i have owned a m38 as well as a m44 there both a blast to shoot and extremely cheap and easy to mantain. the m38 i had was alot more accurate. just for shits and giggles i hunted and killed two pronghorn in wyoming at 200 + yards with the m38.
It's only $70 go for it, especially if you like to collect. If you hold out, get a hex reciever. You can easily find non-corrosive ammo because even newer rifles use the same round.
The 38/ 44 is a great choice also, I would get them both, the prices go up every day it seems like so get them while you can.
I have one of these guns and marvel at the men who used it. It is a great gun to shoot but do be aware of your surroundings. It shoots a powerful round and has a pretty good kick.
Great guns! Like was stated earlier you cannot go wrong for $70. I paid $60 each for 10 of them and got like 2500 rounds thrown in. But this was several years ago. I wouldn't hesitate to pay $70 with todays prices.
