I shot my new Shield 45 on Monday. I put about 150rnds through it with zero malfunctions. It's an accurate pistol for being so small. I was also pleasantly surprised at the lack of recoil in the gun. It's really not bad at all. I really enjoyed shooting it. The ammo cost is the only negative I can think of. I too have a decent supply of 9mm. However, I'll be stocking up on more 45. I really like my new Shield 45. I think you would too.
