Well, actually the appeal for me was that at the prior price, with the 20% off coupon offered by Sig at the prior price, I could afford to buy a carry sized P320 in .45 caliber and buy a 9mm compact caliber X-change kit.
I need a compact but reasonable sized 9mm polymer framed, striker-fired pistol and I don't particularly like subcompacts. But in actuality I seldom carry, I really prefer shooting .45 caliber out of either a full-sized pistol or at least one with a full-sized grip, and I would have left the pistol in that configuration as a home defense gun or truck gun 95% of the time.
It would have been very nice, however, to have the option to switch to the 9mm caliber for practice with more economical ammo and have exactly the same trigger action. This type of thought was much encouraged by Sig.
So why not just buy two complete pistols? Simple, I can't afford it at this time. So it looks as if I will just be buying the 9 mm carry piece. In that case, the HK VP9 and PPQ definitely deserve consideration. I accept that the 9mm compact P320 is also a very good pistol but after having researched the P320 for over 6 months and led on with the thought of having the same pistol in both 9mm and .45 caliber with two different grip sizes, I do not look very favorably on Sig Sauer for this overnight price increase before either the 9mm caliber X-change kit or the .45 caliber pistol have even become a reality. Sig Sauer hyped up the modularity and then pulled the rug out, insofar as I am concerned. I simply don't trust the companies that practice bait and switch tactics and want I nothing further to do with them.
You might not agree with that but that is how I feel.
