I'm glad it's finally here, the LCR line has needed a more powerful choice with adj. sights and .357 or .327 will fit that need. I'm not interested in a 9mm revolver with a 3 inch barrel, to me .357 is just better in a 3 inch, but to each his own.
There's not much left to add to the LCR line with the 3 inch steel models now being made. Different chamberings will come in time, I'm not sure I want a .327 like I use to.
I'd still like to see (and this is not my idea, it's something I read on another forum) a "Modern Service Revolver" which is a larger frame LCR, more along the size of the GP100. Still has the polymer fire control housing and grip, but the cylinders are larger to fit 6 or 7 rounds of .357 and has a 4 inch barrel, if not longer.
The frame being larger/thicker, maybe that then allows the use of Aluminum for the frame. Maybe use a steel or tungsten insert for the top strap to prevent flame cutting.
Just an idea I'm throwing out.
