I could never afford practice ammo. Yet another factor in leaning towards a 9mm.

I think a 9mm will do fine, but as guys we like to think that the bigger cal of a .40 really changes things that much. Maybe I'm crazy. Thanks for all the replies!

I have another post dealing with XD SC vs Kimber UC II. In that disussion there was a bit of disagreement btw 9mm vs .40.

Here are some ideas that I have - and I would love for someone correct me becuase this is more of my gut feeling than anything that I know or have experienced:


9mm has increased risk of shoot through during a possible self defense encounter due to higher muzzle velocity and smaller round (less friction due to less surface area - it keeps velocity).


Is there any truth to that? Right now I carry .45 Speer Gold Dots and don't worry too much about shoot through.


If I go the XD route (still undecided) then I would like to have some insight before I tackle the 9mm/.40 decision.

I'm up for all the "HO's" y'all will give me.

Thanks again,
