I would have to respectfully disagree with the assessment that the 110s would not be a good defense round for the 3"...

The loss of 1" of barrel length will reduce velocity 50-100 fps and would make bullet blowup far less probable...that and how much penetration does one need on an average human...

If I'm carrying a .357 Magnum the LAST thing I would ever stick in it would be a .38 Special of any variety...I'll take a little more muzzle blast that I'm not going to even notice anyway when defending what's most important...my life....
