I have and enjoy both...prefer the DA/SA of the earlier guns. The pull on a 39-2 in DA is similar to but heavier than my revolvers and I don't have any trouble with the first shot. Reset is outstanding on Smith's pre-fantastic plastic autos...if you haven't paid attention or had a chance to shoot one you may be surprised.

I'm a firearms enthusiast who's hobby happens to have self defense applications so I approach it from that angle. I will carry any of my guns and have confidence in my ability with both traditional DA or striker fired. Spend enough time behind most any gun and you can be proficient with it.
