Which ones have you bought for the 43. My 43 is due in any day. I am going to try an IWB
Alien Gear IWB - very comfortable if I'm carrying all day
DeSantis Pocket Holster - great for grab and go. fits well in cargo shorts or back pocket of jeans
DeSantis Soft Tuck IWB - great grab and go for jeans. I added a UTILCLIP to it
MIC - haven't used it yet
Fobus GL-43 Paddle - Most comfortable of them all and great to just clip on and go. Not great concealment but i'll use it the most during the winter.
