I've been holding off buying another X300U in anticipation of these.
I'm returning mine, sadly! It will not fit in a Glock 17 6390 without sending it to an outside company to have it modified. The wait time is about 12 weeks and I can't part with my duty holster for that long. To modlite's credit, they were going to pay for all of this but it just didn't work out for me so back it goes.
