I am looking at another 9mm. I am curious about the difference between the HK VP9 vs Walther PPQ. I am also looking at Ruger SR9C. I know that the SR9C has an excellent trigger and can be used as either compact or range gun. I know that the two German madel pistols have a great reputation for quality, and also have good triggers. However don't know much about either. Thanks for inputs and experiences (pros and cons)of these pistols.
