Depends on the gun.

Generally speaking, it doesn't make much of a noticeable difference to me.

45,,but depend on size of guns,barrel lenght,metal/polymer pistol etc

.45 but it's a better feel almost like it pushes back not up. IMO

i like .45 better, .40 cal is a bit to snappy.

Depends on the gun.

Poly frames feel a little more push to my hands... from 9m, to 40, to 45. Metal frames seem to roll with the punches.

I don't mean to be a grouch, but this question isn't really answerable as posed.

First, since there are lots of different loads for each cartridge, you'd have to say something like "which cartridge generates more force, the Winchester 230 gr FMJ .45 ACP or the Winchester 180 gr FMJ .40SW?".

And, even if you were specific about the particular loads/configurations of each, there's a technically correct answer, which may have nothing to do with the "felt" or "experienced" recoil, which is what most of the world cares about. And that has a lot to do with the weight, shape, and material of the gun(s) used to fire the cartridges.

My subjective impression is that .45 ACP, in general, produces a "stronger" recoil, but .40 S&W produces a "sharper" recoil, which I sometimes find more unpleasant than the recoil of a .45. I have no idea if there's any underlying physical reason for those perceptions, that's just what I notice when I shoot them. Of course, I can't shoot them out of the same gun - the closest I can come is, for example, .45 ACP in a Glock 21 and .40 S&W in a Glock 22. The two guns are similar but I'm pretty sure the recoil springs are not identical, and the slide weights aren't going to be identical, so it's not really an apples-to-apples comparison.

If you or someone you know is trying to pick out a firearm, the best thing to do is go to a range where you can rent the gun you're thinking about and give it a test drive. I can think of a couple of guns I thought I wanted until I tried shooting them; and I can think of another gun I wish I'd tried before buying. (A Browning Hi-Power in .40 S&W - bought it in a hurry when someone said they said they weren't going to make any more, which turned out to be false.) It's a nice gun, but it's not a good match for my hand geometry and it'll cost a couple of hundred bucks at least to get it modified so it's comfortable for me to shoot.

The 40 is more snappy, the 45 is more of a push.
I, as most others, prefer the recoil of a 45.

Depends on the gun, though all things being equal they are about the same. the .40 tends to have a quick snap while the .45 tends to be more of a push. think of it as the diference between a punch and a shove, the actual ammount of force is basicly equal, its just a matter of how quickly it comes.

.45 ACP is a baby kitten compared to .40 S&W

I would say 40 has way too much snap for my taste

This is exactly right. Recoil depends on a lot of things. Size of the gun, what it is made of, recoil springs, weight of the bullet, what kind of load is in the casing, etc. These kind of questions are so hard to answer and someone who hasn't fired a lot of either might not know it. Oh, and one other things that contributes to felt recoil... Ergonomics. You might not think so but it's true. If the gun doesn't fit you well then the recoil will feel stronger.

IMO, 9mm == .40 == .45 in terms of recoil. I could even lump 357 Magnum in there (I shoot the latter from a 6" GP100 and it's very comfortable, but I've also shot it from a 4" with wooden grips and it becomes a different beast.)

This is echoed by subjective tests among newbie shooters who try my all metal CZ75B 9mm and say "wow, that kicks a lot!" Gun reviews tend to say "recoil is negligible on the CZ."

The gun is definitely the deciding factor. On Monday I get my Steyr M40-A1 out of jail, I'll get to find out if it indeed tames the .40 :D

Is going from a .40 Glock to a .357 SIG one (like changing out the barrell on a Glock 22) going to make for a noticable difference in recoil?

.45 in general has more recoil but the snap of the 40 isn't for me. Ill take a 45 over 40 any day of the week.

I must be getting old, don't really notice the 45 any more, its more of a shove than the snap from a .40.

.40 cal feels more snappy to me.

I agree with depends on the gun.

Most recoil is vastly overstated, especially for 40s unless the gun specifically is not made properly to handle the caliber.

If you can't take a recoil of caliber mentioned, you need to lift weights.

What he said! :D I find it easier to double tap with my 40s a sharp snap, but I love the feel of my 45 more.

You gotta shoot them for yourself and decide...

I prefer 45, but if must shoot a 40 cal shoot it at 185 grain, it takes the annoying snap out of it.

many of u says depending on gun.

then say it is Glock 21 vs. 22. same type of guns, barrel length, so on...

only question left would be bullet weight. it should be the bullet weight that produce same velocity. or just same bullet weight.

The .357 SIG is even snappier, is louder, and has more muzzle blast.

It also depends on the quantity of powder and its burn rate.

Absolutely.

A heavy bullet on top of a small charge of a fast burning powder (45 ACP) is going to recoil less vigorously than a lighter bullet on top of a larger charge of a slower burning powder (40 S&W).

owned both guns- kept the G21 and sold the G22 because it felt a little too snappy. i used a variety of loads through the G22 but the experience was pretty much across the board that the G21 recoil feels less intrusive.

.40 S&W tend to "snap" more than the .45 ACP by most account. One reason is because most .40 caliber pistols are using frames originally designed and sized for a 9mm pistol. While most .45s are designed and sized from ground up for that caliber, and significantly larger/heavier in most cases than its .40 caliber variant.

I'm sorry friend, that's still not the only factor. As others have said, bullet weight, charge, etc are all factors.

If you can, go to a range, rent them out and try them.

Both have noticeable, but different recoil as stated by others before me so I won't repeat what's already being said.

I, personally, like the recoil of the .45ACP better.

Dunno. Never fired a .40. Why would I? I have a .45.:D
