Opinions on the glock37 .357sig

The Air Marshal's guns are .357 SIG as well.

That surprises me based on the penetration factor alone.  Bill T.

The .357 SIG is a fine round. I have a SIG P239 in .357 SIG which I bought for more punch that I get from a 9. I also have a .40 barrel and several .40 magazines for the pistol. The .357 SIGs will function in the .40 mags but the .357 mags have a shoulder that prevents the .40 from functioning in it. That may be a SIG single stack only issue. I under stand that the P226 mags are the same for .357 & .40 but they are double stack and the P239 mags are single stack. I use more .40 mags than .357 for practice, but when I carry I use the .357 mags.

The best recommendation I have heard for the .357 SIG is that it is what the Secret Service uses even though the Justice Dept is a .40 outfit for most. Another biggie is that the Texas Rangers use .357 too. If it is good enough for those guys it is good enough for me.

The Air Marshal's guns are .357 SIG as well.

I use a Dillon 650 to reload the .357 SIG and shoot quite a lot of them -- obviously. That keeps the cost down. I got most of my empties for free several years ago and am still working on them. It is a good round and reloads well. I do not reload the .40. And have rarely fired it with that barrel in place. I am not a fan of the .40, which is a good round but I prefer others.

Thanks for the info stryker. I was wondering about how far the two could be interchanged. You answered the question. As far as SS using the round? Those guys could give a rat's ass for collateral damage for obvious resons. The Air Marshalls? WTF?

The advice I give people who ask me about .357 Sig, is to suggest they should go over to our ammo area and look at the stock of .357 Sig rounds.  We don't carry much stock and it is more expensive that other rounds.  I advise people to either reload or buy 9mm, .40 S&W or .45 ACP.  However, several people buy Sigs in .40 S&W and then get a .357 Sig barrel.

If you buy a 357 Sig, make sure you buy a 40 barrel for it. At least you can shoot it when ammo supply becomes an issue.

The Secret Service is a LE agency just like any other fed LE agency, collateral damage is a concern for them as it is for anyone else.
Wouldn't look too nice to drill the bad guy and kill the Head of State of Whogivsashitz.
We'd probably end up writing an even BIGGER check than we were going to give them in the first place.

Bullet construction and velocity determines penetration. A bullet made to break up like a bomb will do so if pushed fast enough. If it's 'bonded' its still a bomb but will go a little deeper. Inside an aircraft is no different than a bus, train, or school. Dump enough energy and even if the round gets through, the likelyhood of it doing fatal damage goes way down.  
The Air Marshalls are supposed to be at the pinnacle of handgun proficiency. Don't know for a fact, just read it somewhere.

There was an article about tungsten bullets. They were supposed to powder upon impact and do massive damge without penetration (and only $3 per round! ). I would hope Air Marshalls would be using something like this. Honestly though, I'd rather work midnights as a crime scene clean-up guy than have to fly commercial and stay sober. That's my own version of hell.

To answer a couple of questions i saw in this thread, the Air Marshall's use a fully fragmenting round similar to the Glaser blue round that was developed for them even though the worry of over-penetration has been somewhat exaggerated. The 40 & 357 Glocks are identical except for the barrel and markings. All parts will interchange and you can swap barrels either way. The same magazine will work for both but the 357 would chamber and fire in a 40 barrel (not sure what would happen in this case and don't want to be the crash test dummy either) where obviously 40's would not chamber in the 357.

I wouldn't voulunteer for that test either. As far as .40 to .357 SIG?
Probably just bad accuracy. I owned a Blackhawk in .357 that had a 9mm cylinder. It worked fine, but the accuracy suffered. It was more of a gimmick than practical, but it did give you a fall back option.

The big question about .357 Sig is, "...WHY?"
I don't get it and probably never will.

Does the interchangability of the .357 SIG go both ways? I know you can shoot .357 SIG out of a forty (with a different barrel). Is the reverse true?
FQ13

the 357 sig is a 40 sw necked down to .355( aka 9 mm)  every gun I know of its just a barrel swap.  There might be a few you have to change the recoil srping, but I doubt it.

My M+P .40 full size mags, also have a "/" for .357Sig. I have pondered and scrounged pennies for a .357Sig barrel, but based on ammo prices for the .357Sig round, a 180gr.  JHP should be plenty in .40.

Kinda like the 10mm, great round, no question,...41 Magnum the same, but in today's day, I need the price point to meet the want.
