The Apex Tactical Sigma spring kit came out today. I can't wait to see what kind of improvement it makes on my SW40VE!

I've really been looking at 9mm's and I've settled on the M9 or PX4. Just something about the Beretta I like. I would love opinions from any of you that have first hand knowledge of both.
