L5p Derringer

For anyone that ordered a Banks Derringer; once you get it and have it installed will you please post results of performance gains. I'm sure there are a lot of us wondering how well it works. Thank you in advance

I just donít know if Iíd really trust anything like it (stealth and scorcher too), but if anyone could pull off a viable option itíd be Gale. He has been so hands on with the L5P with his military contracts. Iím interested to see real world results and will probably wait about a year or two after release to see long term use results.

I'm all about more power, but a 400 horsepower diesel seems pretty stout to me.
