Guide to Kahr Magazines
Comparison: PM Series vs CM Series

The CM Series, which debuted in spring 2011 with the CM9, takes the value priced features from Kahr's CW series (3.6" barrel, 9 mm, .40 S&W and .45 ACP models) and incorporates these features into a smaller 3" barrel package. The CM4043 has the same external dimensions as the PM4043, which make it ideal for concealed carry by licensed civilians and law enforcement personnel.

The CM4043 is chambered in a .40 S&W caliber, has a 3.1" barrel and an overall length of 5.47", with a height of 4.0". The pistol weighs in at 15.8 ounces plus 1.9 ounces for the stainless steel magazine. Differences between the CM models and PM models include: the CM4043 has a conventional rifled barrel instead of the match grade polygonal barrel on Kahr's PM series; the CM slide stop lever is MIM (metal-injection-molded) instead of machined; the CM series slide has fewer machining operations and uses simple roll marking instead of engraved markings; and finally, the CM series are shipped with one magazine instead of two magazines.

The CM40 boasts real sights, which are drift adjustable in the rear and a pinned-in polymer front sight featuring a white bar-dot configuration. Finally, the slide does lock back after firing the last round - another feature missing on a number of other value priced compact semi-auto pistols.

The CM40 slide is machined from solid 416 stainless steel with a matte finish and is only .94 inch wide. Each gun is shipped with one 5 rd stainless steel magazine with a flush floorplate. Magazines are made in the USA, plasma welded, tumbled to remove burrs and feature Wolff Gunsprings. The magazine catch in the polymer frame is all metal and will not wear out on the stainless steel magazine after many uses.

Just like the CM9, the new CM40 will include all of the great features that make Kahr pistols one of a kind. Kahr's seven patents result in benefits not available in other compact semi-autos on the market today:
- The black polymer frame features patented 4140 steel inserts molded into the frame in the front and back for added rigidity and strength, which can withstand firing thousands of rounds.
- Kahr's incomparable cocking cam trigger system employs a patented cam to both unlock the firing pin block (passive safety), and complete cocking and releasing of the firing pin. The system provides a "safe-cam action" and unbelievably smooth double action only trigger stroke, fast to fire in critical defensive situations. Many lower cost compact semi-autos on the market today do not have firing pin blocks in their design.
- Kahr's two patents covering the offset recoil lug and the trigger bar attachment allow Kahr's barrel to fit lower in the frame, and since there is no hammer, the shooter's hand is further up the grip resulting in less felt recoil and quick follow-up shots.

Kahr offers the CM series at a great value price, but did not compromise on the features, accuracy or reliability found in all Kahr pistols.
