Only 1 of my guns has a safety switch. Learn to keep your finger outside of the trigger guard (I have it pointed forward, right below the slide) until U get ready to shoot.
I know some people like a safety - extra security. And, the Glock fanatics spin into a tizzy anytime someone says something about it. Over time, U will get used to it. The gun won't fire if you drop it. But, if U feel better with a manual safety switch, but one w/ it. Look at the FN - 9/Browning Pro 9. I like it better than the XD. It has a manual safety and the FN can be gotten with a stainless slide at a good price.
