I just shot my new model 27 and it's more accurate, or at least easier to shoot than my old model 23. The first box of Win White box was kind of all over the target but the second box was my handloads with 5.3 grains of Bullseye w/155 gr. JFPs and they just kind of go where you point it! I couldn't be happier with this gun. I've been using my Kahr PM40 for carry but this new Glock is easier to shoot accurately than the Kahr, by far. I tried to attach a pic but I get a message that it exceeds the file size limit even though it's only 1.43mb.
I found the 27 to be one of the most accurate guns I've shot as well. It recoiled a bit too much for me, so I don't have it anymore, but it was one of two guns I've owned which I could say it was pinpoint accurate.
