Test Gun: Sig P229, Kahr MK9. Barrel length: 3.9, 3 inches. Ammunition: Federal 9mm 147gr HST. Test media: 10% Clear Ballistics Gel. Distance: 10 feet. Chronograph: PACT 1 XP with inferred sky screens. Five shot velocity average: 967, 916fps Gel Temperature 71 degrees. This is the fourth installment and probably last with the 9mm HST line. Here is a link to the other 9mm HST rounds I tested. http://www.general-cartridge.com/blog/federal-9mm-124grp-hst-in-clear-ballistics-gel http://www.general-cartridge.com/blog/federal-9mm-124gr-hst1-in-clear-ballistics-gel http://www.general-cartridge.com/blog/federal-9mm-hst-147gr-p-in-clear-ballistics-gel I got an average velocity of 967fps out of the P229 with a high of 975fps and a low of 953fps.  I switch back to my Kahr for the short barrel testing and got an average velocity of 916fps with a high of 929fps and a low of 893fps. 
In the bare gel, out the P229 the first round had a velocity of 966fps and penetrated to 15.25 inches and had a recovered diameter of .67 inches. Round two hit at a velocity of 976fps expanded to .65 inches and also penetrated to 15.25 inches. 
In heaving clothing covered gel, the first round had a velocity of 976fps, penetrated to 19 inches and expanded to .65 inches. The second round had a velocity of 962fps expanded to .62 inches and penetrated to 16.25 inches. 
Out of the Kahr in the bare gel, the first round hit at a velocity of 922fps, penetrated to 16.25 inches and expanded to .65 inches. round two traveled at a velocity of 914fps, also penetrated to 16.25 inches and expanded to .63 inches.

124 and 147 grain HST's are the best!
The bullets expand the same or even slightly larger AND penetrate deeper after passing through clothing that most other hollow point designs choke on. If you aren't at least considering carrying these, you are dumb.
