I do, once in a while
There is shoot, and there is shoot....
No, the old alloys aren't as "good" as the ones today, but that only matters as a point of comparison. Otherwise, it means squat. 4 point carbon steel then is still 4 point carbon steel today.
And yes, German quality control went down in the final years of the war. Some things were deliberate (less work on the finish), and some things were the result of production pressures, degradation in the quality of the raw materials available, and even sabotage.
I won't disagree with anyone who won't shoot their WWII era guns, because there is no replacing those originals. I do disagree with those who tell me I shouldn't shoot mine, simply because its MY gun, not theirs. And there is shoot, and there is
shoot....
I'm no P.38 expert, I didn't even know the gun ejects to the LEFT, until I got one of my very own. SO what is, and isn't a design weakness in their construction, I leave to the
experten.
What I can tell you is that guns designed (and built) 70+ years ago were not made with the expectation that they were going to be fired a lot. And by a lot, I mean the way some people shoot today (round count). And the thought that they might be fired with overpressure ammo seldom, if ever crossed the designers minds either, I'm willing to bet.
Original specs for the 9mm Luger were a 124gr FMJ at 1050fps. By WW I they had improved the load to a 115gr bullet at 1150fps. What was the original life expectancy of a P.38? I don't know, but I do know the original GI 1911 was 5,000 rounds service life. It is really rare for a 1911 not to manage that, with correct ammo, but it has happened. Most of them will go well over that, of course.
Broken slide on a wartime P.38 after
only 2,000 rounds? Pity. Sounds like you got a bad one. It happens. The trouble with stories like this is usually the only info we hear is the gun type and round count, and what the failure was. All good things to know, BUT, not enough info to draw a really valid conclusion, other than for that individual gun.
A 1945 production P.38 and
only 2,000rnds of modern 9mm +P+, and I wouldn't be surprised at a major failure. A gun built before the Germans began losing the war, and 5,000rnds of the
proper ammo, I'd be surprised if it suffered a major failure.
I have an AC 42. I shoot it once in a while, a couple boxes of ammo a year, maybe. I fully expect that gun to outlast me, at that rate. If you want something to run hundreds of rounds a month through, month in, month out, get something else.
Might I suggest something in the new lines of combat Tupperware?
