Bought my wife a new H&K VP9 and it stove pipes or FTF on every shot when she shoots it. When I shoot it I get Stove pipe at least once in 6 shots. I have disassembled and cleaned it and lightly oiled it in the prescribed areas. Same result. We are shooting Federal 115 grain FMJ. Same result with either magazine. She shot several magazines with the same ammo in her Glock 43 with no malfunctions. This gun is brand new. We also have a brand new Walther PPQ M1 and it functions perfectly for her. Any suggestions appreciated.
