Last week took the new Shield to the range and shot about 300 rounds. One failure to extract on a handload. Took it back to the range today and shot about 250 rounds. Zero failures. I am reasonably happy.
In fact, if I can come up with a magazine carrier that works with these mags I may very well shoot this in my regular IDPA match in the CCP division instead of my mini-1911 .38 super. We shall see.
