I have a 640. Probably much the same as the 340 except for the color. I can compare with my Keltec P11 for the use of both as pocket guns. The 640 is a little too bulky for a front pants pocket carry IMHO. The P11 sits very well and doesn't print with a pocket holster. The 640 works well in a coat pocket or even in a cargo pocket as long as it doesn't swing around too much when walking. Hopes this helps. Mine is .357, although I doubt that a .38 model would be much different for this comparison.
