I am not very recoil sensitive but have noticed that the .357sig and 40s&w have a bit more pop than a 9mm. The .357sig is loaded to a higher pressure and the bullet flies very fast and straight. However the .357sig ammo is much more expensive. I find myself running 9mm thru my glock 23 conversion barrel for this this very reason.

Btw, I carry my 9mm lone wolf conversion barrel in my glock 23 with no hesitation whatsoever. I have fired over 500 rounds without a single jam or ftf.

Why not just carry a Glock in 9mm from the get-go? This has potential to be exploited by a lawyer if you use it in self-defense. "This round is more lethal and not designed for this gun!" "This man wanted a barrel in his gun that could kill better!"

I guess I could be exaggerating but it's a possibility.

My M&P core is more fun to shoot with the 9mm barrel but it says "40" on the side, so that is the barrel that sits in it on a daily basis.

Please enlighten me on what the 10mm was originally designed for.


Originally envisioned as a do-all combat round.

Maybe the recoil was a myth and maybe it wasn't, but no one can argue that the 40 did not start off as a full power 10mm.


Recoil was in the ballpark of the .45ACP in similar weight guns. So hardly a bruiser. The .40 S&W did not start off as the full power 10mm Auto loadings. Started as the lighter FBI loadings. In fact, today most commercial 10mm Auto isn't loaded nearly as hot as the original Norma loadings. So pretty much everyone harping about how strong 10mm Auto is, is shooting neutered loads that brought about the .40 S&W that they deride. It's very funny really.

220 grain hard cast. 1300fps. Death.

That's a good load.

Unfortunately most of the good stuff is watered down. Almost all .357mag, 357sig, and 10mm are powder puff loads. The real shite they were designed for is good stuff. I'm a big time fan of buffalo bore.

FIFY

Either somebody fibbed on that load or you are in need of double checking your setup. That's WAY above safe. 1200 fps at 220gr is pushing it.

What some call a "combat round" is nothing but a glorified term for a self defense round. No one in their right mind would willingly go into combat with nothing more than a handgun, when they could use a rifle. As Colonel Cooper said. A handgun is just something to get you to a rifle or shotgun.

This may be true for some, but when I speak of a particular round, I mean what the round was originally designed to do. Not what some lawyer says is the "lawsuit proof" loading. The 10mm Auto, in its original form, launched a 170 grain bullet at 1,300fps or a 200 grain bullet at 1,200fps. When I load for my SW 1006, these are the ballistics I try to achieve and do, quite successfully.

When the top loads of 40 s&w are used it has very similar energy to the sig 357. Calibers are pretty close and equal.

Buffalo bore:

40 s&w = 155 grains, 582 lbs/ft
357 sig= 125 grains, 564 lbs/ft



Those are some hot rounds. I have this for my 40 s&w. If I did not own a 357 mag I would not hesitate to use my 40 s&w for my woods gun.

I'm in late and haven't read all posts but.......


357mag is my favorite . It is because it is a high power round In a wheel gun that you can load however you want. Putting it in a da gun is a moot point

Well - .357 Sig rounds should fit your factory G23 mags just fine


Isn't the case on the .357 just a cut down .40 with a bottle neck on it?

I've had a 10mm in the FBI Smith model 1076 and a gun that heavy and in my case inaccurate had to be very unpopular with the agents. It probably had to be larger and heavier to handle the dynamics of that cartridge. The 357sig is in a Glock and my car gun - very accurate and not much recoil. I also have a sig 229 in 40 and it also is accurate but to me has more recoil than the 357. Another consideration is being able to find ammo - 40 is everywhere, no so 357 sig and 10.

Yea pretty much. It's a little more complex than that but for all in tents and porpoises it's a necked 40

This is a very hot round loaded above SAAMI pressures. Buffalo Bore even warns against using these in unsuppoorted chambers such as found in Glocks.
