Of all the various guns I've shot (even a number of full-size 9mms), the Shield is just nearly unbelievably comfortable to shoot. Every time I shoot it, it amazes me at how flat it stays and how negligible the recoil is. Sure, you can certainly feel it, but there's very little muzzle flip -- it seems to push back in your hand as much as anything else. I was out shooting my CZ 75 yesterday, a gun known for being easy to shoot, and the Shield is at least as comfortable to me to use.
I'm impressed with the Shield every time I go to the range. I have probably 500 rounds through it now, including Winchester 115 gr, Federal Champion 115 gr, Perfecta 115 gr, Hornady XTP 124 gr JHP, and Federal Hydra-Shok 147 gr JHP......and not a single malfunction of any sort.
It's just a real sweetie.
