Greetings, I just purchased my second SIG, and I went with a 229 carry. From what I understand these are a bit of a unicorn. It is a 229 with a shorter barrel and slide. There are a couple resources that suggest it is the 224 slide with a 229 frame. I was wondering if anyone has one of these I would love to hear about holsters, magazines, and the like. Lastly can anyone confirm the general E-2 magazine thing. From what I gather you can put E-2 grips on any sig, can not put standard grips on an E-2, can use standard mags in a E-2 but not E-2 mags in a standard gun?
