My ac44 p38 ocasionally jams a shell during fireing! One quarter of the unfired shell protrudes from the breech, and it appears the signal pin is on top of the unfired shell with the next shell in the magazine pushing on the part of the shell not seated in the breech.Any thoughts?
Thanks,
T.bone

t.bone, please keep up posted on what you find. It's not often that P.38's experience the trouble you describe; I'm interested in helping you through this if necessary. We'll get it running!

Troubleshooting P.38 magazines:

Note that it is possible to insert the magazine spring four different ways. Only one of them is correct.

The spring is installed with the short coil upward, supporting the roof of the folower; the second (full) coil supports the lower step of the follower. Observe this relationship with the spring and follower out of the mag body. Note that the spring can be incorrectly installed upside down, or backward, or upside down AND backward. When reassembled, toggle the the follower with your thumb to check for excessive fore-and-aft play; the follower should fit closely enough not to “nosedive” from forward pressure.

Best and quickest way to test a magazine is to try it in a gun known to function correctly. Conversely the way to eliminate the magazine as the source of a malfunction in a given pistol is to substitute a magazine known to function correctly. However, if you have neither another magazine nor a spare P.38, try the following:

Visually check for magazine lips for bent or damaged lips. The inside width between lips of a new magazine is about 8mm. (The drawing calls for 8.0mm +0.2) After some use it will spread a little, to between about 8.15mm to 8.25mm, but it’s still serviceable as long as the top cartridge is presented more or less parallel to the angle of the lips.

Dismantle the magazine, wipe out the inside until it’s shiny and look through it (like you would a shotgun barrel) for dents or distortion, especially at the feed lips end. The walls should be straight, not convex (looking from the inside). Insert the follower without the spring and feel for smooth movement up and down. If it sticks anywhere, discard the magazine. If there are any cracks around the lips, especially on the back, discard the magazine. Any mag with plier marks on the lips indicating that it has been tweaked by some prior user is suspect, and should be stripped of usable parts and thrown away.

One other possibility, much more common in late WWII P.38s than in postwar guns, is a misshapen or mislocated seat in the frame for the magazine catch trunnions, or mislocated or damaged trunnions. In such case the magazine, when latched, will have excessive vertical play. This allows random presentation of the top cartridge and may produce feeding malfunctions. This is sometimes aggravated by some shooters who grip the pistol with their free hand under the butt, putting upward pressure on the magazine.

I may have sent my reply to the wrong site!Oops!What I said was " my luck it would be an oddball problem" Will check my magazine springs ,although I do have a couple of them and the jam occurred w/ both! I did field strip and clean w/ Hoppes"9" I do have a brush that came w/ my post war cleaning kit that I will use on the breech. Will not have a chance to test fire for a couple of days though so bear w/ me for results!
Thanks,
T.bone

Still have not fired after cleaning:( have not had time! Did see a you tube video by Responsible Citizen 64 that showed a"double feed jam" as he called it that looks similar to my issue!

I realize this is way late, but sure sounds to me like a problem with extraction. Replacement of the extractor, extractor spring, and plunger -- all at once -- might fix it. Otherwise a good gunsmith might need to be consulted.
