Troops with the semi autos were issued 12 stripper clips, and 1 magazine in adition to the one already in the mag well (a spare if the regular one broke, got lost ect), this was how troops loaded their SVT/AVT, G41/43s, sripper clips....the magazine was really only supposed to be removed for cleaning, and the magazine latches in the magazine well wore out easily, removing the magazine on any early semi auto rifle not meant for box mag reloads would result in mags not feeding ammo properly and even falling out because the latch doesnt catch.... same with Lee Enfield rifles, I dont recall ever hearing about British troops removing the mags in their rifles to reload (and I've interviewed plenty of veterans over the years)...it was all via clips. Troops would scavange extra mags in the field however, because they wouldnt likely live long enough for mechanical wear&tear to happen......I think spawning with 12 clips, and 1 spare mag should be standard, and be able to pick up spare magazines from other SVT/SVTs found on fallen comrades would be a good option
