Just to clarify, since Sig offers so many variations of the P220... If you are referring to the 220 Compact Carry, I've had mine for about a month.
I have emailed back and forth with Crimson Trace, and confirmed that they do not - yet - have a set of laser grips for this model. They did encourage
me to fill in the form on the website for desired furture models. (I'll post a link later if I still have the email, but you should see it on their main page.)
I was given the distinct impression that these are on their 'to-do' list, but that more requests from customers could nudge the priorities a bit. I
haven't looked closely at Hogues or anything else, as I know that ultimately the CT grips are what I want, but I'd email Sig or Hogue if that's the route
you want to go. Hope this helps.
