Since this forum is populated with some of the most knowledgeable pocket gun people around, many of whom were into pocket guns when .22 and .25 were the only options (which really wasn't long ago - the Seecamp was the only game in town above .25 until the late 1990's), I thought it a good place to ask this question.
My wife is starting to get serious about carrying a gun at least some of the time. She recently asked me to get her a gun purse for her 4" Springfield XD. I ordered one that she picked out from Coronado Leather, but would also like her to have smaller guns that she could potentially carry on her person. As I see it, she will need 2 more guns: one that is as small and light as possible while staying within the usual minimum caliber guidelines (hopefully a subcompact 9mm), and a true pocket pistol.
She does not have particularly high recoil tolerance, and did not like my Kel-Tec P-32 the 2 times she tried it. This is the lowest recoiling .32 pocket pistol on the market, so that means a .22 or a .25. She isn't happy with having to lower the hammer between chambers on a NAA mini-revolver, so that means a small semi-auto the only option.
I figure the likely best choice is here:
http://www.taurususa.com/products/gunselector-results.cfm?series=SF1The DAO trigger - which I understand to be relatively light - and tip-up barrel should make it very easy for her to use. Most people I know who own these guns like them.
My question is: should I go with the .22 or the .25?
In the .22's favor:
1) I have a bit more confidence in the ability of the .22 to penetrate to the vitals.
2) Inexpensive practice ammo.
3) Can use CCI Stinger or Quick Shock ammo.
In the .25's favor:
1) One more round of magazine capacity, which could provide one more critical chance to neutralize an attacker with these less than optimally effective calibers.
2) Some users seem to believe that the .25 is more reliable in these small autos. If true, that, by itself, is the deciding factor.
3) The ability to use Magsafe ammo.
So, what are all of your thoughts?
Is the .25 more reliable than the .22 in these small pistols?
Would going with something like Magsafe or Quickshock improve the chances of hitting something vital, or give up too much needed penetration?
Is one more effective than the other? If the .22 is more effective, is the difference worth giving up one round of magazine capacity?
Other gun suggestions are also welcome.
Thanks in advance.
