I have the shield, glock 42, and glock 43 and have shot them a bunch over 500 rounds each. I first got the shield and liked it so much I let my wife shoot it, big mistake. She sold her glock 19 and now carries the shield. We have had no problems at all with it and it shoots great. Than I bought the 42, one of the first, worst mistake I ever made. I had every problem you could imagine with it so it went back to glock. came back and flawless. it also shoots excellent and fast to target. Now comes the 43, I have around 500 rounds through it without a hitch. shoots everything you feed it and comes back for more. I carry both the 42 and 43 just depends on how I want to carry. the 42 is excellent pocket gun 43 is a little bigger but still works in the pocket. I was going to pick up another shield instead of the 43 just due to price. I got blue label pricing on my glock 43 but the price was still almost $75 more than the shield. I love my glocks but for the money the shield cant be beat. It is bigger and heavier than the 43 and I have a limitation when carrying so I needed a smaller gun for comfort. you cant go wrong with either
