Anyone running with an FN 5.7? I'm considering getting one, but the last FN pistol I handled had a horrible trigger pull. I am mostly interested in the 5.7 round. What types of rounds are available now? In all reality my biggest threat would probably be a mountain lion or problem brown bear. What kind of trauma could the 5.7 cause in large game? Would the velocity be to slow out of a pistol length barrel to fully reach the benefits of this round? Would I just be better off sticking with a .45?

Thanks in advance
 
Re: FN 5.7 Thoughts?

Ha! It has the energy of a 9mm in it's wettest dreams. I'll add a linkie but in summary 21 ft/lbs more than a 22wmr in comparable barrel lengths.

Buying the FiveSeven vs virtually any conventional centerfire full size pistol is a joke, save capacity. They do pack a lot of those tiny rounds in.
 
Re: FN 5.7 Thoughts?

If you want the high capacity but a cheaper and more effective round, get the XDm in 9mm. It will cost several hundred fewer dollars and it shoots ammo you can buy at WalMart. It will also deliver a lot more energy on target and, with good hollow-points, expand to nearly double its starting diameter.

If you want a high-velocity, low-recoild pistol, I would get one of the Kel-Tec PMR-30s. With CCI ammo they are very reliable, hold 30 rounds in a flush fit magazine, are very close to the 5.7 in terms of ballistics and, by the way, cost half what an FN does. They also have excellent sights straight from the factory.

In fact, for what a 5.7 costs, you could nearly buy both the XDm and the Kel-Tec. The difference in intitial cost would be easily offset by the savings in ammo cost after one or two cases. The FN isn't an awful design, but it has its limitations, and unless you can get the penetrating rounds (ie, unless you are military or LE and are buying it as a specialty weapon) I consider it an expensive toy.
 
Re: FN 5.7 Thoughts?

Please read this article on the difference between defending against four versus two-legged threats. You'll notice the 5.7 is exactly what you don't want against animals.

Please note I don't necessarily agree with all caliber choices mentioned, and certainly not the bear spray recommendations, but the message is solid. For a pistol round against the "problem brown bear", I'd recommend the 475 Linebaugh.

Re: FN 5.7 Thoughts?

If you have a 45 already and it is a 1911 you might consider a 460 Rowland conversion from Clark Custom. Kit is a barrel, comp. and beefier springs for about $250-75. Buffalo Bore hard cast 255 gr at 1300fps and ME of 957ftlbs, putting it at about the middle of 44 magnum loads. Probably just in the realm of bear loads but definitely enough for anything smaller. I find it very manageable and 8 rounds in a platform that I do most of my handgun shooting with is a plus. In my hands it is far easier for me to put a handful of rounds on target where it counts than a 44 mag wheel gun. I have a 5.7 and it is a fun gun with a lot of capacity but not what I would want to be shooting at cougers or bears.
 
Re: FN 5.7 Thoughts?

I own a 5.7 w/ CMore sights. The trigger feels strange, & it takes getting used to. It's a fun gun to shoot. The recoil is minimal, & it has a 20-30 round mag. However, I wouldn't stake my life on it. I would carry my FNP-45 Competition (15 round 45). I would feel more confident on the terminal ballistics of the .45 vs 5.7. The trigger on the FNP45 is fine, but it doesn't compare to the match trigger on my HK Expert .45. I liked the 5.7 so much that I bought a PS90. The SS195 & SS197 rounds are the only ones immediately available, but elite ammunition makes some nice expensive custom rounds. I've read that the 5.7 pistol w/ C More sights is more accurate w/ the SS195 round.

What he said.

Its the one gun I HIGHLY suggest you test fire one before you buy one. I was hot to get one when they first hit the market. Fortunately for me a good friend had one in his shop to add a new sight rail with a few cases of ammo to burn up. It was the biggest let down of any new gun I have fired in my life. The gun itself is a small engineering marvel. The mags, bottom ejection and the general layout is great. The problem is the 5.7 round. If I buy a bullpup style rifle the Styer AUG is a LOT better gun and round IMHO. The 5.56 takes a lot of crap for stopping power (some deserving). The 5.7 only multiplies that by an X amount.

Its a neat toy and plinker but not something serious I would want to carry for defense or use on woods critters.
 
Re: FN 5.7 Thoughts?

Thanks for the input everyone. It sounds like the 5.7 round is not bringing the velocity needed to create a traumatic wound cavity that I thought it might, and at almost $1,000; I think I will just continue to carry the old trusty Glock 21.
 
Re: FN 5.7 Thoughts?

I have a SBR PS-90 that I stuck a 9mm can on. I dont care for the pistols.

Tough/tricky caliber to reload, but fun to shoot and easy to suppress.

Worthless on critters though.
 
Re: FN 5.7 Thoughts?

Its nothing but a fun-gun to me. I wouldnt use one for personal protection, mainly because I like a fullsize pistol.

The round is hot, but like others said, its a 9mm pretty much with a cool blue tip.

