Is it for concealed carry or home defense or just for fun? Concealed carry generally go with the smaller frame size for solely home defense you can get away with a larger frame/longer barrel for better accuracy. If you can find a range where you can rent the exact, or as close to as possible, model you’re looking at getting it will give you a better feel. When I was looking at purchasing my first semi-auto pistol, for concealed carry, this is what I did and so glad I did. The 9mm S&W jumped around in my hand and I had a hard time controlling it. The 9mm Glock was perfection for me. I have since “upgraded” to a .40 Glock that I find comparable, in comfort of shooting and accuracy, to the 9mm.
And for his last birthday I got my husband a Beretta PX4 Storm in .45 auto that is a real pleasure to shoot, but in my mind too large for concealed carry.
My wife’s carry gun is a PX4 in .45.She found a very nice purse with an internal holster.Some mugger is going to end up with a big surprise.
