Walther PDP vs Walther Q4 SF. Is the Q4 SF really twice as good? because it’s about double the cost.
It's almost double the cost because it has an all steel frame that has to be machined instead of molded. At around $1,500 the build quality, fit and finish is just as good as my Wilson EDC X9 which is almost double the cost. The machining on this pistol is second to none. It really is that good. Because of it's all steel construction it is on the heavy side though.. The only thing I did was change the trigger for an Overwatch Precision one. Not that there's anything inherently wrong with them I just don't like the feel of plastic triggers on any gun. If there's an all metal or aluminum one available I change them. If not it's something that I have to live with.
