By the way, for those who would like to have one more round in the tubular magazine ( 6+1 instead of 5+1). Just cut few coils off the magazine spring (usually 4 1/2 coil).
and you'll be able to put 6 in there . I was told that the only reason it is limited to 5+1 is
because of import restrictions. It will function perfectly, if not better , with the shorter spring.
