Lone wolf is the best in the game. 5

Posted by Harry on 24th Oct 2023

I built me a g23 and G27L. I had extremely difficulty finding reasonable priced parts for this .40 cal model I was having a lot of feeding issues firing pin tips snap etc. Once I put all the lone wolf upper in I went to have zero issues. If you looking for well design quality parts lone wolf is the way to go.
