I believe it was Jerry Miculek who personally suggested to Smith&Wesson to produce an airweight .22mag recently; the new model 351pd is the result, it is very light at 10.6oz, as for performance Guns & Ammo Handguns recently did an article in the Oct/Nov 2005 issue here are the results, test gun for both 22lr & 22mag calibers was a 2" barrel NAA Black Widow with interchangable cylinders, test gun 25auto was Baby Browning 2.1" barrel, and test gun 25naa(32auto case necked down to 25 caliber) was NAA Guardian 2.185" barrel

25naa___________bullet_____________velocity

Best performance for penetration and expansion in 22lr was Winchester Power Point 40gr HP and Remington Yellow Jacket 33gr HP although most were unreliable, in 22mag the clear winner was CCI Maxi-Mag TNT HP which expanded like a premium self defense round every time with good penetration, none of the 25auto rounds would expand properly, and the 25naa performed reliable every time.
