you pump a .45 round into your neighbors kid because he came home in an alcohol blackout and opened the wrong door. First your gonna need a lawyer and second your gonna loose your right to carry a firearm. I know for a fact that I never want to pull the trigger on another man and will avoid it at all costs.
