Bought the M9, flawless.
If I may suggest, at least from my perspective, I would like to see some of the most common pistols in their basic configuration.
Pistols:
1911, CZ75, Makarov, Sig226
Some bolt action rifles and pump action shotguns would be nice too. And obviously M16 and AK47 and AK74 rifles. The HK416 is too new and too niche in my opinion, while a regular AK47 or 74 would fit into many more settings. “Civilian” guns would be more in demand I would guess on the indie market.
