Look under the SP-01. There are basically three variants. First, there's the model with the decocker. Basically, if the hammer's cocked, you press down on the decocker to safely lower the hammer. There is no manual safety to prevent you from pulling the trigger--the decocker simply transitions the gun from single action mode to double action mode. The second model has the manual safety and no decocker. With the hammer cocked, you can activate the safety, and the gun will not fire. This is what is commonly known as "cocked and locked." The third model is the Shadow, which basically is the same as the second, but with some upgrades (hammer, sights, grips).
I may be wrong, but you seem kinda new to the world of firearms. You're in the right place--this forum is filled with great info, and you should get to reading as much as you can post haste. A basic firearm safety course of some sort may also be in order. Hold off on purchasing your first handgun til you've done both. That's prolly the best bit of advice I could give you.
As to your original question: I own (or owned) a Glock 17, a Glock 19, a Glock 34, a CZ SP-01, a CZ P-01, a CZ 75b Tactical, and a Kadet kit. They're all fine weapons, reliable as heck, and more accurate than 90% of their owners can hold. That said, the SP-01 and Glock 19 are different animals and really cannot be compared (it's like comparing an Accord to a Civic). If it's going to be your only gun, and it's mainly a range gun that will double as a home defense gun, then I'd suggest getting the CZ with the Kadet .22 conversion kit. GREAT training combo. Gets the nod in terms of accuracy (although Glocks are no slouch in that department, either), while the Glock gets the nod in terms of durability and reliability. IOW, I think the CZ SP-01 makes a better range gun, while the Glock 19 makes a better working gun.
Just my opinion.
