I don't like safeties on any carry gun especially a pocket one. Besides to my understanding the Solo has a 6 1/2 - 7 pound trigger it is not like a 1911 trigger so why the safety?
I saw the solo last week, it looks just like a little baby Kimber 1911 without the hammer. The shop only had one and it was not for sale. I was told they had about 30 on order. It would definately disappear in a pocket without any problem. It almost looked like a toy.
I handled one, and it has a very nice fit & finish. I personally don't like the safety but the heavy trigger is fine (IMHO) for a pocket gun. They do seem to be in short supply, so someone is really liking them...
