I got to go shoot this for the first time yesterday. Overall, I am impressed with how the gun handles. I did not find the recoil impulse to be especially snappy as I have heard people say on YouTube. However, context matters and I was shooting my 10mm during the same range visit. It is possible that I did not notice the increased muzzle rise and recoil from the Walther, because the recoil and muzzle rise of the 10mm is significantly more.
So far, I like everything about the gun save for one thing, sights. The sights are not bad per say, but I would not classify them as good either. The problem stems from two factors for me. First, the front sight dot is small and I found it a little difficult to see clearly. Second, I am not a huge fan of three dot sights. I would be much happier with a sight similar to what came on my Springfield XDM Elite. That said, not liking the sights is a moot point for me, as I intend to install an optic once the optic plate finally shows up. I have a Vortex Venom sight I will install. This sight requires a little filing to fit into the recess of the PDP. Nothing that cannot be accomplished in just a few minutes with a flat file.
When filing the sight to fit the mounting recess, I was careful to check for fit between each pass of the file. As a result, I have an optic that fits the recess perfectly. This relieves my concern about the lack of lugs on the slide to absorb the brunt of recoil. The screws will hold the optic down and the body of the optic is in contact with the slide. We shall see how this works out.
I got an email last week from Walther that my optic plate order had been sent to the warehouse for shipment, but they said it would take 14-21 days depending on the shipping carrier. I have to say that waiting nearly a month to be able to mount an optic on an "optic ready" pistol is disappointing. I would gladly pay more to have the most common plates included with the gun.
