Only our tactical teams have had them approved up until last year. Now all of us can qualify with/carry an X300, which is ginormous on a CCW'd P229. XC1 is in testing....which I would like.
Even when the XC1 is approved, I don't want to use it unless I get myself some substantial training on it. Whether that's from personal out-of-pocket training or agency training, I think it's necessary. I'd rather not have to use my personal liability insurance because I negligently smoked some dude on accident. After doing some reading on the topic, I feel that carrying a WML without specific training for it is the same as carrying a gun without specific training for it. Just because you have a dick doesn't mean you know what you're doing, that whole deal.
