    I've been thinking about getting one. I have a Beeman HW97k so maybe it's totally unnecessary. I don't get to shoot my other springers enough as it is.

    I have a very nice HW97 KTS .177 rifle.  Shoots good and is a very nice gun.  My LGU is better.  YMMV.

    10 AA 8.44's @ 40 yds.

    I installed a longer trigger screw and polished the stock and thats about it. I've thought about an HW97…but just can't justify it. Maybe in .22?

    Sure do love this Walther!

    In my case, better in that it is first shot accurate every time and just seems smoother to me.  The HW97 is a great gun and the trigger is better, even with the extensive work on the LGU.  The Walther trigger is now very very good but the HW97 is about as good as they get in that regard.  Still, the Walther just shoots better for me day in and day out.  Personally I believe it is in large part the weight but not 100% sure.

    Love all spring guns. Just wish they all had HW77 or micro click buck horn sights. Something fun & quick acquisition

    The trigger on the LGU is poor in that the pull can't be adjusted to a light touch like on my other spring guns.

    I modified it by moving the second stage screw further away from the trigger's pivot point.  That fixed it.

    I also added a metal shroud around the spring in the piston to further dampen the spring.

    You would not be disappointed as an LGU owner.  It is easily on par with my TX200 and HW97 in accuracy and sometimes even better.

    The gun is a sleeper that never gets the attention it deserves.

    Since you have so many you should donate one to the "needy"  :)

    I don’t have the LGU, but do have 2 LGVs. .177/.22 except for the fixed barrel part of it, they are very similar. My .22 is in stock condition with the .177 heavily modded. Don’t think I did a good job on the trigger though. They are very accurate out to 30. 

    You are more than welcome to come by & shoot them if you like.

    I have an LGU – 12 FPE version. I have custom stock on it. I replaced the trigger with a Rowan Engineering one.

    It shoots better than the HW97K I used to own and much easier to work on.

    .   i replaced the trigger on my .177 lgv ultra back in 2014 with the metal walther trigger with two adjustment screws on sale at pyramyd at the time.  actually, and i'm not trying to start a different topic on this thread here, but hector medina's website had a better way to modify that trigger.  the metal one was grinding where the adjustment screws touch the insides of the trigger or sear .  the metal one felt better at first, but i found his little remedy a much smoother trigger.  once you get these high quality walther air rifles apart, you'll notice that the air chamber is sized down inside by a sleeve or insert.  i immediately contacted steve pope to see if he had a tune kit for these, but he had no plans for that then.  when i see the 800 fps velocity rating on the .22 lgu varmint version, i assumed that walther pulled that reducer and used a larger piston/seal inside.   but after further research, i find that the varmint lgu doesnt have any more power than the 650 fps walther lgu standard version.  my .177 lgv master pro is grouping well even at 60 yards on non-windy days (1/2") , which is amazing for a gun that has about 400 shots on it.   but crap, it's like an 11 lb gun scoped.   still better than the cheesy plastic stock i had on my lgv ultra, tho.  i couldnt believe how hollow that synth stock was compared to the rest of the gun (and for that price).  – paul.

    John,

    My custom stock was purchased from Field Target Shop (website same name) from Lithuania. I think they are not taking any more orders until they sell the left handed versions first.

    Very Nice stock Leo!!

    This is mine, and I love it. LGU Master Pro

     

    I had to do some modifications. Because I wanted more out of it, but now it is fantastic. In an indoor range (no wind), it produced a 1.7 inch group at 80 yards, and at 20 yards literally stacks pelleted (0.18" groups).  From 18 to 28 yards is pretty much a straight laser beam. The zero is at 25 yards and the latitude POI variation in the 18 to 28 yards range is only 0.25"). 

     

    The mods I did are:

    -Trigger was changed to the metal one (from Krale) with two screws. 

    -Replaced the first stage screw with a longer one then rounded, thermally hardened, and polished the contact tip to a mirror finish

    -Polished all sears and contacts in the trigger group and lubed all points of contact with moly

    -Shortened the return/reset spring on the trigger(removed 2 coils) to offer a more prominent and faster trigger reset)

    -Tapped the back of the trigger guard and added a back stop screw to reduce trigger travel

    -Trigger set to 1.2 lbs, with zero creep, and crisp let off and brake ( I could set the trigger to a lighter pull, but I felt that it was a safer decision to leave it at 1.2lbs)

    -Enlarged the transfer port from 2.6 to 3.0 mm (reducing the firing impulse)

    -Removed and cleaned the factory caked up grease on the piston and in the transfer port (it was detonating and dieseling see original factory condition pic below) 

    -Added non combustible Krytox lube around the piston seal and a mix of Walther molybdenum, and marine gear grease on the spring (to remove the barely noticeable spring twang)

    -Added a 2mm washer in between the base of the plastic spring guide and the spring in order to add a slight spring pre-load (slight power increase 30 fps)

    -Added an anti slip grip on the sides (you can see in the pic above)

     

    In all fairness the air rifle was shooting very well from the factory. I did not like the plastic trigger it came with, and of course the dieseling. You do not have to do the modifications, I just wanted to push the rifle to the next level of performance.

    At a minimum, every LGU owner should take apart their rifle remove the excessive grease inside the compression chamber and on the spring. Dieseling is not good for any rifle. I did clean mine after smelling lighter fluid after each shot.

    …i'm craving a .22 walther lgu varmint now….  i read guys like these walther underlever better than their hw's or aa's…. the lgv i have with the wood stock is a heavy gun for a non-magnum…..  i know the platic stocks for lgu / lgv rifles are cheezy , but it may be better than an 11 lb air rifle…..  i just want someone who has one and a chronograph to confirm the 800 fps rating.   the regular lgu was more like 650-700.   one guy selling his lgu varmint said that his crono'ed in the 660's – just like the regular .22 lgu rifles.  i've never had an underlever that i kept. i had a chance to get one of the older hw77k underlevers in .177 for $350 , but i couldnt stretch it – i didnt know the older ones had a larger tube then and were sought after.   but i'm not paying $200 for a browning leverage, or gamo cfx, or a hatsan……maybe end up with a .177 diana 430L combo on sale at a of a for $270.   – paul.
