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:
".. It looks really good, feels good, color turned really good and the manual is probably the best I have seen in any product.. 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. 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
