I have one that does work. But it's P.08 dedicated. Meaning, it doesn't work on anything else but a P.08 (tricky fellers them Germans :rolleyes:).

Don,

I happened to have a "divine moment" and realized that a corner rounding end mill would do the job, and after spending half a day on searching different web sites I found one the closely resembles the original cut. It's a bit narrower than the slot, but this works perfectly as it allows me to widen the cut for chip clearance as I go.

Here, I think this is it -

Lots of off-topic stuff in those 3 pages too... :p

That may not be the right thread...I thought Dave went into the filing of the barrel in more detail...Maybe Dave can remember what thread it was...

As I following this thread I have to comment how impressed I am with the creativity and talent of so many of the forum members. Amazing! :thumbup:

I tried to make one similar to that, but after measuring several barrels I realized that the band diameters can be very different (especially if you include the P1). However, yours looks simple enough, and if it does work I might give it another try.

GT. I like your "Christmas in July" anology, and hope that Santa has brought you an AC unit to blow some North Pole air into your workshop and perhaps a couple of elves to help with your projects. TH PS: We expect a heat index of 106F here in the St.Charles area today.

If you are looking for a sight blade with a flat or square top for a better sight picture and fits that dovetail, I think you will find that P.38 blades will fill that need. Of course you should open up the rear V-notch to match, but I am sure you will find that to be a better sight combination. Since you are using non-standard barrels, changing the rear sight notch seems appropriate.

Work it does. But as it fits the P.08 barrel band like a glove, It won't fit a P38, or even other Lugers other than the standard P.08, such as LP.08; 1904 Navy; or any .30 caliber.

Pictures make better examples. You can appreciate how it fits snugly.

Rather than clutter GT's bbl thread with sight pushers, why not someone start a new one.

It is worth while, and there are many different dedicated sight pushers, and some universal ones.

They do have to "fit" the barrel and the sight!

Kurusu,
just a hint for your pictures, when you are preparing them for posting, try reducing the color "saturation", it will get rid of the green ghosts! ;)

A sight adjustment tool (pusher) example thread for photos is a great idea. Will one of you guys please start one! If we get a bunch of examples we can make it a Sticky thread for reference.

crappy pictures taken after class tonight and I had my Christmas package from GT!

Sorry Don, sometimes you're lucky to get pictures :evilgrin:

VERY nice Ed!! With that amount of weight up front, the barrel rise when shooting should be minimal.

muzzle flip
 

Hi Doc & Ed, I did notice with the 6" barrel at near full mass, it soaked up a considerable amount of recoil as well... I really don't think an 8" barrel in that configuration would work?... More worried about closing then malfunctions?.... :eek:... 6" smooth as glass... best to all, til....lat'r....GT......:jumper:

Unless you're intended on rapid fire (10" or less), muzzle flip is kind of irrelevant.

Just my 2 cents.

It wouldn't hurt to try an 8", if it doesn't work you can just cut it off and redo the cuts up front.

Ed,
I like it; well both of them.

I'm going to get GT's 5" model and go with that; couldn't decide if 4 or 6 was better!

An 8" bull/slab is likely to be too heavy for the standard mainspring,would likely to go lighter.

Ed, your 6" bull bbl is approx 2 oz. heavier than an artillery 8" bbl., and close to what a 12" carbine bbl would weigh by my estimate; and about the max weight that would work reliably without monkeying with the spring.

The Art. mainsprings I've measured by my method are 14-16 lbs, and the 4" measures 18-20 lbs.; i.e. he heavier bbl requires a lighter mainspring as observed. It is impossible to predict what is in any given pistol, due to the natural variation and years of potential changes. The higher velocity from the longer barrel helps some also.

I also proved this to my satisfaction in working on a 12" .30 cal bbl, and getting it to a weight that would function.


Bottom line- if it works - super!!!;) The 6" pistol looks great with those grips too.

Just a teaser, at Rich's instigation/idea, GT and I are going to work on an adjustable rear sight to be added to the rear toggle- wish us luck!

The 5" bull slab barrel arrived yesterday, actually it is 5.3" long and weighs 9.8 oz.

That weight is 2.1 oz heavier than an artillery bbl with sight; but the balance is much closer to the hand- I can't wait to shoot it.

