Well, the difference is of course the model. The P5 has some similar "lines" that the P99 does. Especially in the slide area. The P99 is the only polymer gun that Walther makes. You can go to Walther's web site www.carlwalther.de and check out all the different models that Walther currently makes. Or do a search for Walther handgun on the web.[b said:Quote[/b] (Bruz @ Dec. 30 2002,11:07)]What is the difference?
