Hi Andrea, any 9mm cartridge will work. 9mm is also known as 9mm Luger, 9x19, or 9mm Parabellum. You want FMJ (full metal jacket) for target/range practice budsgunshop.com/product_info.php/products_id/63308/cci+blazer+brass+9mm+ammo+115gr+full+metal+jacket+50+round+box ,
You want HP (hollow point) for self/home defense budsgunshop.com/product_info.php/products_id/55840/fiocchi+defense+dynamics+9mm+luger+147+gr+jacketed+hollow+point+jhp+50+bx+20+cs ,
Stay safe & have a great day!

If you want a low cost practice round then this is what I run in my Glock 19 gen3, CCi Blazer Brass.

Hi Andrea and welcome. We answered this once but, here is the info you requested. Most any standard 9mm ammunition/bullet will work. For target and self-defense, I highly recommend blazer brass (Target) in 124gr: budsgunshop.com/product_info.php/products_id/63381/cci+blazer+brass+9mm+124gr+full+metal+jacket+round+nose+50rd+box ------------------------------------------ and Federal Punch (high expansion) jacketed hollow point (for Self- Defense): budsgunshop.com/product_info.php/products_id/121123/federal+pd9p1+premium+punch+9mm+124+gr+jacketed+hollow+point+jhp+20+bx+10+cs ---------- Cheers, stay safe and enjoy!
