The AMT Hardballer is a series of pistols that are part of the 1911 platform (based on the .45 ACP M1911) made by Arcadia Machine & Tool (AMT) from 1977 to 2002. [1] The Hardballer was the first entirely stainless steel 1911 pattern pistol. [2] Other features included adjustable rear sights and a lengthened grip safety. [3]
The greatest adjustment of focus (relatively more ocular muscle contraction) is required to view shorter distances, such as the gun's rear sight. In the modern technique, the shooter is taught to focus on the front sight of the pistol and align it against the target, ignoring the rear sight for quicker aiming and minimal physical requirements.
In ranged weapons such as firearms and artillery pieces, the act of sighting in or sight-in is a preparatory or corrective calibration of the sights with the goal of having the projectile (e.g. bullet or shell) placed on a predictable impact position in relation to the sight picture.
Comparison of milliradian (mil) and minute of arc (moa).. Since adjusting the point of impact to match the point of aim is relatively simple with any type of adjustable sights, the primary goal of accurizing is to increase the precision of the firearm, which is generally measured by looking at the dispersion of a number of shots fired at the same point of aim.
With tangent sights, the rear sight is often used to adjust the elevation, and the front the windage. The M16A2 later M16 series rifles have a dial adjustable range calibrated rear sight, and use an elevation adjustable front sight to "zero" the rifle at a given range. The rear sight is used for windage adjustment and to change the zero range.
The windage adjustment is intended only for the initial sighting in procedure of the C79. Elevation adjustments are made via a rotary knob and are adjusted from 200 to 800 m. To bring the sight to a proper elevation zero, a small "gate" must be elevated which disconnects the elevation cam and one mil clicks can now be made.
The Kimber Eclipse is a model 1911 semi-automatic pistol chambered for the .45 ACP and 10mm Auto cartridges. It is made by Kimber Manufacturing in Yonkers, New York . There are several models of Kimber Eclipse, of different sizes and with different combinations of features.
It is available with fixed or adjustable sights. The pistols were originally made with the 2nd trigger guard, which has an elongated, oval shape (see photo); in 1992 the frame was redesigned with the shorter, rounder 3rd trigger guard. [1] The model 1006 was the first in the S&W 1000 series of third generation semi-automatic handguns.
