I traded a Mossberg 500 20 gauge for this weapon (new). I really bought it for the range but, in the trade in, I gave them two boxes of sluggers and two of bird shot and they gave me two 20-round 40 grain target ammo. I've got range ammo for this gun and am no newbie (have had a permit since 1992). I would like a simple 50 count box of defense ammo for this weapon, not that I don't trust the people I'm dealing with, but they failed to provide it to me when they really should have. Any input on what to buy, where to buy (if my local supplier is unable to provide and online seems impossible) and how much (since I have to pass quite a few through the gun) would be appreciated. Nice little gun, looks badder than it is. I have a S&W 637 but am not happy with the range performance (lots of recoil even with low grain ammo). Any ideas? Help appreciated.
