G26 vs. G27 Ballistics

Discussion in 'Caliber Corner' started by ES13Raven, Feb 17, 2012.

  1. ES13Raven,

    I would suggest buying a G27 and then later on down the road pick up a Lone Wolf conversion barrel to 9mm, plus a few G26 mags, basically you’ll have both. I’m looking at doing the same after I return from Afghanistan in one month (hoping to get an OD green G27 to match my G22 in OD). Good luck!

    The link for Lone Wolf listed below:

  2. While I can't remember the exact numbers, I did a test between my 26 and 27 using Gold Dot ammo in both. In the 26 I fired 124+p, and out of the 27 I fired 180gr. Then took the average velocities for both and put them into an exterior ballistics calculator. The result was interesting, because the 9mm round yielded less than a 10 foot pound difference (lower) from the .40 round. Another thing I did was to fire both into water, for expansion and weight retention. Both retained 100% weight, but the 9mm expanded to a larger diameter than the .40. My conclusion is, with the right ammo in a 9mm, I feel well armed.

  4. I bought a 26 and later added a 23 for a little variety and added capacity. Both conceal beautifully in Nick Mathews #1 and Gary Brommeland's Max Con V.

    There's no doubting that .40 has a little harder kick so the slightly larger form factor is helpful. 13+1 .40 180 HST is pretty comforting too.

    I did the same, bought a 26 and 27. I set both pistols up with XS Big Dots, smooth triggers and rubber Talon grips. Have had the same expierence with recoil. Can't tell the different between either one accuracy wise.

    The 9mm will stay on target easier. But I have come away feeling confident the .40 hits "harder".
  6. I sold all four of my .40's and went to 9mm's. I have them all; no G18. No regrets.
  7. I will never understand people that think 9mm is not enough.
  8. Either would be a great and, while both have their pros 'n cons, neither leaves the other in the dust, so to speak. The G26 will be more affordable to shoot and, perhaps, be more kinetically enjoyable to shoot as well. I kinda like the G27, but I wouldn't fault anyone who shoots a G26.
  9. The 33 is superior to both. That is what my wife carries. Recoil is no different than a 9mm+p and the muzzle energy is way higher. I got her a .40 barrel for it for Valentines day and couldn't believe how much harder it was to shoot than the .357sig. You can buy .357sig for almost the same price as .40. I feel very comfortable with her carrying that pistol.

    I'm amused how people seem to compare the .40 S&W to standard pressure 9mm and talk about how the 9 is more pleasant to shoot. Compare a 9mm round which is ballistically equivalent, in other words a +P+ 9mm if you want a fair comparison. I'm also confused as to why people want to throw in the fact that you can use standard pressure 9mm for plinking in the G26. Is a sub-compact weapon really your idea of a good plinker? A full size weapon with the reduced power rounds, would be my idea of 9MM plinker. It's heavier and therefore will have even less recoil and a longer sight plane. Be honest with yourselves folks when doing these comparisons. Don't try to compare oranges to pineapples.
  11. Thanks... that is what I was looking for.

    So if I am reading the muzzle energy graphs right, it looks like:
    G26 energy = 280-420 depending on the round
    G26 energy = loses about 20-40 compared to a G19

    G27 energy = 350-500 depending on the round
    G27 energy = loses about 20-40 compared to a G23

    Does that look right?
  12. Yet the resulting argument would be that the 9 rounds of .40 In the G27 would not be enough, which is equally ridiculous.
  13. I totally agree.

    you keep telling yourself that....the last thing i need is a 357 sig round going through the bad guy and into a bystander, or leaving my house and going into the neighbors house....

    btw, how can you say recoil is the same as 9mm, when its a 9mm bullet in a cased down 40 cal shell...

    9mm 127 +P+ has less felt recoil and calculated recoil than 40 in the 26/27 platform. Same with comparing the 19/23. My Glock 32 has been used as a 23 with a OEM 23 barrel almost the whole 11 years I have had it. I got rid of my 27 because I found it annoying to shoot, I like the HK P2000sk 40 much better. 27 is fine for who it works for, I don't care for it.

    In the best LE/SD loading's, 9/357/40 are all good rounds.
    The G27 can run all three calibers.
    And you can use the next size up barrels (4.02") if you want
    the extra ballistics.

    That versatility is the real strength of the G27 IMHO.
    It allows us to individually find the best caliber/round we
    are most proficient with.

    Not paper comparisons of FPS or muzzle energy.

    Putting bullets on target in a high risk, high stress, situation is the key.

  17. You don't think a 9MM or a .40 will go through a bad guy? To be fair that can happen with any caliber if you choose to take the shot.
  18. I would refer to where you put the bullet. A .22 in the the eye socket works better than a .44 mag. in the shoulder. I am showing my age here, but when the 10mm hit the scene years ago, starting in the form of the Bren Ten pistol. They couldn't sell enough to stay in business. A few other manufacturers started making a 10mm model. But they still didn't sell very well.

    At the time S&W pretty much had the Law Enforcement market, almost to the extent that if S&W made a sling shot, depts. would probably issue them. So S&W got an idea to take the the bullet out of the 10mm, shorten the case, use less powder, re-insert the bullet and call it the .40 S&W.

    Police department administrators everywhere wanted the new wonder caliber from S&W. And S&W started there add campaign as "Larger than a 9mm and Faster than a .45"

    Fact is, it's also slower than a 9mm and smaller than a .45 I guess for me personally, it filled a niche that didn't need filled. And I figure that if I had to shoot anyone center mass, they will not be able to notice the difference between the 45, 40 or 9mm. And I do prefer the recoil of the 9 or .45 over the .40. and as much ammo that I shoot, it's saves me quite a bit of money. Just an old farts two cents.

  19. I can say it because I have personally shot all 3 out of the same pistol. Honestly a light .357sig will probably penetrate less than a heavy slower .40. The sig is going so fast that the bullets just don't hold together. I have a good friend that is a police officer and was in a shoot out last year. He was carrying a .357sig glock. The guys shooting at him were in a pickup truck. He unloaded 2 magazines into that truck and only 2 or 3 actually penetrated the sheet metal. They fragment due to the speed.
    I just got back from shooting with some friends this evening. We had between us a full size glock in .357 and 9, and my wife's 33 with all three barrels. We shot them all just to compare. The .40 recoils harder than the sig. It comes down to a heavy bullet vs a lighter bullet. When shooting steel plates the 9 and 40 smushed and flew into the air on impact and the sig vaporized in a grey cloud of dust.
    That's my personal opinion biased on my experience. I don't carry any of those myself. I keep a Glock 29SF with 165g 10mm 1400 fps hollow points with me. :) you know, the way a .40 was meant to be.
