I am considering a Glock 42 for conceal carry. I will be carrying 4 o'clock owb. Any input would be appreciated.
It's an excellent choice for CCW. With modern bullet design, 380 ACP is getting a lot better. For some "Bigger is always better" guys, they'll pick the 43 because the size differences between 42 & 43 are very little. (But not everyone wants a 43 because if you shoot them side by side, the S&W Shield 9 is a lot easier to shoot.)
