View Full Version : Don't sell the 9mm short too quickly

Today's ammo is not the same as the stuff you may have seen 30 years ago.

Here is a wound channel video of 9mm Hornady custom (https://www.youtube.com/watch?v=BTGmlVQpLrs), if you want to see what these things do.

Rather than write an article on the subject myself (as I have done in the pas (http://crypto-corinthian.blogspot.com/2012/03/gun-advice-for-newbe-1.html)t), I took the lazy way out
and found a reasoned and balanced article someone else had already done.

http://www.safetysolutionsacademy.com/0282-make-switch-from-45-acp-to-9mm

Lets look at some of the important points of wounding capacity that we must understand when
we compare 45 vs 9mm. Wounding capacity is really the ultimate reason to switch from 45 ACP to 9mm.

Most people look at the terminal ballistics of ONE 9mm round and compare it to ONE whatever round and
use this as definitive evidence as to why one round is superior to another. If I only had one shot? But I don’t
only have one shot. I carry a standard capacity automatic. The terminal ballistics of EVERY round that is
combat accurate matters not just the performance of a single round in gelatin. My rate of fire with a 9mm
is significantly faster than with a 45. 5 holes with a 9mm quite possibly trumps 3 holes with a .45 in the
same time span in just about every situation. Of course these numbers are a matter of speculation but
I think we can agree that rate of fire is increased not just for me, but for nearly everyone when we switch
from a .45 to a 9mm.

Some folks out there have criticized instructors for making the change to 9mm so that the instructor can
impress the student with faster demos in class. I suppose some folks may make the change for that reason.
The “impress the students” part is the problem there, the shoot faster is the right reason in the first place.

In most situations the wounds generated by .38 – .45 are not discernible by ME’s by entry wound,
exit wound or wound cavity.

If the wounding capacity of individual rounds is about equal between calibers then more rounds in the threat
give us much more wounding capacity.

In addition he discusses the cost of ammo, and its impact on practice. That is one of the reasons I recommend
it for any serious self defense shooter, since I also recommend putting at least 100 round a quarter down range.

I agree, practice, practice & practice.
