Hi Brenda, yes this is good for a southpaw. It has ambidextrous safety, ambidextrous magazine release and the trigger on the P17 is actually quite light (around 3 lbs), and it takes little effort to rack the slide.
Stay safe & have a great day!

This model has an excellent trigger & The threaded barrel, Picatinny-style accessory rail, ambidextrous safety, ambidextrous magazine release and three (3) 16rd magazines come standard. That’s a ton of value added in such a small package, even for a Lefty!!

Hi Brenda and welcome. Yes to both Ma'am. Cheers, stay safe and enjoy!
