My love of DAO pistols is one of the reasons that I am so fond of pistols manufactured by Kahr Arms. The Blauvelt, N.Y.-based company offers some of the most practical, easy to conceal DAO pistols on the market.
Stage-Free
The Kahr's light, stage-free trigger stroke is accomplished by means of a system in which a trigger travel of approximately 18mm rotates a cam, which then unlocks the spring-loaded striker safety, and draws the striker to full cock position before releasing it to fire the pistol. A striker block prevents the partially cocked striker from moving until it is deactivated by a complete trigger stroke.
There are no external safety devices on Kahr pistols. This gives the weapons a smooth, snag-free exterior, a very positive feature on a handgun meant to be drawn from concealment.
Breech locking is accomplished by the barrel hood bearing on the front edge of the ejection port. Upon firing, the slide moves rearward and a cam on the barrel lug pulls the barrel down, unlocking it from the slide, which continues rearward, extracting and ejecting the spent case. A recoil spring, located on a full-length guide rod under the barrel, pulls the slide forward, stripping a round from the magazine, and chambering it. As the slide goes into battery, the barrel and slide are locked together by the barrel hood moving up into the ejection port.
