Brilliant design

I'm watching this brilliant design for some time already.

I hope, orders will be accepted soon. I've signed up for the mail list that will announce production (on http://www.bobergengineering.com website). I was extremely pleased to notice the attitude of the author of the design and owner of the company Mr. A. Boberg: the product is being put through a lot of testing. I'm sure we all will be pleased with the reliability of the gun.

I still have one question. Sorry if it has been answered earlier and I missed it. What is the drill in a case misfire? If there is click instead of bang, do I: drop the mag, work the slide, insert the mag...? What is the right procedure?

Again, I do believe in the reliability of this gun. I liked the part I read related to limp wristing (which becomes more of concern the lighter the gun is): not only the gun works perfectly, but also no one ever called limp wristing an "operator error". This is what I was pleased with. As in my humble opinion there is no such thing as operator error (except for loading cartridges backwards): no matter what the operator of the gun does: limp wrists, or falls from third floor, or is being pushed into snow drift, when he/she presses the trigger the gun should shoot (and reload if it is autoloader)...

Happy New Year everybody!

Since the stock trigger force is at 5.75 lbs, I have experienced misfires with one type of Russian ball ammo - apparantly, the hardness of these primers seems to vary. If you pull the trigger a second time, it will go off every time. I have not had an issue with other brands, including Sellier and Bellot, which is know for hard primers. We will be offering an optional 8.5 lb trigger spring that will deal with some of these less expensive types of target ammo.

I am just speculating, but I remember Rohrbaugh at 6.5 lbs, and now listed at 11 pounds - I am wondering if they went through the same thing.

FYI - the Boberg XR9 does not use an intertial firing pin - the hammer makes direct contact to the primer through the firing pin, so we are able to transfer more energy to the primer than other brands using the same trigger force.
 
Yes, I got that, thanks.

But suppose I'm an idiot, and loaded dummy which never goes off, how do I remove that from the chamber? In other words, if I understand the design operation: the claw drops down ready to pull next cartridge from the magazine after loading the previous one. If firing event never happens what pulls the dead cartridge out of the chamber when I work the slide? I probably miss something in the design and there is something still engaged with the cartridge groove that will pull the cartridge together with the movement of the slide? Or there is some different procedure to remove dead cartridge from the chamber?

Thanks for the lightning quick answer! And good luck on working out all necessary for the production!

What is not shown in the somewhat-famous computer animation is that the XR9 has an ordinary extractor that pulls the empty case (or live round) out of the chamber. The two tongs, that are below the extractor, transfer the live round to the extractor. So if you want to clear a dud, just pull the slide back all the way and let go.
 
The barrel material is a high-strength, high-toughness stainless steel. We looked at 410 SS and 416 SS, but opted for a tougher, stronger but more expensive stainless steel for our barrels. A good gun starts with a good barrel. I could tell you the exact material, but then our competitors might jump on the bandwagon and figure out the extensive process required to make barrels out of this material.
 
Thanks, this is enough information.

I'm sure, general public (myself included) will not understand it deeper even if you give more detail. But this is sufficient to know to realize that the product in flesh is (well, will be:)) as good as the design itself!

Tanks again, and best of luck releasing the product! I'll sign up for getting one as soon at you will open the sign up list.

Do you think you will get it certified to sell in California? I would surely be very interested.
 
A friend of mine recently showed me an iphone app featuring your Xr9 prototype... with the chamber too far forward, not sure who's responsible, but it also has a full auto closed bolt micro uzi, tsk tsk.
 
Mr. Boberg, are the production guns going to look like the pictures we've seen, with "Boberg XR9S" on each side of the slide, and without a "read manual" warning stamped on the frame? And will the caliber designation be stamped on the outside of the chamber?

Also, should I assume it's a coincidence that there appears to be a gap between the X and the R? ;)
 
Wow! Where did you see "read manual" on the frame? Is it really there?!

Well, I frankly would prefer instead of "read manual" something like "government warning: this gun may seriously damage your health..." ... or somebody's else health...

