% of .22 "knock down power"...I need ideas.

20g shotgun with low recoil buckshot!

There is absolutly nothing wrong with a .22. Im not a pro but I can work numbers. If you have decided to shoot some one to kill then you might as well go all the way. Empty the clip. The .22 may not be strong with only one round but 10 rounds is something else. Simple as that

I'll 2nd the 22 mag suggestion, but, as was mentioned, it is a revolver round anymore. I've got a Grendel P30 that's a blast to shoot (30 rounds) and has never failed to function but is hard to trust your life to it and besides, Clinton killed it with his ban and now if you can find one, they are expensive. But, its a dandy cartridge.

I have a female cousin who lives just enough distance away that the only communication we ever get is via internet & phone, but I am known as the firearms enthusiast of the family so she has come to me with a recent problem...Her husband has recently flown the coop and she is left to spend many a night alone, awake, as the changes have left her without desire to sleep at night and she really wants some home protection in the way of a firearm.

We have spent alot of time going over the differences between an Auto, Sa, Dao and she has gone to her local range/shop and fired a few different autos, and has decided that she does like the ammo capacity of an auto, but simply cannot find a .9mm that feels right in her hands, claiming that they all feel too big and top heavy...I also muse that she is anticipating recoil somewhat.

Before now, I would never in my wildest dreams suggest a .22 for home protection, but after the extensive conversations I realize that what she really needs is range time, long comfortable sessions where she can become cozy with her weapon...Like me, she has small hands...Albeit small, she is very altheletic so I really wanted her to utilize that strength and go straight for a larger caliber, but it aint happening.

I've suggested that she go try out a Browning Buckmark and a Walther P22 next. I know that she will eventually upgrade to a larger caliber and either trade the .22 in on it or have two guns around the home, but at this point I really think the slender, controlable size and comfortable recoil of those pieces is what she needs.

OK...Finally to my question!

How would a guy make a fair mathematical comparison between a .9mm and a .22 in terms of how it will affect the bad guy? Is there a way to look at the velocity/bullet mass differences and actually come up with a figure that you can sit down with and say for example "Hey you are hitting this guy with, say, 20% of the knockdown power that you could expect to get from a .9mm"?

She would certainly be using Velocitors or a similar high velocity cartridge, but she posed the question about comparrison precentages and although I was proud that she even thought of it, I didnt have a clue how to answer her.

Thanks in advance

First Off Handguns dont' knock you off your feet. There are two important factors to stopping a threat quickly. Peneatration and Trauma that causes fast bleed out. This is why a handgun is considered a secondary weapon. Having said this: Its always good to have your cousin use what she shoots well with and feels best in her hands. The problem with semi-auto's for females besides recoil is manipulation of the slide to cycle a round. Beretta makes a flip top 84 Cheetah in 380 or they used to that women love. I also reccommend the Browining Hipower, my wife shoots that one the most and she can rack the slide easier than with about any other pistol and it fits her hand. The 22 situation will definatley kill and debilitate or maim no doubt but if she goes to that she has to be willing to pull the trigger until the gun is empty to have any stopping effect, ive seen too many women that shoot once then throw down the gun like a kid. Not to stereo type) Good luck
