Wanna guess how I came to give such good advice? It really is the archer not the arrow. You can chase that latest technological theoretical advantage, but it really comes down to practice. I sold my Tanfoglio Limited and now shoot better with a SW model 610 that I ever did a bottom feeder. Maybe not always faster, but better both mentally and physically. You don't see the same people on the top each year because they milled off a few ounces or got the latest gizmo. They are there because they get paid to shoot and do so every day.
