Carmelo, You like big guns. The M9 will be a fan favorite. I like the trigger pull and set up on the HK P30. M9 has very long pull and even on single action which is nice is still very deep against back of trigger guard. Should try them all at nearest rental range.

Beretta M9 Hands down. Much more accurate and my Walther has issues.

I like the M9 to me it just feels better I suggest that you go to a local gun store/range and see if you can handle /rent them the pick the one you like the best
