I hear what you're saying. I don't necessarily have my heart set on pocket carry.
I put the 26, the 43, and the shield side by side today to compare sizes. Length of the slides were pretty much identical. The 26 was obviously quite a bit thicker than the other two. I was a bit surprised to see the length from the top of the slide to the bottom of the grip. The 26 and 43 were pretty close to the same but the shield was a fair bit longer than either of the Glocks. If you can pocket the shield, I should be able to pocket the 43 as well. Not so much the 26 because of the width I imagine.
