    gonzav71,

    I wonder why in the world does Walther cakes up the internals with so much grease? That is beyond me. Even though this rifle is very easy to work on, not everybody wants to dismantle the air rifle.

    Paul,

    I hear you. The LGU Master Pro is heavy no doubt. I would not carry that in the woods. I have a PCP for that, but for HFT competitions and bench rest it is second to none. 

    As far as the chrono numbers, what you were told for performance is about right. Of course it depends on the pellet weight.  Mine with a .22 JSB Hades, which is a 15.89gr pellet I am getting around 680 fps with light grease on the spring. I have mine with more grease on the spring which slowed it down for more accuracy and it is tuned to 640 fps with the Hades. The Benjamin Discovery 14.3 they chrono at 725 fps. I have not shot a lighter pellet. I assume that the fps will go higher with the JSB 13.43 and even more with the H&N Barracuda 12.35.

    Keep in mind this air rifle will not blow the barn doors of its hinges when firing. It was never meant for that. However it can place the pellet exactly where you want it  if you do your part. I have taken squirrels with the LGU at 45 yards no problem…

    Hey Paul,

    I had a LGU Varmint that was rated at 800fps and when doing chrony testing had the following results from various pellets. Note that these results are from straight out of the box without any mods or cleaning.

    • Crossman Domed Ultra Magnum (14.3 grains): 693 fps

    • JSB Exact Jumbo (15.89 grains): 664 fps

    • AA Hunter (16 grains): 660 fps

    • H&N Baracuda Hunter Extreme (18.52 grains): 615 fps

    Regardless, the ft-lbs averaged 15.5 for all three pellets. Again, these results are straight out of the box and agree with what PianoGun was seeing.

    I'm assuming the 800fps are from something like the Predator GTOs.

    Overall I was impressed with the accuracy but not a fan of the stock when taking off hand shots so I sold it and bought the LGU Master also in 22 – I love it and don't mind the stock trigger for now.

    Hey Mike,

    The LGV / LGU Yankee trigger tune is easy, cheap and gives very good results. Do a  AGN search for “Yankee trigger tune” if interested.

    The concept of the modification with JB Weld and a screw is valid and I'm sure it works if you want to spend the time and have the skil-set to do it. I though about doing that, but then for $18 I bought the LGV /LGU trigger from Krale which is metal and has two adjustment screws to begin with with a finer screw thread adjustment. For me it was a no brainer

    That is a good price.  Looks like shipping adds $28?  And you can simply use a fine threaded grub screw for the added screw.  It can work very well and can be done in just a few hours.  Either way will work.

    I initially thought about machining a trigger first, but, the trigger from Krale worked great, and you are right about the shipping as it was $28. Still worth it to me as it is a solid metal trigger and I do not have to spend time fiddling with it.  I know that you need the finer thread adjustment as a 1/32 screw turn made the difference between a 1.5 to 1.2 lbs of trigger pull.  I bought the LGU and trigger at the same time from Krale so they did not charge me for shipping for the trigger.

    I've never really considered myself very good at tinkering but decided to buy the metal match trigger from Krale anyway.  I surprised myself just how easy it was to install!  I reviewed the article for the yankee trigger tune and positioned the screws to the recommended starting position (3.93mm for the front and 4.88mm for the rear).  After that the triggers were swapped in less than 10 minutes.  I stood there a little stunned so decided to check out the grease on the piston and spring while the gun was apart.  Piston had a very light coating which checked out and the spring seemed to have a little more than it should have so I decided to raid my daughter's painting supplies.  I found an old small brush and used it to remove a little grease off the spring.  Surprisingly simple overall.

    Afterwards I did a few test shots and the new trigger is definitely worth it.  I can feel that the trigger pull weight is less but I can't tell you exactly how much because I don't have the tool to measure it.  The other difference is that the second stage break just feels more crisp and clean.

    They will probably never be as good as the very best triggers but they can be made excellent with some work.  Glad you got it improved.

    Well it's been a year since I first bought the .22 LGU. Now I also bought a .177 . It is my go to for Field Target now. I designed a new competition trigger for it and it works very well.  I am thinking about selling it. I gave one to Hector Medina to try out. He ended up getting a wright up on it on his website /  blog.  I have a straight and a curved one. They can be adjusted down to 8oz if needed.

    Interesting work on the triggers.  Did you rearset the blade a bit on those?  If you decide to sell them, definitely list them here.  I might try a couple.  I have an LGU and an LGV competition ultra, both in .177 of course😁.

    Great I am glad to see interest in these triggers bandg. 

    The Walthers LGU, and LGV are such amazing air rifles, but they come with a horrible trigger from the factory. So I decided to do something about it.

    I am not a company, instead I do all the work at my home workshop. I do the cutting, polishing, and hard anodizing. It takes some time to make one trigger, but the results are well worth it. I tried the two stage OEM from Germany, but it did not do it for me. I wanted more performance. So I decided to come up with something better. Now with the new trigger It is so much easier to shoot my LGU . If I miss a target is either me, or the wind (which is still me…).

    The prices are: for the curved one is $70, and the competition semi- straight is $80. The curved one is a bit further back and a little longer. 

     

    This is Hector Medina's write up on this trigger:

    Here is a video on YouTube of testing the trigger pull:

    Again, nice work and interesting piece from HM.  I'll send you a PM and get information to try one of the curved, more setback units.

    Pianogun, I read Hector's write up on your trigger. I'd definitely want one. But first I need to get an LGV. I have a HW97kt that I haven't been totally happy with and would trade it for a LGV. Had I known about Walthers back when I bought my HW…. I gripe a bit about how HWs get so hyped up that other great guns get ignored. 

    I notice people wondering about the fps rating of the LGU/LGV. It needs to be mentioned that Walther made them with two different power levels. I think those were 16j and 23j. You need to know which power level your gun was manufactured for. I think the only difference is the spring.

    I have sold one trigger to a gentleman in Serbia that has an LGU Varmint. I did not know what to expect since I personally have not tried installing one in a Varmint. However he decided to take the risk knowing that he would be the first. I asked him to give me some feedback. He wrote to me through emails the following:

    "…Hello Eric. Trigger arrived today. Didn't test it yet but I will soon. It looks really good, feels good, color turned really good and the manual is probably the best I have seen in any product.. I will test it soon and will give feedback….. Trigger is amazing, super adjustable and really crisp when using the first and 3rd screw. It was adjusted really good out of the box but I adjusted it a little bit more for my liking….I forgot to mention that in order to fit in Varmint stock, you will have to grind the trigger guard a little bit. Trigger is touching insides of the trigger guard and it can be done with sandpaper like  remove 1-2mm. It will not destroy the trigger guard or make it weak just a little bit of sanding. I tried the rowan engineering one and nick murphy trigger ( which was considered as the best lgu trigger) but nothing beats this one. I think you should consider making these triggers for weihrauch, air arms, diana… This is truly an amazing trigger…"

    Naturally I appreciated his comments. That should give you an idea of what to expect if you decide to install one in your Varmint.

    Take care, 

    Eric
