View over the sights of a
Feinwerkbau model 40 target pistol
This view over the open sights of a pistol shows what the shooter sees when on aim. Many people do not know how to use 'open' sights (sometimes called 'iron sights') on pistols and rifles and this photograph gives a reasonable impression of how they are intended to be employed when shooting at a round aiming mark (the grey disk above the foresight).
The first point to remember is that the eye should be focussed onto the foresight, so that it is sharp and clear, this inevitably means that the rear sight and the target itself will be out of sharp focus and appear somewhat grey. Secondly, the foresight post should be central in the rear sight gap and the top of the foresight level with the top of the rear sight. Thirdly, the top of the foresight should be held under the aiming mark by a distance roughly equal to the width of the foresight. This gap is to give a degree of isolation from the aiming mark so that tremor (wobble) is less noticeable to the shooter and therefore less off-putting.
