101 magazine releasing
Thu Nov 8, 2018 09:57

Hello Mat,

Your description of being "silver" confirms that unless blue has been completely buffed off, it's a cadmium plated magazine. "rust" at the release, would indicates at the very bottom at the foot, which shouldn't affect releasing much. The critical part it at the top, starting just barely below the button on the left side. That button is what you move down to continually load the ammo, and it also operates the "slide lock" when the last round is fired or loaded into the chamber.

From that button up is the part that goes into the rectangular opening in the frame when inserted. The tolerances is very tight as to whethwr it inserts easily or not, if tight, it's also difficult to release it's grip on the magazine for "dropping out" or even pulling out. so the real critical area is the top-most 1 inch forward side. I've gotten some that were so swelled from rust that the top spot weld was broken, and a razor knife blade easily slid between the shell halves there. Others just had a large area of swelling, and though you could "beat" one in, you had to beat it out from the top as well.

BTW, a great way to clean magazines is with #0000 (four ought) steel wool.

I've seen where some people used a "polishing wheel" found at welding supply stores for small 4 1/2" angle grinders on both sides at that top inch, to effect insertion ease. However, that removes the cadmium plating, down to base metal, and that's prone to rust just from the humidity in the air. touching up that area (with a cold blue (like Birchwood Casey Perma Blue Paste Gun Blue) could slow down that rust process. But the metal is now thinner, an will eventually just fail anyway.

Best solution for being able to fire your gun with ease and have the magazine work properly is to just get a slightly later version magazine that's Blued, with blued steel follower. You can find cadmium plated ones that will function well, but risk getting a "junker" are two in a batch. I'd recommend finding ONE that works swell, then not use it, just to keep the gun original. Actually use the blued ones. Again, get the Hi-Standard marked ones, they'll give you better service in the long run.
