I may be the first to publicly spill the beans here
Tonight I decided to run out to the gun shop for a visit and a cigar, and was handed a little flyer of interest. Then waited for the UPS delivery truck until after 9:00 p.m., but he was a "no show". It seems that Sig is now offering the P250 in a "combo kit", only in the 9mm configuration with both the large grip frame and the sub-compact grip frame in a dual combo case. Two uppers, two grip frames, and one fire control mechanisms. Not sure of the counter price yet, but it should be a substantial savings over the "bought seperately" prices. The P250 is very easy to take down, all the way to the fire control mechanism, as I was able to dismantle the medium framed model in the display case in about a minute without the use of even a drift pin or punch, and had never seen or done it before.
I'm not personally in the market at the moment (wish I was), but I can see the appeal for this one having a full sized Sig (1.4 inch width), and a sub compact Sig (1.1 inch width) in the same box, with a slight bit of "tinker toy" work. I'm going to take a wild guess that the "out the door price" will be around $900, or less, but that's just a complete SWAG on my part.
I can't wait to put the stopwatch on the conversion process.
oh... it's called the P250 2Sum
