>gas-operated pistol with fixed barrel for easy suppression holding 23 rounds with red dot cut and pic rail for light
This has to be one of the most advanced handguns released recently.
>gas-operated pistol with fixed barrel for easy suppression holding 23 rounds with red dot cut and pic rail for light
The Boberg bullpup suffers from pulling apart cartridges. Bullets. This is only becuase the bullets are not bottleneck.
The 5.7 is bottleneck, and benefits from every inch of barrel it can get. The M&P gun is not advanced. The GrandPower K100 is more technologically advanced.
If we are getting free advertisement from M&P, M&P is getting free technical engineering advice from /k/.
Is it a specific load it doesn't like? My father bought one ages ago and we've never had a situation like that happen
5.7 cases have to be lubed to function properly. Not a fricking chance they'd work in a boberg
>5.7 cases have to be lubed to function properly
No they don't. That only applies to the P90s top loading magazine.
>The Boberg bullpup suffers from pulling apart cartridges. Bullets. This is only becuase the bullets are not bottleneck.
No it's because most ammo isn't crimped very tightly. Your post is mildly schizo.
daily reminder a keltec pmr 30 is functionally identical to any 5.7 meme gun while also holding 30 rounds as standard
>the hecking rimfire isnt reliable
this isn't 1910, its perfectly reliable if you buy good ammo
>5.7 is more effective that 22 mag!1!1!!
i'm sorry for your moronation
>Keltec "quality"
Look at that crispy plastic omg
Where's the threaded barrel?
That's like a mandatory minimum at this point.
I like Kel-Tec but I also know the difference.
You cannot mildly limp wrist it. It's not for small hands because of the pull from the curve of the hand. It's got a fireball that blinds in even the slightest dusk/dawn. It also has issues with other parts if you don't locktight it. It also feels like a weird gun to those who shoots with usual guns.
This is consistently proven wrong but you keep on keeping on mr smoothbrain.
It's good if you just ignore everything that's wrong and believe your proof which is.... "dude trust me"?
Yeah. 22 magnum has the same energy as 5.7... if you're comparing a 24 inch barrel to a 5 inch barrel. Stupid homosexual.
>keeps posting stock image because he refuses to put his money where is mouth is
I'll put my dick where your mouth is if you catch my drift hahahaa
>this isn't 1910, its perfectly reliable if you buy good ammo
Good ammo isn't going to magically make a rimmed cartridge feed properly. These kel-tec quad stacked mags don't fricking work. I have a CMR 30 and the second round in every magazine is a FTF.
Rimfire vs centerfire reliability was conveniently left out of your statement.
The case the M&P comes in is made of nicer plastic than that.
>fixed barrel
Is it really, though?
I thought it was rotating barrel, basically a PX4-like short recoil action with a gas piston assist to make up for the low recoil. Suppressor threads onto the outside of the gas chamber, not the barrel.
You're right. The point is it's a novel idea and not having to use boosters is big.
I'm not falling for the 5.7 astroturf.
5.7 is in the public domain. There's no such thing as "astroturfing" a free and open source cartridge.
>t. OP Shlomo Shekelsberg, CEO of 5.7 incorporated
main problem with 5.7 is the case deisgn it is in fact straight walled (non tapered) even tho ita bottleneck because of that it needs that polymer coating on it when it could have been designed to be slightly tapered to reduce friction (but then the p90 mag would need to be heavily redesigned)
Smith and Wesson confirmed that their gun runs fine with unlacquered cases. This is probably true for all other 5.7 guns too.
Taper doesn't really solve the problem; it means that a stuck case frees up completely as soon as you extract it a little, but that does basically nothing to prevent case ruptures from trying to extract while internal pressure is too high.
Look at all the existing moronic-blowback guns in various rifle calibers -- they all use tapered cases, but still had to take extra measures to address the problem.
>Schwarzlose machinegun (needed cartridge oiler, even though 8mm Mauser has ~0.04" body taper)
>CETME/G3 (needed fluted chamber, even though .308 Winchester has ~0.02" body taper)
>Pedersen rifle (needed waxed ammo, even though .276 Pedersen has ~0.06" body taper)
>This is probably true for all other 5.7 guns too
I doubt it.
The S&W is largely unique among 5.7 pistols in that the barrel and slide travel together, with no extraction of the cartridge, until the barrel unlocks and bottoms out in the cam track. This gives time for the pressure inside the case to drop. The P90 is simple blowback, and the FN pistol, and I believe all the other 5.7 pistols, use a moronic blowback action; in both cases, extraction begins immediately, while the pressure inside the cartridge is still high, pressing the brass into the chamber walls.
Every other blowback or moronic blowback system I'm aware of either operates at significantly lower pressures, uses a fluted chamber to "float" the case off the chamber with opposing gas pressure, or relies on lubricated ammo to allow the case to slide while under pressure; I believe that blowback and delayed blowback guns in 5.7x28 need the lacquer coating for the same reason.
You believe you believe you believe
You don't know shit though and you have 0 experience. Federal American eagle which was for the longest time the only other option for 5.7 doesn't have the bullshit dry lube powder coating you're crying about and it's never been an issue with the old 5.7only with the ridiculous p90 mags was it ever an issue. This is old old information and frankly it's embarrassing that for someone who types smarty pants facts you're actually so ignorant.
Federal/Fiocchi ammo does have the lacquer.
the gun the p90 is based on had a similar and simpler mag and used 9x19 and worked fine, p90 designers were just paranoid about it and as a result designed a moronic cartridge.
Boo hoo homie so what is this a p90 thread? No we want this shit in handguns, your point is moot, shut up and you sit down when you pee.
How is it better than the fn rdo 5.7?
Less recoil, costs substantially less, has a significantly better trigger.
>cartridge was designed to provide handgun AP capability
>can’t buy the AP ammo
What’s the point again?
I prefer its less gay brother
>All the same stuff
>Plus 30rnd capacity
>Way cheaper ammo
>Can get the ammo at Walmart
>shops at walmart
22tcm will rise again! Just you wait~~~!
>captcha: PDWS
Preach brother. The unbelievers will soon know the truth....
Seriously tho, If Stacatto or SIG chambered a gun in .22TCM, the fricking plebs would call it the GREATEST CARTRIDGE EVER CONCEIVED BY MAN.
>5.7
Don’t forget about me
Are any of these 5.7 pistols particularly better than the other?
I carry my M&P5.7 IWB. It’s pretty damn thin for being a gun that holds 22 centerfire rounds. And you can shoot it very fast with good accuracy
It’s extremely fun to shoot suppressed as well. All around one of my favorite guns in my collection
>gas-operated pistol with fixed barrel for easy suppression holding 23 rounds with red dot cut and pic rail for light
>but its in .22 magnum
rip
>but its actually like .22 WMR from a riiiiiiiiifle!!!!
im aware, still shit for anything bigger than a coyote.
>gets proven to be a moron
>comes back to samegay later in the thread
I am going to start calling this guy 22gaynum
>varmint round that doesn't penetrate the standard minimum 12" of gel
Meme gun for notrainings.