Blast to shoot, especially the PS90's with a Cmore red dot on the top, but ammo is too expensive, atleast in my area.
 
Re: FN 5.7 Thoughts?

I agree with the consensus that the 5.7 round isn't a great choice for animal protection. I think a Glock 20 with 17+1 capacity (with the +2 extension) is about the best choice out there. Loaded properly, you can hit over 800lb-ft, and you've got 18 of them on tap.

All that said, I don't think the 5.7 can be dismissed as quickly as many here have: I hope I don't stir up emotions with this analysis, but it does offer some real "evidence".

Consider the Fort Hood shooting. Nidal Hasan was using an FN 5.7 pistol, and he KILLED 13, wounded 30. That is a 30% kill percentage, performed with a pistol, which are notoriously non-lethal. (Jeff Cooper: "A pistol is only good for fighting your way back to a rifle"). Thank God more weren't killed. Personally, I believe the number killed would have been less if he had employed a 9mm pistol.

I've shot the 5.7 pistol, and I want one. I'm not an amazing pistol shooter, but when I borrowed my sister's boyfriends 5.7, I was amazed at how fast I could accurately deliver shots downrange. At 25 yards, I can hit a 3" circle 20 times out of 20 shots in less than 10 seconds. With my favorite pistol with which I have the most practice (Glock 30), I can hit a 6" circle at 25 yards 10/10 in 20 seconds.
 
Re: FN 5.7 Thoughts?

Ok your in the southwest I think we have a mix up in terminology a brown bear=grizzly. I'm reasonably sure there are no grizzly's south of Montana, central Idaho and Wyoming. Now blackies are quite a bit tamer and can sometimes be intimidated. I swatted one on the nose with a fly rod and he turned tail and ran BUT that's because I only had the fly rod. I would have preferred to give him a lead injection to the face with something that started with a .4

Either way I wouldn't want a 5.7 for any color bear.

I don't dismiss the round out of hand,
In regards to the FT Hood shooting I sat here and did the math compared to Tuscon where much of the distance and circumstance was similar and extrapolated that a 9mm would be nearly twice as deadly. In fairness to your analysis you lowballed the mortality it's above 40% you included the suspect/perpetrator. That jives with a couple studies I saw quoted on shooting voodoo that basically state if you are wounded by a firearm there's a 40% chance you will die, most times at the scene.

It took me several years to even develop an opinion on the 5.7 in pistols or the PDW, and I refused to pass judgement in it without firing it either. Now I am firmly entrenched in my belief that it is essentially a reloadable 22wmr. And whenever the question is posed "would you use a 5.7 for..." I refer to wheather or not I would use a 22wmr. The pistol itself is neat, but lacks many of the qualities that would recommend it for practical usage in defense against meaty targets. Unless you are fulfilling the first rule of a gunfight: and then there are plenty of better and less expensive ways.

For the OP if you already have a 45 that is suitable, as are magnum wheelguns I recall SW sells a DA revolver that holds 8 rds of 357 in very near the same price point as the 5.7.
 
Re: FN 5.7 Thoughts?

Yes , by brown bear I mean brown in color... not a grizzly. I guess I should have said cinnamon instead. I didn't realize that brown bear was used only to describe grizzlies. I know that black and cinnanom bears are for the most part not very aggressive. A problem bear is term that we use for bears that have gotten a taste for human food and have discovered that it is an easy meal, that can usually lead to aggressive behavior. Sorry for any confusion, I am no bear expert, but I do know we haven't had any grizzlies in our area for about the last 100 years.

 
Re: FN 5.7 Thoughts?

I have a Five-seveN. I like it but I wish now I'd have spent the same money on a couple more Glocks or another EBR.

The only reason it ever ended up as a handgun cartridge is FN decided there'd be a market for a sidearm in the same cartridge as their new PDW. It's an okay PDW round from a 10" barrel but from 4.8"? That's a whole 'nother kettle of fish.

The best way to defend against a bear with a Five-seveN is to hand it to him politely and pray that playing with it will distract him long enough for you to get to something with a larger hole in the end of the barrel.

...or rub your PS90 down with bacon and practice throwing it.

As I mentioned above it was a huge let down actually firing the 5.7. I went from "had to have one" to "I like my .357 lever gun a lot better now". I cant comment on the pistol version but for the cost Vs. what your getting I would rather have a couple of anything else.
 
Re: FN 5.7 Thoughts?

Maybe what we all missed here is that the Belgians designed a round for the sole purpose of stopping the French; without antagonizing anyone else by producing a useful cartridge.
 
Re: FN 5.7 Thoughts?

I think they are fun guns to shoot but for the price of the round there are a lot of other options. If it is just for plinking and a novelty go for it otherwise find something with a better round.

guntard007, I already was laughing hard from Grimm17's post but when I got to your fart story, I laughed so hard my diaphragm locked up and I couldn't make a sound. My family thought I was having a convulsion.