The only thing I noticed is that the magazine lips seem to be on the wrong side: as for regular loading design, for which cartridges are pushed out of magazine forwards. For this unique design they should be on the other side, or: the top line of the magazine shouldn't be parallel to the bottom plate, but slanted other way around... but that may be just a picture of "generic" magazine, I assume, not the one that comes with this gun, sort of "placeholder" for a moment of the development of website. Or maybe I'm wrong, and the shape of the magazine is so nontrivial, the it IS real magazine for this design.
 
No, no... I'm saying that in the pictures I've seen, there isn't a warning on the gun, and the caliber isn't stamped on the barrel, unlike almost every other production gun out there. I'd be thrilled if that was the case, as it would make a very sleek looking gun. Just smooth metal and "Boberg XR9S" shining out from either side.
 
Ah... that's a relief. Apparently I misread your post and should apologize for my sarcastic one... As a matter of fact I too would prefer as little engraved on the gun as possible: this is way different aesthetically, and I'm ready to pay a bit extra to opt for no engravings except for serial number, Bobergarms logo on the grip, and what is required by the law (which may be everything what usually is there :().

It is a good looking pistol. An excellent job in the looks department.

I would most want glock 17 ballistics with a shorter OAL. But I realize that most people just want the smallest pistol. Not me, as I like more velocity and more sight radius. But fine, there can be a second model after the most popular one launches.

One minor critique - don't like the term stopping power. One could just say 25% more muzzle energy.
 
About the pull-push feed for bullpup rifle

<b>About the pull-push feed for bull-pup rifle...</b>
It wouldn't be practical, as you still need to leave some space behind the bolt carrier in order for it to recoil. For the Boberg pistol discussed here, that space is simply thin air behind the slide, so it makes sense.

I really like the feed solution, and I think there is a real road opener, not only for compact pocket pistols, but also for full-size service pistols that chamber cartridges that need longer barrels (6-7") in order to burn the powder efficiently - namely bottle-necked cartridges like 9x19 (Russian AP load), 7.62x25(Czech/Serbian load), .357 SIG, 5.7x28, 4.6x30. But I think that the locking system would need to be completely redesigned for the first three, as a single lug would not be enough to contain the forces exerted during firing by large pressures acting upon a relatively large surface (case head).

If I were in the US I would certainly buy it. Where I live, gun laws are so restrictive you can't even buy a BB gun without police registration. Damn commies probably fear that we'll shoot them all, as they still hold on to the top jobs ;)

Actually, there is space right behind the magazine on the Kel-Tec RFB (see link below) to house the Boberg XR (tm) feeding mechanism. The barrel would then go over the magazine making the rifle about 3" shorter. The recoil springs would have to be mounted along the side.

Currently, the XR9 pistols have two locking lugs, with .250" of locking distance. For a rifle, we would probably go to three lugs but have them at a larger diameter to increase the surface area. The configuration of the locking lugs on a proposed Boberg rifle has little effect on the feeding mechanism.

Correct. Photos on site as of yesterday: http://www.bobergarms.com/photo/albums/magazine-loading

Note absence of magazine follower - an unnecessary part.

We have been revising the model numbers a little bit in addition to the engraving on the slide. I will try to get a CAD image of the new engraving on the slide posted on the BobergArms website.

As far as I know, we are not required to put "read owner's manual" anywhere on the gun. I think it is only for "Your honor, the plaintiff should have read the directions clearly engraved on the gun..." We are required to put our company name and address on there somewhere - we were thinking inside the gun.

As far as caliber designation - that is currently up in the air. We don't want to weaken the barrel at all (especially the chamber area where the pressure is the highest). Sure, an engraved chamber may survive a proof test, but what about thousands of rounds? Could chamber engravings have contributed to KBs in the past? I was left partially- stranded on a broken bicycle in SoCal in 1991 because my crank arm broke off. It sheared off right where the manufacturer had stamped its emblem (I did pedal back with one leg, which was about 20 miles). The replacement crank arm had the emblem silk-screened on there. I guess they learned their lesson.
 
Incredible design, great job.

How do I get on a pre-order list?
