I have had a M141 Remington in .35 Remington for several years. It has one peculiarity (feature?) that I don't know whether it's normal with this rifle or not as this is the only M141 I've had any experience with. After loading the magazine the first pump (action cycle) fails to feed a round about 99% of the time. After that the rifle functions flawlessly. I also notice that the rounds in the magazine are farther back after the initial pump. Is this normal with this weapon?
