If you're ordering online and you want the best odds of getting a rifle with a good bore, get the M44. Many of the ones flooding the market recently were either unissued, or saw little use and were arsenal reworked, slathered in cosmoline and put into huge crates and stored in a massive warehouse along with the Ark of the Covenant.
The M38s were put in the same warehouse, but they saw a LOT more use before they got there. Think "Stalingrad". Some of them are good. Some of them are beat straight to heck. If you're ordeirng online, you're never really sure which you're gonna get.
That said, the M38 is a better handling gun. It also recoils worse than the M44. No free lunch.
