3D Animation: How a Remington R51 works

The Remington R51 is a semi-automatic pistol announced in January 2014. The R51 is a modernized version of the John Pedersen-designed Remington Model 51 pistol chambered in 9mm (9×19mm Parabellum).
It uses a locking breech block within the slide utilizing the "hesitation-locked" action originally developed by John Pedersen.

"How an R51 is supposed to work"

[@quintussergius]

The fundamental problem with any pistol design from this period is stacking tolerances. They were designed to be assembled by master gunsmiths, not assembly lines.

Great work

Thank you!

Can u please make video on how israeli negev works

[@user-dx9ku6ni9o]

Nice

[@Deathunter761]

So it uses a blowback feature as the tilted bolt recoils into its recess, but later the recoil (or inertia) pushes the slide which unlocks the tilted bolt and allows the cycling, is that right ?
It's almost the same as Benelli B76 I think, using the counter action force not to move the barrel but the slide.

The original Remington UMC of ~1917-1926 with its hesitation action was reliable; this newer variation is not, though I don't know why.

I had problems with feeding procces,is not a great gun.I prefer a Walther PPK.

[@chinowitahwood]

did you end up fixing it ?

[@gamertardguardian1299]

First pistol ive seen where the slide doesnt lock when the last bullet is fired

[@GenScinmore]

Ruger lcp 380 doesn't either

[@SpawnofHastur]

The core design, the hesitation lock, is sound. Remington just fucked the dog real hard on the R51.
I really wish a company that actually knows what the fuck it's doing would give the mechanism another chance.

[@3DGunner]

I think the same. The design is really interesting. Maybe another company picks it up one day.

@@3DGunner I'm fascinated by the idea of a simple spring resistance for a delayed blowback pistol. (Not the complex springs of a roller-delayed system.) Does the R51 use the pressure of the magazine spring pressing the base of the case against the hesitation feature (tilting breech block?) to provide the spring pressure that delays the opening?
Love the 3D animation, it's super useful - and very well done!
