Heres my dumb post for the day. I was at a meeting of church security team, for a presentation. At some point the age old caliber war started. I know to not engage, i just listen. Now i heard 380 is same as 9mm fall out of a mouth and bit lip really hard. Its not my intent to beat dead horses or debate physics. But this morning i found this cool piece of 2 inch thick polycarbonate of some sort. And decided lets play a minute. First up my ever present lil companion .380. Bang meh , then 9mm much bigger impact but meh, then .40 sw little more still meh. Soo 5.56 now were getting somewhere full penetration but i believe i have a better solution for the 7 yard/21foot test. Lets see about a good ole 20g slug, yup thatll do it. What have we learned ? Nothing really but if attacked by a big thick piece of lexan and ya what an instant complete destruction dead stop, use a slug i suppose Nuff said. Ps NO my dang lil 380 is not the freakin same as 9mm at all not even a little bit Aaasrrrrggggghhhhhhh!!!!!
