Most folks agree that for the majority of defensive handgun situations, a two-handed eye-level shooting stance will yield the best results. For anything much beyond arm’s length, two-handed eye-level shooting will give the novice, part-time or even the experienced shooter a higher percentage of good hits, especially when under stress. However, there are a significant number of defensive situations where only the gun hand can be placed on the weapon. This could be because your attacker is so close that you cannot raise the weapon up to eye level. The other hand must be used to fend off the assault or block his weapon, or it could have been disabled in the initial attack. Your other hand could be performing another task, such as pushing your spouse or child out of harm’s way, or clinging to some handy solid object for support.
If you must use one hand only it is still best to get the weapon up to eye level. Even when shooting at maximum speed, train yourself to find that front sight. At short range, say inside 20 feet, if you see the front sight fairly centered on your target you should get a good hit. If your attacker is so close that extending your arm might put your weapon in jeopardy of being deflected or taken away, keep it back and out of his reach. A little practice in unsighted one-handed point-shooting is well worthwhile. Just keep the range short, zero to 10 or 15 feet. Remember this point shooting is generally effective only when the range is up close and personal; otherwise, get that weapon up to eye level.
