Two more brands to consider: SIG SAUER and Kahr Arms.
Kahr is a relative newcomer to the gun scene. Founded by the son of the man who headed the Unification Church (the “Moonies”), Kahr makes small and medium-sized handguns with steel or polymer frames. They’re all single-stack, striker-fired designs.
SIG is . . . SIG. Their guns used to be designed in Switzerland and made in Germany. Nowadays SIG make slides and other components in the United States, as well. They have a reputation for quality and precision. They were late to the polymer frame pistol party, but have been making up for lost time.
Same method as before: every review in Gun Tests magazine back to 1996. A gun’s judged as “broken” if it stopped working, shed parts, or physically disintegrated in some way. A gun classified as “unreliable” if it had failures to fire, feed, extract or eject that were not attributable to a documented problem with the ammunition. An obviously defective part like a single bad magazine would not render a gun “unreliable” if the manufacturer’s regular magazines worked when the bad magazine was replaced like-for-like.
Not a huge dataset of Kahr tests to draw on. Kahr specifically states in their owner’s manuals that you must fire 200 rounds through their guns before you can consider them reliable. In 4 of the 9 guns tested, there were reliability issues during the break-in period. In each case, however, the guns ran perfectly after the break-in was completed.
Four of the 36 centerfire SIG pistols tested were unreliable: a P239, a P226 (during break-in period) a SP2340 (during break-in period) and a P250.
Three of the 39 SIGs that were tested were .22 target guns: two Mosquitos and a Trailside Target. Both Mosquitos were unreliable, and one of them fired when the gun was out of battery. The Mosquito has a troubled reputation, much like the Walther P22.
