Just like the title says, a Smith & Wesson M&P Shield 9mm firearm, with the flush 7-round magazine, will fit in the front utility pocket of a Condor H20 pouch. I did the test fit with a 40oz Kleen Kanteen in the main compartment also.
I'd assume that the .40 cal Shield would fit too; I believe it is the same size as the 9mm. I know that the .45 cal Shield is a little bigger than the other two versions. The interior dimensions of the pocket are 6.5" x 4" x 1", so the zipper takes just a little persuasion to get around the rear sight and the outside bottom edge of the grip.
