Grand Power Pistols Coming Soon - Canadian Distribution

[renuguner]

Thanks for your interest, Canuck223.
I took some pictures and edited some arrows on them only to notice at the bottom of the page: "Posting Rules: You may not post attachments".
I will probably attach the pictures plus what I have written here, to an email to Grand Power eu, and see what they say.

All I can tell you, without the pictures is: the trigger transfer bar if part number 22 in this exploded diagram..
http://handguns.g00net.org/Grand_Pow..._K100_schm.htm
..and the two disconnector arms are part of it, and they reach up. And you can see the top of one disconnector arm peeping above the top of the frame in this picture..

Now locate the cutouts on the on both undersides of the slide for the slide stop catches (part number 8).

During reassembly,as you push down on the slide, it is possible to get the slide-stop cutouts to come down behind the tops of the disconnector arms, jamming the slide to the rear.

It induce the error, push down and pull back simultaneously, on the slide.

The solution is to push the tops of the disconnector arms down until they click, before you relace the slide. Then there is no way you can create the jam, regardless whether you pull back or push forward as you push down on the slide as you install it.

An afterthought:
I have here a CZ-83 and a Bersa Thunder 22, and on both the slide is removed and installed in the same was as the K100, by tilting the slide up and down. The CZ-82 even has the trigger guard you pull down to allow the slide to pass fully to the rear like the K100.
They both have a single disconnector arm not double like the K100, which doesn't change the relevance to the issue. In both the CZ and the Bersa the top of the single disconnector arm is well under a flat uncut part of the slide rail. And the disconnector arm is unambiguously pushed down by the slide, when you push it down.

The problem with the K100 is the position of disconnector arms in the frame, overlaps the position of the cutouts in the slide rail for the slide stop catches, when you line up slide and frame during reassembly.

Do me a favour. Try assembling your gun like I mentioned, with the slide upside down in your hand and the barrel right up at the front. Install the frame onto the slide (As in the frame will be upside down and pressed into the slide). Let me know if you can make it hang up that way. I know I can't.

Canuck223: Do me a favour. Try assembling your gun like I mentioned.

renuguner: Not having frame and slide configured in the recommended way, induces a different problem. The problem I am describing is another independent problem, and I don't think you understand the specifics of that problem - probably due to lack of pictures. Never mind. Thanks for your interest anyways.

The translucent model was simply for show. They are working on the development of the .40 and .45 models and we should see them in production by the end of the year. I will keep everyone updated as to the progress.

At this time it appears the first order will contain the X-Calibur, the K100 Mk7/1 Basic, the K100, the K100 Dynamic, and the K22S. We will also see magazines and other accessories such as fiber optic and tritium sights, larger magazine releases, and the larger safety release when it reaches production. Spare parts will also be in stock for all pistols hitting the country.

Best regards,
Ryan

Can you tell me whats the different between the K100 Mk7/1 Basic, K100 and the K100 Dynamic.

thx

I have the first gen K100 with lots of rounds through it and your problem is a first. Perhaps your version is different from mine.

To replace the slide on the K100, it has to be pushed fully back so the slots in the slide allow it to drop down into its correct position. Against the return spring pressure, this can be awkward, especially if your hands are oily. ( I had it slip out of my grip and broke the plastic front sight on the basement floor).

Try assembling the slide and frame without the barrel and spring. You will see that once the slide is almost all the way back, it drops right down into position without any interference from other components.

If this works for you, try it again with the barrel and spring and see what happens!

The terms sometimes evolve.

The K100 Dynamic usually has a very nice wide serrated rear sight (adjustable side to side) and the fiber optic front sight. It also used to come with the large mag release button. I upgraded my STI GP6 with these parts.

The K100 Mk7 is the new standard model. The principal difference between it and the older Mk6 is the new backstraps. The Mk7 has 4 different backstrap options. Aside from that, the serial number plate I believe has been moved to the bottom of the dust cover.

Thank you very much

Just wanna throw this question out there. If you change your stock barrel to a longer barrel (3/4") more. Does it make a huge different? And Do you need to change a different sight? Cause the barrel is longer.

The added barrel length isn't a bad thing. The added weight can tame some recoil. Thing is, it's somewhat of a half measure. In general terms, you want the front and rear sights to be as far apart as possible.

The front sight would probably not need to be changed.
