    I’m curious about the felt recoil / recovery time shot to shot, between the .40S&W vs .357 Sig.
    In the same size or model of gun, as well as different size gun of same make. Preferably in Glock handguns. Please share your experiences etc.

    I noticed no difference, except accuracy was better with the 357 Sig (No diff in recovery time). That's in BOTH a converted G22 and a G27 (My HD & EDC firearms). However, I am NOT recoil sensitive=Love my G20 in 10mm as well!

    I don't find any noticeable difference in felt recoil, experienced less muzzle-flip with the .357 SIG. Also, the .40 S&W doesn't shoot as flat so in my hands but the .357 was a little more accurate. I only experimented with the G23 gen 3, switching ONLY the barrel and it has fixed AmeriGlo Pro I-dot sights.

    I don't have any Glocks chambered in either .40 S&W or 357 SIG. I do have two SIG P229s with both .40 S&W and 357 SIG barrels and shoot both calibers with both. The all-metal P229 handles the recoil of both very well.

    I would describe the perceived recoil of the two cartridges as similar but different. I believe that the .40 S&W produces a bit more muzzle rise and the 357 SIG a faster push straight back into the hand. I don't find either to be unpleasant or difficult to control and I don't believe that I have the potential to shoot one significantly faster than the other. I am not sure that my offhand shooting ability is good enough to judge whether there is a significant difference in accuracy between the two. The 357 SIG does shoot flatter if you want to shoot at distance. It certainly is louder and produces more muzzle flash.

    There was a time when I perceived .40 S&W to be "snappier" than 9 mm Luger. I just happened to get back from the range where I shot both my Glock 19 and my SIG P229 .40 S&W. I really don't notice any difference in recoil between those two calibers at this point. I would probably be able to perceive a difference if I really concentrated on the recoil. Since I am usually trying to concentrate on things like my front sight focus, sight alignment, grip, and trigger control, I really don't notice one having "more" recoil than the other.

    It’s not the recoil difference. It’s the difference in muzzle blast. .357 is loud!

    40 is my least favorite caliber of all my Glocks. I’d say punishing in the 27.

    I have Glocks in both calibers. I have a G 23 in .40, G32 in .357, and a G27 (.40) with a G33 (.357) barrel. I don't see much difference, if any, in felt recoil. I like both calibers equally. And as someone just said, .357 SIG is LOUD.

    Hope this helps.

    I have the 23 and 32. I did notice a bit of a difference in both recoil and recovery. Then I realized I had different backstraps on each. After changing to same size backstraps, both recoil and recovery began to equal out. Muzzle blast is more noticeable with the .357 Sig...especially at night.

    357 Sig is LOUD, LOUD, LOUD.

    SD numbers favor the 40 in 180gr. My preference.

    I agree that for self defense in most civilian scenarios, 357 SIG offers no advantages over .40 S&W and the greater muzzle flash and louder report may be disadvantages for night shooting or shooting in confined spaces.

    For law enforcement purposes in which barrier penetration might be a more important factor, or long range shots might be required, the 357 SIG might offer some benefits.

    It really wasn't developed for barrier penetration.

    Originally it was supposed to be an auto pistol cartridge that mimicked the 125 grain JHP in 357 Magnum.

    There was an original 150 grain JHP load to go with the original 125 JHP, but it was somewhat slower than the 158 grain 357 Magnum load.

    The original 357 Sig load was made by Federal and was rated at 1250 fps from a 4 inch barrel.

    As powders improved and other companies started loading 357 Sig, 1350 fps became the standard.

    Speer loads a 125 grain Gold ot at 1350 fps and an extra velocity load that is rated at 1375 fps from a 4 inch barrel.

    When we switched from the 22 to the 31, scores went up. Most attributed to the 357 recoiled straight back while the 40 recoiled up.

    I haven't noticed a difference, I shoot many different calibers and it's all the same to me.

    Same frame:
    .40 is more a push.
    .357 is a snap back.
    Not big difference.

    The .40 vs 357Sig are both top notch with the right ammo in my opinion. To me the 357Sig is a very quick recoil straight back, the .40 has a little more muzzle rise but neither is really an issue. I really like the 357Sig round in warmer weather but favor a .40 in the winter months. My issue with the 357Sig is the blast, I have hearing loss and a constant loud ringing in my ears, the thought of the blast indoors taking out what little hearing I have left is worry some. With my subsonic 180HST it’s not so much of an issue. But shooting the 357Sig it seem like those bullets have eyes and always give me tight groups and they get there really fast and hit with authority.

    I have the same ringing. Won’t make a difference indoors with all the AR’s next to you these days. But I may get rid of a brand new g31 I have and fund a suppressor.

    Shoot outdoors. It’s not worth it.

    I have experience with the G23 and G27 with 357 Sig barrels.

    With the G27 size, I have yet to find anyone that enjoys shooting the 357 Sig versus the 40.

    After finding the G27 size sucked, I got a barrel for the G23. Thinking this would be a big improvement proved even more disappointing. I think there’s only been 100 rounds, since I got it, and that was through several shooters. It was over 100 degrees out and the rear grip of the Gen3 was unpleasant.

    In a firefight, the 357 would be great. For fun, the 357 is a waste (especially, since the rounds cost so much more).

    With that said, I am keeping my 357 Sig barrel, mags, and Ammo and wouldn’t mind finishing off the collection for my other 40 caliber Glocks.

    I notice a very slight difference between my G23 with the 40 barrel and the same gun with the 357 Sig barrel.

    The recoil of the 357 seems slightly sharper but it's hard to tell because of the muzzle blast. I like shooting the 40 better but I'm more used to it and have shot the gun a lot more in 40 caliber.

    I've also shot the gun a lot with a KKM 40-9 conversion barrel and recoil with the 9 isn't all that much less especially with Plus+P ammo.

    Ballistically, I think between a 180 grain 40 caliber HST and a 125 grain HST, they're about equal and both are superior to the 9, the 357 by virtue of velocity and the 40 by virtue of greater mass.

    To me, they are both pretty loud. Hard to discern any noticeable diff. YisitreallylouderMMV
