Glock 42
My most often carried pistol when I am off duty is my GLOCK 42. It fits all my needs with reliability, accuracy and compactness. It replaced my WALTHER PPK for off duty carry.
The GLOCK is about the same size, but lighter, has a simpler operating system, the SAFE ACTION vs. TRADITIONAL DOUBLE/SINGLE ACTION trigger.
Also, the GLOCK seems to be nearly impervious to rust.
Plus my GLOCK 42 is in .380ACP, while my WALTHER PPK was a .32ACP. Funny thing is that the recoil I perceive is about the same.
Still, every once in a while, I carry something smaller like the BERETTA Tomcat. It is just more concealable that either the GLOCK 42 or PPK.
All, good guns and I am very happy with them.
