my favorite is the 762x39. Was using the psak 47 rifle with folding stock and iron sights, due to optics fogging early in the morning in muggy weather. This year i went to psak 47 pistol with sig romeo 5. i use mine for hog dogging, so i like something small and light weight getting in/out truck and walking through the woods in the summer. Ammo is cheap, but very effective. You can also buy a case of ammo to stockpile for a couple hundred dollars.
