Walther LGU models?

Right Cant said:
I got my lgu a couple of months ago and.i noticed from the off it had a very slow and bouncy shot cycle even with 7 grain pellets, upon investigation it had a 2.6mm transfer port, a bit of research later and i opened it up to 3.2. Its a different gun now, it definitely feels happier and the shot cycle is loads faster.

How do you open up the transfer port
 
AFAIK LGV & LGU with 2.6 mm TP got only to the power restricted German 7.5 Joule / 5.5 fpe market.
Maybe early models were sold in other regions too but I have no proof.

The 6 mm LGU TP is one solid piece with the rather soft steel (not case hardened) compression tube and as written before here by others can be opened easily with some qualitity tools and basic technical understanding awa a miniscule chamfer on both ends.
The 25 mm LGV TP in my eyes is another league and I wouldn't touch it with my rather basic tools but leave it to a professional with a lathe.

Could I just ask the question, if you increase the transfer port size to 3.2 mm does that mean the swept volume goes down and the power goes down? I have heard mentioned that Walther’s are better around the 10- 10.5 ft/lb. Is there any truth in this

The power on mine went up by 0.5lbft when i opened up the transfer port. Im running at just over 11 now and might drop it a bit more when its settled down.

As Right Cant said.
Swept volume of piston (25 x 88) will stay the same but static compression ratio SCR (calculated with the swept volume of the TP) will change and thus SCR.

Sub12fpe and TP 2.6 mm (SCR 1017) means to much restriction to compressed air flow.
Much better TP 3.2 (SCR 865) up to 3.4 (SCR 766) - don't go over otherwise shot cycle with lighter pellets gets smashy.

Compared to a HW97 (26 x 80) and nearly same figures of the TP (6 x 3.3) shows a SCR of 838.

Have fun.

I’m going to take out the comp tube in the new LGU Black I bought and check it out. Did Walther ship any for the UK with the already 3.2mm transfer port?

About some 10 years ago Brian Samson & Co. completely wrote off the Walther LGV after a cheerfull begin. Because of the talk everyone dumped his Walther and shops had trouble to get rid of their stock.
At a certain point you almost got one for free when you bought ten tins of pellets.
Never believed in his words, but kept belief in that superb design.
Nowadays LGU and LGV are very rare, hard to find and when they go, they do big money.
I still wonder where all that Walthers have gone...

I know this is an old post, but I've just noticed it while searching for something and I can't let that go unchallenged.

I have an LGV Competition Ultra and I've had it since they first came out, I believe I was the first person to write a review of one.
I had and still have nothing but praise for the LGV. I have the Competition Ultra stock, but I actually preferred the Master stock which came out later.

I was one of the voices urging Walther to bring out an underlever version (which later came out as an LGU). I really liked the LGU as well, although I don't have one in my collection and I was gutted to hear they had stopped making them.

I have no idea where you got this idea from that I 'wrote them off' - but it couldn't be further from the truth.

I do remember being one of the voices defending the LGV and LGU though and I can remember why the LGV didn't sell as well as it should have done and that was because they released the Competition Ultra version first and it came with (at the time) quite a hefty price tag that put a lot of buyers off. It was certainly nothing to do with me or anything I've ever said or written about them!

Next time - before slagging someone off - trying doing some research first eh?

Well said, people should get the facts right.

That’s a beautiful Varmint if I’m not mistaken, and is it tuned by Nick Simmons. Is that his sticker

It's not nick Simmons it's a Tony leach sleeved down 22mm conversion and Tony sorted the trigger out as well, fitted with a rowan adjustable trigger (it's as good as any rekord or CD trigger), it shoots amazing and very accurate with .177 baracuda 8's.
