Wow this is a tough one. I may have to cheat and list a few.
Pistols: Jericho 941R*. P226 Combat/TB. Five-seveN. A Nice 1911. Actually. None of these are hard to get, just varing levels of cost.
Rifle: TAR-21 Tavor. Galil ARM 5.56. Israeli Re-Arsenaled Mauser 98
Shotgun: Benelli M3 Super 90 Convertible
Subgun: UZI. P90. B&T MP9
LMG/GPMG/HMG: Negev. FN MAG. MG3. M2 QCB
Other: Merkava Mk.IV מ
Whats funny is how close I have come to some of these in terms of at least touching them.
Everything but the Mauser, Benelli, P90, MP9, and MG3 has been in my hands at some point.
Or in my arms for the case of the M2.
Or under my feet/around me for the Mk.IV.
As for The Jericho. I already have one, but it was bought used and the prior owner ceramic finished it. He did an ok job, but nothing great.
