Weill I have tried and I give up. Over 400 rounds in the past two days and I can not get the hang of it. What parts are needed to convert a factory LEM gun to v1? I am just exploring the option. I am going to shoot it some more today and probably place another order with SGammo soon lol. I don't want to give up but It's a real struggle especially when I can shoot my other pistols well. Still shooting low no matter what hold I use with the cover sight picture.
