    I just put an oem + base plate on my .357 sigs to gain my lost round back.

    I could be wrong, but to me .380 is a little under-powered.

    Funny Fact: Last night I was watching a new unsolved series on Netflix and a detective from Norway said that 9 mm was not a typical defensive caliber but was more of an assault caliber! Does anyone know if Norway is on planet earth?

    As for .38 special +P, .357, 9 mm, 40 S&W, 45 ACP, I have carried all of them and think all are adequate as conveniently carried handguns go.

    A lot of countries won’t let citizens own calibers their militaries use. Which is why Glock made the 25, & 28 years back.

    Have all the mentioned calibers in autos & revolvvers. Prefer .45 acp when concealment is not a concern. A G21 or 1911. Concealed, 9, .40 in a sub compact auto. A G27, Shield or LC9s. Revo, LCR .357 snub.

    Simply stated, the lower the power factor of the cartridge, the more care that must be exercised when choosing a self-defense round... with the focus being the expected performance of the bullet.

    The .380 Auto has just a few commercial self-defense cartridges that perform well... but they do exist. :)

    Definitely less than optimal imo as well. But as RBBeers pointed out, the best modern loads are tailored for their specific platforms. IE, a .355" jhp loaded for 380 will be substantially different construction than a similar-weight .355" jhp loaded for 9mm or a .357" jhp for .38 special, etc. A long time ago, mfr's tended to take the same bullet and just push it faster to achieve "better performance"; now if we shop around we can find loads specifically tailored for the velocity they're used at.

    While some calibers are definitely more capable than others just due to the amount of raw power they have on tap, the gap between calibers nowadays is not only closing, it's to the point where there's a lot of actual overlap in a lot of cases. If I'm pushing a 35-caliber, 90-110 grain bullet, at between 800 & 900 fps, am I shooting a .380 or a .38 snub? Could be either, yet as a society we tend to think of the .38 special as 'more capable' than the 380. I used to carry a J-frame revolver as a primary, and the much-smaller LCP carried as backup in my pocket now is not only nearly as powerful, but holds 40 percent more ammo. If I could consider the 5 shot j-frame as acceptable (which I did), I don't know how I can think of something ballistically similar and 40% higher capacity as less than acceptable.

    Similarly, the .45acp I used to carry (Federal 185 grain at a measured 816 fps from my gun) was actually less powerful than the 9mm I now carry, so going "down" to the 9mm doesn't bother me at all - as long as I get to pick the ammo in it.

    I tend to want 'more' as most of us do and not pushing the .380 as the best defensive round or anything; my main edc gun is a 9mm and will probably continue to be for a long time. But just saying that if I'm allowed to pick the load and the launcher, I'm comfortable with a wide range of specific calibers.

    The 365 really killed the only reason I ever carried a .380.

    With so many small 9mm guns out there, 9mm is the way to go. The P365 changed history.

    Wonder how that P365 pairs up to a G26?

    It is close enough for me to keep the G26 in a holster.
    I shoot my G26 better than my other Glocks and I have no idea why.
    G17 has an RMR cut with a red dot and I still shoot better with the G26?

    My guess is 'fit'. :)

    The contours of the backstraps of the different size Glocks (standard, compact, and subcompact) are... well... different.

    For example, the G19 backstrap compared to the G17 is shown below.

    G17 Gen 4 vs G19 Gen 4 backstaps 1b.jpg

    The differences between the G26 and G19 backstraps are similar, the stocks are just shorter.

    Simply stated, as the stock shortens, the 'Glock hump' at the bottom of the stock moves higher in the palm of the hand... affecting 'fit'.

    'Fit' is much more important than many realize. o_O

    It seems that the G26 stock fits you very well. :D

  16. UNLESS the smaller 9mm hurt to the 365 and Glock 43 and Ruger LC9 did for me.

    Not a fan of taking it to the range, shooting one magazine 'just to make sure it works'..grimacing and putting it away. I shoot all my guns, gotta be FTS(Fun To Shoot) ensure reliability, and competency with any of these I own. And to have fun....

    I get tired of preaching to some people about the weight of the projectile VS barrel length.

    I have little interest in 180gr .40. The way they lightly load it that round frequently doesn't cross the expansion threshold. What it does out of my G22 VS my G27?

    Same thing with 230gr .45acp. I'll go lighter for more velocity.

    A friend has a P90 Ruger (.45acp) 7+1. I would take that in a HD scenario vs his Ruger 7 shot .357. He thinks that one shot from a .357 is going to magically drop the bad guy. I'm not Jerry Miculeck, I can't shoot and reload that fast. Multiple invaders in a house in the country is a very real scenario. He has his carry permit and never carries on his person. He's a big boy and used to fight mixed martial arts. I don't want to get up close and personal with the bad guys.

    My G45, or my Extar9 do the HD duties. I have a fenced yard with 3 big dogs. I can get to much more violent weaponry in a few seconds if needed. Multiple loaded AR's in the safe including a x39 10.5" AR47.

    Really?!?! o_O

    Smith & Wesson M&P Shield 40 S&W Short Barrel Ammo Gel Test (HD)

    While the Hornady Critical Duty bullet (in the video above) under-expanded and over-penetrated, note that the Critical Duty bullet is designed to penetrate barriers, which requires a 'tougher' jacket. The Critical Defense bullet has a 'less tough' jacket and is designed to expand more and penetrate less. Accordingly, my guess is that the Critical Defense round would've performed more in line with the Federal Tactical Bonded, Federal HST, and Speer Gold Dot cartridges.

    Given the results of the testing above, credible references pertinent to modern self-defense cartridges that support your 'concerns' would be greatly appreciated. :D

    That Taurus TX22 beats the snot out of the G44 in all categories. Like I need another .22! :rolleyes:

    The difference is in thickness. The G26 is 26% thicker than the P365.

    Imagine if your belly were 26% thicker.

    The G26 is a great shooter.

    At least for me it is because of recoil management. With the 17 and 19, the grip sits lower in my hand and flips when the round is fired.

    With the G26, the grip sits in my palm and pushes straight back when fired.

    That along with a thicker grip as compared to the P365 makes the G26 a great shooter.
