I see your 99M has a high comb (Monte Carlo?) pistol grip stock the same as my earlier 99M had. However, while yours has a tang safety and standard weight fore end, mine had the safety on the bottom and a fat fore end. Also, mine was chambered for the standard short action .30 caliber cartridge of its day, .300 Savage.

I've always viewed 99s as specialized big game rifles. I hope you get some venison with yours. You'll like it even more if you do.
