To be absolutely honest , they are different guns, not a replacement or up or downgrade.

I have a 110 , and have encountered NON, of the problems that folk keep coming up with.
The pellet speed dipped a bit , but a quick barrel clean and it was back up to as new performance.
It lives in the boot of the jeep, so is not exactly a pampered toy.
It is used for plinking and hunting , and has never leaked or broken in any way.
So I can only say as I find.
I have had 3, 100's and all of them leaked .
They were brilliant when they were working though.
