Shootall,
If you think the 32 = 25, you are only foolng yourself. If you think the 38 in a 2" barrel will not need just as many shots to stop a threat as the 32, you are fooling yourself. If you think that you can carry ammo and reload a 38 as fast as a 32, you are fooling yourself.
In 151 actual shootings the 32 Silvertip stopped the attack with one shot 66% of the time.
In 305 actual shootings the 38+P LHP 158gr (snubnose) stopped the attack with one shot 67% of the time.
Now it has been argued, and rightfully so, that those figures do not account for all the times people were shot more than once. So while these figures DO NOT indicate that either bullet will work 66% of the time, they CERTAINLY indicate that neither bullet is going to work ANY BETTER than 67% of the time (including your 38 round). It also CERTAINLY indicates that in a head to head comparison by the same criteria from 456 ACTUAL SHOOTINGS, the 32 silvertip and the 38+p 158gr LHP FROM A 2" BARREL are dead even in effectiveness (38 effectiveness goes way up from a 4" barrel.)
I am sure your wife can shoot the 38, but I am also sure that you must be just as accurate with a 38 as you are with a 32 (151 shootings testify that the 32 is NOT a head shot only proposition) and that the 32 will do it faster. I usually carry a 40S&W or a 45acp in a compact package. These have more recoil than the 38 snub and considerably more than the 32, but the difference is that when one of those hits it will be considerably more effective than the 32 while the 38 snub will only be "as good" as the 32. If I go to something with more recoil I am going to get more effectiveness. If it is not more effective, why put up with the recoil? THAT is why I don't carry a 38 and I do carry a 32 instead.
I too have times when I simply cannot carry my larger gun or when I feel I need a backup to my larger gun. In those times, the 32 is easily as good if not a better choice than the 38. Carry what you like, but don't fool yourself about the effectiveness of what you carry. That can get you hurt.
My wife can dump 7 rounds of 32 on target (or targets) AND RELOAD faster than your wife can empty her 5 rounds of 38 and be out of options.
Be safe out there,
