A retired CSM (82nd Airborne, 3rd Infantry) I knew had 3 personally owned handguns, a Walther P38 (Uncle's War Trophy) he got permission to carry in Korea and Vietnam, a S&W M29 (held for evidence after shooting a home invader) and a P88 he bought to carry while his M29 was held. In his opinion it was a very well made pistol and a worthy successor to the P38.
That and the few times I examined it are about all I can tell you. It was very accurate according to the SM.
