Triggers on DAO type pistols have long trigger pull throughs. Nature of the beast. Taking up the slack in these type triggers takes getting used to. Much different than firing traditional DA/SA pistols or revolvers altogether.
This might explain things a bit better.
There is a good case for the .380 ACP as a defense cartridge.
Better than the .32 ACP and smaller cartridges, the .380 ACP has the balance of light recoil and is effective with the right loads as a defense cartridge going for it.
There are those who do not want to carry a revolver and want the cartridge capacity of the pistol. Yet want light recoil and decent protection. Short recovery time between shots over the more powerful cartridges is also a bonus.
There's the story about the jeweler who has 11 Rossi revolvers around his business for protection and used them for that. Now put that same equivalent in a pistol format and that's what you have with the .380 Taurus pistols. Just in one package.
Taurus, Bersas, CZ 83s,Beretta 84,85,86 series, Walther, and the others all have this.
As much that is made over deep penetration and caliber size , these are not the only requirements for defense. The .380 ACP has done that on many occasions as well with the other ballisitic factors included.
Real world records show the .380 ACP does it's job well.
One can use anecdotal evidence or other means to show failure to stop. This can be done for even the larger bores.Police and tacatical journals, as well as other periodicals document these stories with great regularity.
Newer generations of JHPs in all the calibers have been designed to penetrate deeper,stay in one piece, retain bllet weight, and expand or deform at very low velocities. 670 fps and a little higher. That slow enough for you folks?
Actually the .32 ACP bullets has benefited from the same technology as the other calibers, but I digress.
There are those who have trouble shooting the more powerful cartridges do to physical reasons or those who do not like the muzzle blast or more recoil of the larger or more powerful rounds.
Don't have to be old to be in this category. Can be any age. Can affect anyone at any age.
For some,the .22lrf is all they can handle or have the ability to handle. Looking down on these folks is ethically and morally wrong.
So what ever cartridge one is limited to or can handle, my hat is off to them.
Bigger and more powerfull is nice. No argument there.
Then there is a niche where that is not possible,desireable, needed, or wanted. One has to go with what they know and can handle.
Happy trails folks.We're all in this together. 8)
