Ya know those things throw brass to the LEFT, don't ya?
The P-38 is my go to gun when the kid on my left is pelting me with .22 brass at the range!
For just shooting a p-38, the post war P-1 (same gun, new designation) are probably the best value. Later alloy frame guns might be even cheaper...pardon, less expensive.
Read a 5500rnd "torture test" done back in the 70s with an allow frame P-38. After it was all done, the only wear was on the finish where the parts rubbed. So, I'd say an alloy frame P-38 should last a while as a casual plinker.
