I have a 40 shield. As far as range ammo, I've only used PMC Bronze 165 gr. 40D. You can get it by the case for about 15.00 per box online. It cycles very well in my gun and seems accurate. As for SD. I have used Hornady Critical defense, and Winchester Ranger T-series 165 gr. both cycle well, and are very accurate. The T-series is my choice to this point but is difficult to find. Good luck
