I'd love to try it out, but hope that LWD heeds the sentiment of several posters here who would prefer a frame without the damned finger grooves. With the advent of the factory "SF" models, the opportunity for LWD to innovate would have to entail combining the accessory rail with a Gen-1 style grip frame. Interchangeable backstraps would be good, too, since that is an oft-requested feature.
Variety is not a bad thing here.
