Not quite right. Glock didn't sue over the SW9VE or the SV40VE. Glock sued over the earlier Sigmas that are no longer in production. The 'VEs' came after the lawsuit, and the changes that make them 'VEs' were specifically to make them less similar to a Glock. I have a very early 9VE that I bought right when they were first released. It has been stone reliable and has fired thousands of rounds. The Sigma trigger doesn't behave or feel like the Glock Safe action trigger. The Sigma trigger is designed to feel like that of a DA revolver, and it does. You can definately shoot a DA accurately, but is a different skill than shooting a SA or a striker fired pistol.
