Thanks for taking me to the range man! The Mosin was sweeeet!
Glad you enjoyed yourself!
I've never shot the M38, so I don't know for sure. I don't recall thinking that extending the bayo helped the balance of the M44 that much though. I had read at one time that for the best accuracy the rifle's bayo had to be extended. I think the sights were calibrated to take into account the bayonet or something like that.
You can shoot the M44 with the bayo either extended or folded and it doesn't change the balance. The ballistics of the barrel, however, are designed such that if you shoot with the bayo folded, you'll pull way off to the right.
