.357 Sig isn't hot 9X19, any more than .357 magnum is hot 9X19.

.357 Sig is a .40 case with a 9mm size bullet, but is not 9X19, and it's faster than .38 Super (depending on the load).

.357 Sig isn't a niche cartridge. It's more expensive and not as widely used, but there are a LOT of us here that carry it, some personally, some professionally, and it's still produced and sold as ammunition and in firearms chambered for the cartridge.

.45 GAP is another matter, and while fresh brass is still available, it never achieved much popularity. It might have been chambered for something other than a few proprietary Glocks, but I've never seen one or heard of one.

.45 acp continues to be wildly popular.

.357 Sig differs, especially in that I can run 9mm or .40 in most of my .357 pistols, in some cases with nothing more than a barrel change, others with a magazine change as well, enabling training with less expensive ammunition and carrying something more capable, as one desires.

The same is not generally true of .45 GAP.

If one can get the ammunition, or doesn't plan to shoot the G37 much, it would be a good deal. Maybe a great pistol to have around the house or to stage as a spare.

The sub $300 gun to get right now is the Walther PPs M2. It’s an absolute steal at $260-280

I am sure they are good guns. But they are in a truly oddball caliber, and that is why they are cheap. That ammo is hard to find, and is only going to get harder to find.

If it was .45 ACP I'd pick one up just because, but I'll pass on the oddball GAP.

Springfield Armory offered the XD in .45 GAP for a few years in the mid/late 2000s. That's the only commercially available non-Glock .45 GAP semiauto I'm aware of.

SA Inc. also toyed with the idea of a micro 1911 "Defender" in .45 GAP, and produced a few prototypes around that same time frame, but that never went into commercial production. They eventually transformed the idea of a shortened frame micro 1911 chambered in a smaller cartridge into the "EMP" that was chambered in 9mm, after SA Inc. gave up on the .45 GAP cartridge.

Bond Arms offers .45 GAP barrels for their derringers.

Yep, I had one. Bought it used for $200 and was happy to sell it at a loss. Wasn't impressed at all.

Just got my "shipped" notification. I am supposed to get it Wednesday!!!

That is a good deal but I don't see it (the caliber) lasting long. The price of ammo isn't cheap from what I have found.

It's not cheap compared to 9mm rounds but it's all relative. I found some JHP for about ¢45 per. I'm going to buy 500 hundred rounds, empty a couple mags to say I have shot a Glock, and put it in the safe.

I don't plan to shoot it much and it won't be my EDC. I don't care for the trigger safety, and I prefer hammer over striker. But I have never had a Glock, and I would never have bought one without the opportunity to get one cheap. The time was right, I had the money, eh, why not?

The 45GAP looks like a great round and a good use of modern powders to reduce case length. To bad it never caught on.

I had one of those too. It was a good gun. I sold it because at heart I'm really a 1911 guy and don't really care for striker guns. You can reload GAP brass with the same dies you use for .45ACP, using the same components.

These are probably from the NYSP. They are going to Glock 21 pistols. Actually I think they are already all issued. I know the guys I routinely work with have them.

I didn't know that. Hmm... I wonder why they didn't do that in 2007.

Of course they are only sending the gun with one mag. But, if you want another, you can order used mags from them separately. Cuz they fell into a boatload of them. What a coincidence!

I wonder why 45acp is so popular with State Police Agencies. Mass State Police M&P45, NH State Police M&P45 and NYSP G21. In my area troopers are few and far between and the nearest backup is not close but they carry a pistol with a 10rd magazine.

Ironic, coming from someone with your username.

I don't work in a free state!

Highly doubt these are former NYSP guns, as there is a law in New York former police guns can not be resold to the public- have to be transferred to other agencies or destroyed. Which is why I was very surprised to see former New York State corrections guns being sold lately. Perhaps there is some loophole since the dept of corrections is not technically police? Not sure. When the troopers got the gap the corrections department slowly transitioned to the hand me down Glock 17’s.

Let’s be honest here - some crazy world event catapulting 45GAP to the forefront as the only round able to stop alien space invaders notwithstanding - in 20 years the round will be long forgotten.

Yep. It will join the .41AE in obscurity.
