These look decent.
I once had a Walther P-4 which looks just like a P-38 (or P-1) but the slide was totally different inside.
I then had a P-5 which was mechanically similar to the P-4 but had a much more modern look and a barrel which was, I think only 3.5 inches which is too short imo.
I will say the P-5 was a good shooter tho.
