I honestly think "Trying" them in store is no better predictor of user compatibility than lying down in a mattress store to see if it's right for you.
I ran px4's my whole life and i regret not getting a glock because it feels much better, fits my hand snugly, well weighted, and the recoil is just right.
Get into the game, try something either rented or borrowed. If you like it, get what you want and trade around if you want to try something else.
