I own a Springfield Loaded and an SR40C. Dare I say it? I'm better at the range with my 40 than my 1911. Not that I'm against the 9, I would like to have a p226 someday.
I shoot a lot and for that reason I also reload. My current monthly budget dictates that I must choose and reload for only a caliber or two at the most. I really hated to part with my G22 and G27 but the G17 lets me get more bang for my buck and the G30 I have found to be the most accurate (at least for me) of the Glocks I owned so it has replaced the G27 as my edc. Having said all that if my financial situation ever improves I will again have my .40's. I really,really hated selling the Gen.4 G22, I really loved that one.
My SR40C fits my hand like it was custom made. Feel, fit and comfort is a consideration. The quality for the cost makes this choice a bargain. Stocked up on ammo a while back when I saw the writing on the wall. Ammo may very well become the new currency.
If I want more of any bullet I just cast more. Self sufficiency has a way of isolating all of these supply and demand problems from my little world. You should give it a try, excellent hobby, .40 bullets cost 2 cents each...shoot .40 for under 8 cents a shot.
All of my buddies and I except for 1 have .40's, The only other one has a 9. We can find .40 ammo no problem, I haven't seen any signs of anyone bailing on it.
I haven't fired my .40 in a long time, but during the last 'panic' ammo was available in .40 while 9mm was cleaned out. That was enough to convince me to hang onto it.
I am a huge fan of the .40s&w . Good power to size ratio . I look at it this way, I like the M&P platform and own a 9 , 40 , 45 and using standard bullet weights the the payload delivered from the 40 is 2880 grains vs 2530 for the 45 and 2646 for the 9mm. (180gr 40, 147 gr 9mm 230gr 45) so I can definitely see the up side to the .40s&w .
I've carried a G27 for years now. I first decided on .40 S&W when it was becoming the LEA caliber of choice in my area because I figured it would be plentiful and easier to "pick up" in an emergency. I briefly owned a G26 and found it more uncomfortable to shoot than my G27. I'd like to get either a G22 or a Charter Arms PitBull in .40 to back up the G27, one of these days.
