HD, you'll like it a lot. M38's kick like a mule. M39 is pleasant, due to added weight. Best Mosin, IMHO.
Surf AIM and Wholesale for prices and conditions- don't settle for junk or pay too much at the gun show. The wood can be fantastic on these...
Bring a bore light and cleaning kit to the gun show- people don't tell you that.
Shipping's only $15... Be picky. Expect a so-so one for $150, excellent but maybe dinged VG shooter for $200, brand-freakin' new for $300-350. Bore is critical (duh- sorry). You can re-blue, not worth it to re-barrel.
Email me if questions- I just read the "Mosin-Nagant Collector's Guide" from Amazon- until I forget, I'm full of trivia.
