FN 5.7 and Glock 38
#1
So finally I shot our FN 5.7 today for the first time. It was pretty cool! Although I've been trying to look things up online and try to figure out how it is a good self-defense pistol when it *feels* like shooting a step up from a .22. haha. And the holes are so tiny! Do all the bullets go base over tip when they hit the target, or just certain ones? Is the ammo available to civilians still good for home defense, or just the military ammo? I would love to use it as home-defense but it just doesn't feel like it would have much knock down power. But I don't know....

Shot our Glock 38 for the first time too (now THAT one feels like it has knock-down power!)...didn't like that one as much--grip not comfortable in my hand--although it shot nice. Although I guess the ammo is going to be harder and harder to find. I guess we should just start trying to stock up on the ammo when we can? The guy at Classic Pistol said that right now the local cops use the Glock 38 but they're moving away from that ammo, so then it will be a lot harder to find, if not impossible.

Both guns were actually sort of gifted to us, so that's why we even have the Glock....I figure it would be better to stock up on ammo and just keep it around than try to trade it in for something else. Hopefully they still keep that GAP ammo around for another year or two though.

Okay, I remember when you got the 5.7. I confess, I don't think I would have had the patience to wait this long to shoot it. My fear using one for HD would be over-penetration. Those little puppies are designed to rip through body-armor (and in some cases worse, but you can't necessarily buy those rounds). They're probably going to cruise through a lot of wall-board and siding.

You can still find .45 pretty easily. I recently found some priced something like normal from Freedom Munitions. Now to find it, I had to keep the gunbot.net app running in the background on my browser, and wait for a "ping." The Freedom stuff is beautiful; the only fun part is looking on the casings and seeing every which brand (it's very well-done reloads; better than cheap steel-cased grot at the same price).

I know! We had planned to go right away, but then we had a sick kid to stay home with, and after that, various and assorted scheduling difficulties. Finally!!!!

I was looking it up and it looks like the body-armor piercing ammo is not the kind we can actually buy as civilians? And I read on Wikipedia (okay, I know...) that this bullet actual leaves less collateral damage than other ammo due to it losing effectiveness faster than regular ammo. Supposedly it loses momentum after like 400m as opposed to other ammo's 800m....????

So my question is....if it makes such a small hole, and it leaves less collateral damage to your house....will it stop a bad guy? If so, I would totally love it as our main home-defense, because of the ease of shooting it. But it just didn't feel like a knock-down gun...well except the major flash shooting out the front, that part looked pretty cool.

Good to know that the GAP .45 should be around for awhile.

Shot place is key. Any round will kill more people are killed with the lowly 22lr than any other round.

Right...but for home defense, you may as well choose one that has a good knock-down or stopping power.

I know the Glock would be good, but I'm more comfortable shooting the FN 5.7.

There is a thread here somewhere that heavily discusses the 5.7 that was made by Valorius. The 5.7 target round is pretty much a target round. There are aftermarket rounds from Elite Ammo that are made specifically for home defense. The are fragmenting hollow points. The penetrations of these aftermarket round are substantial, and the very high velocity of these rounds will penetrate body armor and cause very large wound channels. I can say that the nature of this pistol makes shot placement extremely easy, and a 21 round capacity makes it a solid choice in the event of multiple bad guys.

The bad news is that like every other caliber, 5.7 ammo is hard to find.

The good news... if you want a mag full, pm me and I'll give you 20 of the Protector rounds.

Quantify "knock down power"?

Kinetic energy is the only way I know how to put a number to what a hard hitting round is. A round that is less than 200gr going slower than 1000ft per second may have less than 500 foot pounds of energy but what does that actually translate to? I have heard that a 147gr +p 9mm rounds fired from 10 feet feels like a 5 pound weight dropped from .75 inches assuming is does not pass through you. However that being said, I have seen a .32 auto fired at 5 ft into a bullet proof vest put a welt on a person that will last for weeks and it may have caused permanent blood vessel damage.

I guess what I'm trying to say is that there are so many factors that are involved in a shooting that calling it controlled chaos falls short of properly describing the vast variables involved in what could or does happen. Tried and trued methods are heavy bullets with a lot of powder to burn, they seem to make the best rounds for incapacitating your target. Killing them doesn't matter as much as making sure they can't physically get to you. The 5.7 has very little solid testing evidence to suggest it will penetrate enough to sever nerves. I know equally less about the 45 gap but I would imagine that it has more of what is tried and trued in its development.

Its your call in the end, I err on the large side.

I know this is an old thread, but I just came across it, so it's new to me.

One thing I haven't seen mentioned is the velocity of the 5 7, between 2000 and 2800 feet per second. People, that's RIFLE quality hustle.

I'm pretty sure a 5 7 would be more than adequate to stop a bad guy (or gal) in their tracks. I would make an informed choice of bullet selection because over penetration is a real problem with such a hot round.

Over penetration isn't an issue, either in flesh or in case of a miss.

We did end up selling the 5.7. Needed the money.

And oops, that should say Glock 37.....