I installed it on a receiver and put it together to shoot in a day or two.

Pictures below. Looks super, nice work GT and Ollie.:cheers:

I do like a 5 inch - its a good all around barrel

Sweet looking gun :)

Another gts/t-6
 

I received my GTS/T-6 from GT yesterday. I was very impressed with the quality of workmanship. The point of aim feel for both single right hand and two hand grip is not too different than my Hi-Standard bull barrel target models.

I manually fed several snap cap rounds through the pistol, very smooth. I look forward to getting to the range and putting a few boxes through it. I plan to play with it a while and then put a rust blue and straw finish on my GTS/T-6.

I have to say that the 5in. bbl is my favorite length. I have a J. Dewey 5in. bbl on one of my Lugers, and the looks and balance is just perfect to my way of thinking. GT is producing some handsome barrels, that look quite nice on these "target" Lugers. I await some range accuracy tests.

Back from the range today, the bbl. functioned perfectly on my shooter frame.
Shot both WWB ball and some hollow points, both fed fine.

I didn't fire for accuracy, as I need to work on the sights to be able to see them a little or even a lot better. The fine luger sights don't work well on a black bull with old eyes and sunglasses!

But that is for another day.

Nice work GT. The 5" soaks up what little recoil there is and is a pleasure to shoot.

Dick and Don -

What mainspring did you two use with your G.T. 'bull' barrels??? By that I mean what wire diameter and how many coils???

(Saying 9mm or 30 cal is pretty much meaningless these days - too many possibilities of mainspring swaps, clipped coils, Wolff springs, Sarco [Ha!] springs etc)...

Rich,
I'll have to open the frame up and measure and count.

I used the frame I had been shooting the 12" .30 cal on, clipped spring with about 14 lbs. pressure as I measure it.

Very similar to what I find in an un-molested artillery, but weaker than the "normal" 18-20 lbs I see in a 4".

As you say, just too many variables; add to that old springs vs. new springs; loose fit toggle/slide vs tight one, and one just has to try it out.

I am convinced that the 9mm is more forgiving of spring differences than the .30.

Helped a lot, didn't I. ;)

You pointed out a very neglected area - tight rails. I've had to lap two Lugers to eliminate binding, and just last week I had the same annoyance with two Sarco slides on 80% steel frames. On one, I actually had to use valve grinding compound - very coarse stuff, and required both rubbing compound and polishing compound afterwards to get it smooth again. Now it's like slipping on soap in the bathtub! :D

There was a forum member here about a year or so ago who wanted his Luger barrel worked on. I did the work, but couldn't test it because his barrel extension bound up on my 1939 Mauser frame. :(

Yes,
they didn't number the pieces just for the heck of it.;)

Mainspring Details
 

Howdy Richard,

Previously posted by GT.

"GT's Range Test
Well, just got back for the range where I tested qty. 2 of the new GTS/T-6 & qty. 1 of the GTS/T-4 versions... They all worked flawlessly on my byf test frame!!!! ... Yeah Team!!... Now, I did have an owners frame for one of the 6 inch versions, and, with that frame, it wouldn't always close?... So, I swapped out the mainspring, original DWM, with the longer, and seemingly stronger Mauser spring out of my test byf, and problem solved.... All good!"

I have not had the time to shoot my Navy GTS/T-6. My local range has been flooded. Nor have I had the time to take down the pistol to count mainspring coils or mic the wire diameter. Until I get to strip the Navy GTS/T-6 I hope GT's comments help.

Have a most excellent day,
Dick

Mainspring....
 

On testing all, I used a standard WW2 Mauser 22 coil byf 9mm factory spring... It had about 4K rounds on it, and when I range tested Dick H.'s GTS/T-6, I ended up installing that exact spring in his frame, as I knew it worked with all the others, and it work with his as well.... (prior to that it wouldn't always close completely... It's a real balancing act when the barrels get fat!?.... ;)... Best to all, til....lat'r..... GT

Rich,
the .30 12 inch bbl/frame has a spring of 0.0565 diameter and 17 coils.

I just changed the 5" bull to a different frame and will test fire it next week, and count/measure and report!
