It would be nice to compare two similar frames and loads with a compensator!
Here's a nice chart that has the me ft lbs. http://www.chuckhawks.com/handgun_po....htm....notice
the .45 acp in Me (ft lb) column compared to the 40 S&W.
But this chart....dunno how accurate it is though surprises me! http://www.freerepublic.com/focus/news/849728/posts
According to the chart, the 40 is neck and neck with the .45 in stopping power!
Now they compared the fmj in the 40 as a flat nose and the .45 was just fmj suggesting round nose. and the 40 had it beat in penetration but the true comparison was the hallow point! neck and neck? Your thoughts welcome there.
