I work in a gun store and I get to fondle guns all day, everyday.
When a customer comes in with no clue about what duty-size striker to buy, I show them everything. After taking the customer "around the world", the guns I sell most are Glock 19/17/45, Sig p320 and Walther PDP.
If I was looking at another of this type of gun, I would go with a full size Walther PDP. It really is a nice gun and it practically sells itself. I have sold 5 this week.
fyi....Smith & Wesson is the brand of gun we send out for warranty repair the most often. And I mean a LOT more often than any other top tier brand.
