I bought a P64 some time back and it has been a great little gun, especially since I paid well under $200 for it. As I discussed previously, it isn't perfect. The biggest problem is that it's a commie relic, and so suffers from common communist complications (i.e. bad trigger, poor quality metal, lack of fit and finish). My solution is most likely going to be the Ruger LCP, and here's why.
Though the LC9 is probably closer to the P64's footprint while being more powerful, the LCP is just stupidly easy to hide. The P64 is sort of my "deep concealment" piece, and the LCP would be better at that. Ammunition variety is slightly better for .380ACP, though that really isn't part of my consideration. Both the 9mm Makarov and .380ACP are pretty slow movers, and I doubt their effectiveness with HP or frangible ammo. I would rather poke a small hole deeper than make a bunch of ugly but ultimately non-lethal flesh wounds. I'm not saying it's bad to carry hollowpoints in a small caliber, in fact ammo companies have probably tuned their .380 ammo to perform at .380 velocity. Makes sense. I'm just saying that in my head, a low-energy round has a better chance of piercing blood-bearing organs if it is an FMJ. I may come around to carrying .380 hollowpoints, but right now, I'm not inclined to do that. See some great ballistics gel tests below:
The guy in the film is correct that bone would have been a factor that could have prevented the "over-penetration". I would bet that hitting a bone on the way in would have slowed those little guys right down. Having shot cow skulls out on the farm, I can say that bone does pretty well at stopping handgun rounds.
The Gold Dot here only made it 10" into the gel block. I'm not sure that would be real impressive if it would have caught a rib on the way in...
And even worse, Win Ranger-T only made 8", though with impressive expansion. Again, what good is expansion if it doesn't penetrate?
There are a number of other .380ACP ammo tests that also show either erratic or poor penetration with HP ammo. Remington's 102gr Golden Sabre failed to expand, and others that did open up made it less than the FBI standard of 12" in a calibrated block. You can carry what you want, but if I can get an LCP to feed FMJ flatpoints, I'll carry those.
