Well my .40 sheild has a I find to be a overall nice little package. It does have some minor issues, the most annoying is how far left it shoots and the gross sight adjusments required to bring impact to point of aim. This problem seems limited to a small # of pisyols and I cannot fault a complete series for an occasional manufacturers defect. That being said a couple of issues raised by the OP are somewhat valid:
1. The mags are hard loading
2. With the short magazine the pistol is a bit nose heavy, well balanced with the long mag.
I have not experienced any other issues, the trigger is as expected for the type of action and the yellow takedown lever thing is a novel non-issue. o mag wobble, mag drops or malfunctions, the only real annoyance to me is the rubber grip extension on the extended magazine. That damn thing sliding up and down when I load the mags with rounds is annoying and with my fat hands I have pinched my fingers on mag insertion...I wish it were firmly attached in place rather then sliding about.
Overall I like it very much and it groups nice and tight.
Get an UpLula for loading and add a titch of glue to the lower side of the rubber grip. Leave a round out if hard loading until you get it broke in. I DO NOT under stand the nose heavy thing Danged gun ain't big enough to be "Nose heavy"
