Shawn and I went to the range. Side by side there is a noticeable difference in the triggers. I don't think its much though. I think it helps never really shooting it before it left as well.
I put 100 rounds through mine with zero issues. I even used the extended mag that was giving me fits before with no problem.
I think I shot reasonably well given my lack of range time.
I'm happy top have my gun back. I love it. I'm still not pleased with how long it was or how it was handled. But it is what it is.
