A little hotter than the Fiocchi, cleaner and more consistent. I love a little Baby Browning, Colt Vest Pocket, Astra Cub, Colt Jr. Galesi, Beretta Jetfire, or Bobcat. RELIABILITY, MAY BE AN ISSUE, SO CHECK THESE IN YOUR GUNS, and IF YOU KNOW HOW, adjust the feed lips on the magazines accordingly, or go back to FMJs! Contrary to Jeff Cooper's philosophy, a face full of .25ACP will take the fight out of most people, not just make them mad. The powder burns and muzzle flash alone will allow you to close in and start taking out eyeballs and adding nostrils. Just remember "6 or 7 rounds and you are out" with the truly tiny guns! I am probably the ONLY person on the planet who carries (a) spare magazine(s) with his mouse guns. I think I have 4 extra magazines for a .32ACP. You might have some legal problems, but that guy that broke that pool cue across your skull stopped beating you with the fat half of it. When the jury sees your tiny Astra Cub, the prosecutor will have a hard time convincing anyone you had any intention of killing someone with a gun that fits inside a pack of cigarettes. Don't laugh! Up until many of these little European guns were taken off the streets by the Gun Control Act of 1968, many people wound up on a marble slab from the tiny .25ACP! In that same context, back when these were still popular and the .38 Special ruled the roost in every cop shop, I saw a .38 Special bounce of one of a pair of nare-dowells, forehead's. Both his eyes were swollen shut the next day, but the witnesses to the scene were not the only people who thought he was going to die. Chris mellowed out a lot after that incident. He could have just as easily taken a .25 through an eye and died. There have been some teeny tiny .45ACPs, & 9mm that were so small, they are effectively manual fed derringer type guns, but they are about as fun to shoot as slamming your hand in a car door!! .25 ACP is more reliable in an autoloader, and it can be really fun, but expensive, to shoot! I enjoy trying to hit targets with tiny pistols! It is not easy, so be forewarned! This is some of the best .25ACP defensive ammo money can buy. Gold Dot is okay too, and the Fiocchi is also more than adequate. 25 being what it is every advantage you can get is welcome!
