Please don't!25acp is overpriced as ammo, but much more reliable as Centerfire than 22lr is as Rimfire... MUCH!
I don't deny the 22lr is a viable self defense caliber because if placed right any caliber can and will kill, but a 25 does a lot more damage to a computer hard drive and centerfire is superior reliability.
I'm looking at picking up a FIE Titan in 25acp. There's the Astra 25, Beretta 25, etc. If she likes DAO triggers the Beretta would be the way to go.
There are two titans, originally made of steel and now of cheapo Zamak. I'm going to give this thing a shot, as the Beretta is overpriced for such a small low cal junker. Besides is not for protection, I've got that more than covered already, this will just be a plinker.Please don't!
Get a Beretta 950. It will go bang every time you pull the trigger. EVERY SINGLE TIME!!!
