Looking at the prices on shields lately and compared to the pretty consistent pricing on the glocks I wonder which one of these guns might fit under the "most durable" category? You cannot ever get something for nothing. I am in the market for a .40 to shoot 200 grain Hard Cast or 200 grain XTP bullets from as a hiking/backpacking gun. I have a 9mm shield and shooting it against a rental gen 4 27 in .40SW I found I could shoot both about the same at 15 feet, the G27 was snappier but the 9 shield seems snappier to me than a G43 shooting the same loads. I have to wonder if the lower priced shield will hold up to consistent shooting of reloaded hard cast 200 grain bullets or the 200 grain XTP. I am only interested in the gun for the heavier bullets driven at close to 900 fps and I don't know if anyone has fired a 40 shield a lot with heavier bullets driven at their maximum velocity from its short barrel?
