Hi
Take your time and don't rush into a purchase.
I would not want to buy a pistol which I had not been able to use even if it is brand new.
A fundamental part of pistol shooting is trigger control. The trigger has to be flawless in its operation. I have shot many different pistols including both Steyr and Walther (as well as Anshutz, Feinwerkbau, Benelli, Morini etc). Both the LP400 & LP2 have mechanical trigger units. My Steyr pistols all developed variability in the 2nd stage trigger weight as they got older. I didn't rate the LP400 trigger unit when it 1st came out. However, they have made improvements in later models.
The balance of both pistols is very good.
The Benelli was a brilliant gun for the money but rare & difficult to get serviced in the UK.
My Feinwerkbau was also a great gun with a superb mechanical trigger.
I now favour Morini as it has, in my view, the best trigger unit (the electronic version).
Overall it is a close call as both guns you are looking at should hold very tight groups when batch tested and are likely to be very consistent and accurate.
Good luck
