I don't like either option. I concur with the Ruger being suboptimal at best, due to a very difficult to work trigger. I also think the G42 is large enough that a petite person with fitted clothes might find it hard to conceal.
Having said all that, I think we should award the Internet to flux for his auto-correct on his computer/phone turning Ruger into "Rubber." Because a rubber pistol is always safest for AIWB or pocket carry...
