I think if they search, the new members would fine all the answers on the forum -- a fair amount of us, including me, use a Hedley pocket holster. It's so small, that IWB is quite comfortable, but pocket carry has certain advantages (mainly, allowing you to be in a "ready" position, w.o. having to let anyone else know.)
Most of us use speer gold dots in 115 grain. I wouldn't carry WWB ammo -- if you want to carry hardball, try to find the highest quality ammo you can -- something built to ALWAYS work.
Clean and oil every time, change the springs every 100, I guess -- I never had a problem w. the old standards, but I do change the springs at 100 now.
Oh, and it's ALWAYS in my pocket, unless A) it's banned by law B) I'm at the plant/ranch/some other nasty place where I can open carry, and I've switched to either my SP101, or if it's really dirty, something plastic. (either a glock or XD)
