New Kel-Tec PMR-30 auto pistol

I think the members of THR need a refresher course on what a troll actually is.


A troll is:
Someone who intentionally makes a false statement with humor being his main motivation.
i.e. someone posts a picture of bruce lee and someone posts "OMG I loved him in Hero."

A troll is not:
Someone who is ignorant of the fact that no one likes or agrees with them, and /or becomes defensive about it.


DISLAIMER: my post is not talking about anyone specific

Your definition is too narrow. There is more than one type of troll. Gunkid was a troll's troll and he didn't fit the definition you gave.

Anyway to get back on topic

I keep looking at the sights and can't tell if they adjust. Any info on these from anyone?

front sight is dovetailed, so it is windage adjustable by nature. It could possibly be swapped with a different height sight, to adjust elevation.

rear sight looks to be fixed.

Wow
I want two and I usually only care for revolvers. I'm a little concerned with breakage of the front sight, other than that I find it pretty sexy. Best of all its lefty friendly!!!

I am not sure about the pistol but I think I would love the carbine version. That thing looks sweet.

Oleg, you are truly my hero. Gorgeous!

I got to shoot this bad boy: DAYUM!! VERY accurate,0 recoil,balance nice.Trigger is VERY light;maybe too light but crisp with very short positive reset.I observed others have failures to extract:I did not & bear in mind this is not the production model.Initially I wasn't crazy about the 'HiViz' sights but after shooting it I'm converted. I'll be interested in seeing how KelTec does the mags:seems like 30 rounds'll but a lot of pressure on the spring & floorplate.
I can't say I'll be first in line if & when they hit the market but that's me:I tend to let other folks wring 'em out before I buy anything,but this rascal shows yea-much potential.
Overall impression quite favorable.

In all these years, I've never had a floorplate bulge or come off of any of my P-30/R-31 mags, and I have several... and KT/GK have come quite far since the Grendel days. I don't think it'll be an issue at all, personally.

The Military uses a .223 round which is .22 caliber. Don't sell that .22 mag short as a viable defensive round. Kel-Tec is definitely on to something here.

I took down a 40 lb bore with one shot at 100 yards with one!

Was this a boring midget at a big party or a wild pig?

(OK, the current correct term is 'small person'...)

There's a big difference in shooting a .22 mag out of a rifle as opposed to a 4.3" barrel.

Yes and this especially true of the 22m because of the slow burning powder used in this cartridge.

my 22 mag pistol has a 6 1/2 inch barrel and achieves about 1,400 fps range i know rifle barrels do it better justice.

Uh yeah. A 40 gr bullet at 1250 fps is not the same as 62 gr bullet going 3100 fps. Little bit of difference there.

You can get an AMT automag stainless steel tank for right around $300, there is about 0 demand for a 22 mag semiauto, now if it were 22lr with a 30 round internal magazine now we'd be talking.

Wanna bet? They will sell a ton of them.

I don't see an AMT as being an alternative. It is too heavy, has no rail, and looks less like a 5-7 pistol.

Faster burning powder does not make a bullet go faster from a shorter barrel than a slower burning powder *

Whatever powder will make a 40 grain .22 magnum go the fastest in a 4 inch barrel will likely be the same powder that will make it go the fastest in a 16 inch barrel.

The reason to use a slower burning powder is to keep from exceeding max chamber pressure. Burn speed is thus based on bullet mass and pressure, and not much based on barrel length. I am not saying ammo designers don't pick slower powders simply because of longer barrels, but if they do they are using a hard-to-kill myth rather than fact. Peak pressure is usually reached before two inches so only on *really* short barrels is there much difference.


*assuming both are loaded to max SAAMI chamber pressure and as long as the 'short' barrel is not super short.

I really don't know that much about fast and slow burning powders but it seems to me that in the case of a short barreled gun a cartridge with slow burning powder will have used less of the powder while the bullet is still in the barrel than a cartridge with faster burning powder.

Wouldn't it be like in a hundred yard drag race pushing the gas pedal halfway down vs jamming it to the floor?

You could get to sixty mph at half throttle but would need more distance to do it vs flooring the gas.

I might wrong but this seems logical to me.

You are right. However, in your example, the fast burning powder is the one which will give the maximum velocity in either barrel. So why is the 'slow' powder in your example under consideration? What would it do better than the 'fast' powder?

It's not! My thinking is that the fast burning powder is what I would want in a 22WMR pistol.

your analogy is correct, BUT, only if you remember that there is a limited amount of powder to burn in a cartridge. whether it is slow or fast burning doesn't matter, you can still only cram so much into a cartridge. So in your analogy, assume both drag racers only have enough fuel for 5 seconds of full throttle (or 10 seconds of half throttle, or 20 seconds at 1/4,...).

now, would it be faster for you to burn 5 seconds of full throttle, or 10 seconds of half throttle. And what about if one drag car weighs half of the other?

I think your missing the point. What I'm trying to say is that the 22wmr is meant to be a rifle (long barrel) cartridge and when you fire it from a pistol with a much shorter barrel than a rifle and the powder is slow burning, the bullet might be gone and out of the barrel before all the powder has burned.

With faster burning powder more of the powder will have burned before the bullet leaves the barrel, therefore reaching a higher velocity in the shorter pistol barrel.
