.45 recoil

Gunners,

If one were to fire the same .45 acp cartridge from a 5'' 1911 and a single action revolver weighing the exact weight as the 1911, and a double action revolver weighing the exact weight as the 1911, would the recoil differ among the 3?

The felt recoil in the auto would be less than the two revolvers, which would be the same.

Depending on your grip and hand size felt recoil with a single action should be less than either the autopistol or the double action.
The single action bucks and rolls with muzzle rise that would be a problem with a first follow up with a double action, but the roll back and up absorbs recoil that would otherwise be directed into the web and palm.
The 1911 recoil operation does slow down the transmission of recoil to the hand, which reduces felt recoil, but almost all is directed straight back into the web, with much less muzzle rise.
The modern double action is more of a saw handle than a plow handle, and while very well designed for full control and rapid recovery, directs more unrestrained recoil into the hand. The price you pay for controlability with rapid follow up.

In the end recoil impulse is the same with all, its just how it is transmitted.

I believe where the mass is located on the revolvers may also affect how the recoil is felt. In theory, if you have more mass on top of the barrel, the increased moment of inertia will decrease the tendency of the revolver to rotate in your grip (assuming the same shape and size grip), effectively meaning it would be more of a push than a snap, also allowing you to keep on target better.

Just my opinion.

45s don't have a lot of recoil in either gun, so why worry about it?

You're talking about a .45 ACP. There is no "buck and roll."

In a moderate weight handgun, the .45 ACP's recoil is minimal.

Where are you going to find a SA the same weight?

The recoil from a 'fourdee5' will break yer arm if you don't hold it right.

It just so happens that I went to the range yesterday with my Ruger 1911 and my S&W 1917. Using 230 grain ball ammo. I would say that the recoil sensation was different but not really greater on either on. Now I do use Pachmyer grippers on the 1917 which distribute the recoil over a much larger area that the standard Smith magna grips. Getting a a good fitting grip for YOUR hand makes a huge difference.

I find my Colt 1917 has sharper recoil than my .45 1911s. This is probably partly due to the lack of a slide's movement to spread out the recoil impulse, but mostly due to the fact that the old GI grips on the 1917 do not fit my hand all that well.

Why do you ask the question rmocarsky?

As others have said there is a difference between the mechanical recoil and the felt recoil. If the guns are the same weight (due to longer barrel, heavier grips, etc), the ammo uses the same powder, bullet weight the same than technically the actual recoil will measure the same.

But the felt recoil will differ quite a bit. As you can see from the above posts opinions vary on which "feels" greater or lesser.

As stated, there is a difference between ACTUAL recoil - a simple math equation, and PERCEIVED, aka FELT recoil - which is subjective and will vary among every shooter. Grip style, how it is held, individual hand size, etc., will all play a role in how the recoil is perceived

AN INTERESTING THING is how little actual recoil you do feel from the cartridge firing, as what you DO feel is the slide hitting the back of the frame. I have shot a 45 autoloading pistol with a slide lock and it had all the recoil of a healthy beer-burp, the recoil was ALMOST non-existent.

As a shooter more accustomed to revovlers, the recoil sensation of auto loaders is distracting to me.

Shooting a Colt Government Model .45, I feel first the recoil impulse of the cartridge firing, then the slide contacting the stops, then slamming forward. And, when the last round is fired, the lack of the forward movemnet stop. Distracting.

I don’t quite follow that statement.
Since the same force be it the round firing with the lock or without the lock stopping the slide it’s the same impulse on the gun and the hand ether way. The only difference would be the action of the slide going into battery.
Also the fact that the bullet is well out of the barrel before the hand has reacted from the recoil and the slide has not completed it travel locking the slide or not wouldn’t make any difference.
I shoot a lot of 1911’s and with the same round they all are different. My gold cup is like shooting a pant ball gun yet the same round in my Kimber Royal is brutal. But it’s not the round it’s the fit to the hand. The Kimber is short and doesn’t fit my hand that well but I don’t mind since it’s so easy to carry.
Of all the guns I have shot over 40+ years the only gun that I found uncomfortable to shoot was an S&W 19 with the small grips. 6 rounds and I never wanted to shoot one again. Set of Pachmayr’s and it was comfortable.
Again as so many have said, it’s not the round or gun, it’s the fit to the hand.

Have you ever compared the recoil of a pneumatic air rifle to a spring piston air rifle? The recoil of the pneumatic is almost non existant, there is so little momentum in that 8 grain pellet but the recoil of the springer is quite noticeable even though the pellet momentum is comparable. That recoil comes from the piston accelerating and then slamming to a stop.

My semi auto .22 pistol has a much different recoil feel than my .22 revolver due to the slide slamming back and then forward.

Felt recoil is subjective. All things being equal, the recoil is the same.

Felt recoil is going to depend on how the grips fit you. As others have said, neither should be problematic recoil-wise.

I've fired .45 ACP from 5" 1911s, a 4" 1911, a 4" S&W Mountain Gun (wish I had that one myself now! ) and a S&W M&P45. Of the bunch the M&P kicked the "hardest". A 5" 1911 or the 4" S&W N-frame is a pretty soft-shooting big-bore IMO.

The M&P is both lighter and top heavier than the 1911s and Mountain Gun, so that is not surprising. For its light weight, the M&P is pretty mild, especially if the correct backstrap for the shooter's hand is installed.

With regard to slide movement - it is derived from the cartridge's recoil impulse, and will be less than the initial, raw impulse. It may be distracting to revolver shooters, but it does not and can not amplify recoil.
