I recently purchased a Walther PDP 4.5" barrel. I decided to compare the velocity I get from my handloaded 115 grain XTP bullets between my Glock 43x and my new Walther. Now the Walther has an extra 1.3" barrel length and I saw a 100 fps change in velocity. These are loaded with CFE pistol and below published max charge weights. The Glock was getting 1180 fps average and the Walther was getting 1280 with the same ammunition. This lead me to wonder what some 9mm+P would do. With Speer 124 grain +P loads, my Glock gets 1215 fps. The Walther got 1360! Maybe I am off base, but that is moving pretty darn fast for 9mm and 124 grains.
