This is a discussion on .40SW v .45 ACP within the Defensive Ammunition & Ballistics forums, part of the Defensive Carry Discussions category; Originally Posted by Metro 40 I'm not sure about the difference in size between the 2 Taurus pistols you mentioned, I don't have any experience ...
No experience in the 40, but say that the recoil is very manageable in my Glock 21 45 ACP and is my favorite pistol.

I think the .40 is less snappy with the 180gr than in the lighter flavors. Makes my G23 feel (recoil wise) more like my G36. Personally I find I shoot my G23 better than my G36 and it's only a hair bigger. This whole thing is very subjective and what works for one won't for another. Rent/borrow/shoot as many different guns as you can (easier said then done I know) it's the best why to decide.
Kimber Ultra Carry II, Glock G23 & G36, Kahr PM9, Winchester 1300 Defender 12gauge pump (my favorite but hard to hide)
I shoot both. A glock 23, 22, 35 and a RIA full size 1911, a Colt 70 Series Combat Commander and a Colt XSE commander in .45 ACP
The .40 S&W with light bullet weights 165 Gr or less have more SNAP then the 180 grs
In the 45 ACP I find that the lighter weight bullets also have more snap but the 230 Grs have more recoil.

The Kahr PM40 has a lot of muzzle flip in my opinion, the PM45 is more of a push and easier to return placement for 2nd shot.

This is as 40 vs 45 equivalent as I can get, my Glock model 39 in 45 GAP and a Glock model 27 in 40. The GAP produces 45 acp ballistics and the guns have the same frame size & barrel length.
Glock 39 + 185 gr. Speer Gold Dot = 932 fps = 356# KE = .77 momentum
Glock 27 + 155 gr. Speer Gold Dot = 1,134 fps = 442# KE = .78 momentum
Although the momentum is nearly the same, my opinion is the 45 has a softer recoil (more of a push, like others have said).
It is a tough call, as one of the reasons to go with the 40 S&W has more to do with capacity IMO. If I lived some place that had a limitation on rounds, I think I would go with the .45 ACP (unless I was looking at sub-compacts for CC).

The relationship of the barrel axis to the grip is a very important factor when talking about felt recoil. A high barrel axis will produce more muzzle flip and likewise the lower the axis the lower the flip. Low axis puts more of the recoil straight back (shove) into the shooter's hand a higher axis gives more leverage to the recoil and raises the barrel with more force (flip) .
I shoot several different .40's, a Sig p226, a Springfield XD 4" and a XD subcompact, I find a difference in them due to barrel length as well as weight, the Sig absorps more of the reciol, yet there is still some barrel flip, I still find my S&W model 66 .357 magnum more snappy than any of my .40's. I have a very bad 1911 clone without grip safety made in Argentina I think, I haven't shot it in a while as it isn't reliable, so I can't really compare the two.
My lighter Glock 27 .40 recoil is comparable to my heavier XD .45 Compact.
The lower bore axis theory is very true. A friend bought a Taurus .40 that had a lot more kick than my G 27. After shooting both, he traded the Taurus for a G 27.
Once again, thank you to everyone for your input.
It is appreciated.

Let's see. When I pull the trigger on my 1911 .45, all it does is go click cause it's empty, and I can't get any ammo for it. Not much recoil there, and no need to worry about control unless I want to use it as a hammer. Here, the all steel 1911 really has some advantages over the Glocks. I can find .40 ammo. So, if I had a gun to put it in, yes, there'd be a lot more recoil, but that would be a good thing.
