M1 Carbine Stripper Clips

[M94/14]

You can re-use them indefinitely if you carefully pinch together the bottom ends of the rails slightly. I've found this little bit of pinch is usually enough to hold that last round from falling out of the clip when the tab has been broken off. I use a needle nose pliers and pinch just a bit at a time, then try it with a round to see if it holds, and adjust more, or less from there. When you have it right, the round will just slightly snap past the end of the clip, and then move freely up towards the top of the clip.
