They look like they've found great home on your pistol-glad I was able to help (and accurately tell my wife that occassionally I do divest myself of things I don't use...)
It's guaranteed to shoot more accurately and faster. It also gives you the capability of leaping over tall buildings in one mighty stride. You and your FEG will leap to the pinnacle of Hi Power performance....
Seriously, enjoy. It looks great.
Best, Jon
