A stovepipe is basically an extraction without proper ejection, and can be caused by several things. Does it only happen on an empty mag, but rarely on a loaded one? Then it's probably the mag - the position or angle of the feed lips may be slightly out of spec and interfering with proper ejection. The fact you have two P238's to play with allows for some diagnostics. Try the following:
Switch the magazine between the working and malfunctioning gun. Test the malfunctioning gun. If the problem goes away, that's the problem. Otherwise switch the mag back and:
Switch the slides, fully assembled. If the problem doesn't go away, its most likely the ejector is out of spec. Otherwise switch the slide back and:
Switch the recoil spring. If the problem goes away, it's most likely the problem. Otherwise switch the spring back and:
Switch the barrel. If the problem goes away, it's most likely an out of spec chamber. Otherwise, it's most likely an out of spec extractor/spring.
Those are the most likely culprits, and a how to identify them. Generally, you want to observe the absence of a malfunction for 10x the number of rounds that it tends to occur in. In other words, if on average every 10 rounds you get a stovepipe, you want to shoot at least 100 rounds malfunction free before determining that the malfunction went away. Here's what to do with this knowledge:
Mag: Throw it away and buy another one.
Ejector: Replace it.
Recoil Spring: Replace it.
Barrel: Get the chamber polished.
Extractor: Replace it and it's spring.
Any competent gunsmith or armorer will be able to replace the extractor/ejector or polish the chamber for you. Hope this helps!
