I voted for the SIG-Sauer P229/P320.
Truth told, I have experience with only a few of the .40 cal pistols on your list, so take that into account.
I own a SIG P229. That pistol was designed for that round specifically and it handles the recoil of the cartridge extremely well.
I have a P320 full-size and a P320 compact, but the full-size is chambered in .45 ACP and the compact in 9 mm Luger. I did shoot a full-size P320 chambered in .40 S&W and I found that it too handled the recoil very well and was amazingly accurate. Based on my experience with my P320 compact, I strongly suspect it would do fine chambered in .40 as well.
I have shot an FN FNS .40. I only shot one magazine through it at a range where I traded guns with the guy next to me. I thought it shot quite well, but it was not as comfortable in my hand as the P320 and the trigger was not as good. I would agree that $360 for that pistol is a hell of a good deal if you are on a budget, however.
I am sure I have shot a Glock chambered in .40 sometime, somewhere, but I don't much care for Glocks so it was not a memorable occasion.
If you are looking for a striker-fired polymer-framed pistol, I would go with the P320. For a TDA all-metal pistol, the P229 is hard to beat unless you want a mechanical safety.
Forty caliber S&W is not my first choice of chambering in a sub-compact pistol like a Shield due to its recoil characteristics and the limited magazine capacity.
