The barrel would probably fly out and stab you in the forhead

It would be less mass on top and a higher percentage of the total weight would be on the bottom which I think would improve recoil.

Is there a polymer gun that has a polymer slide?

It actually works the other way.

A heavier gun and heavier slide have less recoil.

.45ACP 230+P is not a problem out of a short barrel on a Kimber Ultra. Snappy with the alloy frame, but manageable.
Likewise, the Glock 30 and 36... poly frame, .45... snappy, but they handle just fine.

Shoot a 357mag from a 12oz Ruger LCR or a Smith M&P340 and you'll never want to shoot that gun again.
You may not BE ABLE to shoot it for a few days.

What would be cool though, is a polymer frame with a metal slide!
You would get the weight reduction in the grip, yet keep the recoil reduction in the slide.
I think if someone could come up with a Very Polymer grip with 9 mm now that would be something!

Try a S&W 329PD.


It only weighs a pound and a half, practically no recoil on your planet.

You have to consider not just the overall mass and center of gravity of the gun, but also where the recoil direction is applied relative to the CG (determining how much the muzzle will want to rotate upwards, lower is generally better) and the reciprocating mass (determining how long of a duration the recoil impulse is spread out over, more reciprocating mass will generally slow things down and make the recoil impulse easier to manage.)

Metal frame polymer slide => Less recoil.
How about , metal frame, metal slide, polymer barrel => Less sound.
Hey,,,, I am a newbie alright !

Well it will improve recoil because you'll probably only get one shot out of it, before it cracks. So no second shot no recoil pretty simple really.

Negative.

Lighter slide with a heavy spring will not cycle properly.
You need the mass of the slide to carry the energy of the discharge to cycle.

There is a reason there are exactly zero polymer slides.
Closest you are going to get are some of the lightweight revolvers like the Ruger LCR and Smith Airweights.
The LCR has a polymer trigger housing/grip with an alloy frame.
The Smith Airweights are either aluminum alloy or an alloy with a small amount of Scandium.
Very light.
Very much recoil.

The ultimate example of "lighter slide with a heavy spring" is a revolver... the spring is so heavy that it does not even cycle.

A lighter slide and a harder (stronger) spring would both work to make the cycle of the gun faster, which would make the recoil impulse sharper/worse. Also, if you try to cycle too fast, the gun may have trouble ejecting and feeding reliably, and youíll be making it more picky as to what ammo it will run consistently.

Polymer slide would not create a very consistent lock up with the barrel. It would flex so much that I would be surprised that the round hit the same spot twice at benchrest. Secondarily all the heat from the barrel could melt the slide. It would be a decent idea if you tried carbon fiber instead of polymer. Would still have a bit of flex though.

The polymer is not strong enough to contain the pressure of a standard 9mm round. I’m thinking after a few rounds the locking lugs will rip. The light weight of the slide will not contain the pressure.

Probably be real exciting in 10mm.

The weight of the slide helps mitigate the recoil.

Even 5.7 has a steel core slide that is encased in polymer. It’s arguably the closest to polymer slide for a full size cartridge.

Recoil is not determined by percentage differences. It is the total i.e. 100% mass of the firearm. Of course there are other factors also.

That's funny because
I was thinking making an auto pistol with a slide made of a nicely checkered and figured walnut wood and the grips made out of a case colored blued steal.


... you know, to improve its classic looks.


PerkOne, I hope you know that we are all just joking with you.

But please keep thinking out of the box though.

Slide in polymer? The ring that hold the recoil spring assembly (shown in picture) will immediately break.

OP are you by chance an engineer, with multiple degree's? You may want to rethink the physics of your claim of less recoil from lighter materials.

My concern would be durability if it was dropped on carpet.
