As much as I like .25's I think the round is destined to be a hobby round, no one is going to buy a gun like a Taurus PT25 or Beretta .25 when a Kel-Tec , Bodyguard .380 or LCP is smaller and lighter, more reliable and has a more powerful round.

There will always be mouse gun buffs who will keep the old .25 alive but I think the number of people carrying one for defense anymore is very low. I remember even back in the early 90's the "Baby Nine" as the gun rags and range buffs used to call it, was still very popular and Taurus and Beretta sold tons of their little .25's.

If I need truly small I can just use my NAA .22 LR Mini revolver.
