Can't tell you anything about the 42 but I had the old 24v which is what the 42 is based off of I imagine. Killed a ton of squirrels and rabbits with that little combo. I gave it to one of my cousins kids for a Christmas present some years ago. Always went bang and honestly, for what it was, it was an accurate little rifle. If that plastic stuff 42 shoots as well as my old 24v you wont be disappointed in any way.
