I was just thinking about this - here's what I'm looking at, roughly in order of "want / expense ratio", for my short-term and medium-term lists (out to 6 years):
1. (definitely) GOOD 9mm pistol suppressor (to use with 9mm pistol, 9mm carbine, .338 Spectre carbine subsonic, .22lr pistol, and .22lr rifles); also will need a threaded barrel for the CZ 75s.
2. (probably) Taurus 738 TCP, .380 acp (for "jogging carry", belly band)
3. (maybe) Kel-Tec PMR-30, .22 mag (for fun)
4. (probably) Boberg XR9, 9x19 (for everyday SmartCarry)
5. (probably) Kel-Tec RFB, .308 (for fun and younameit)
6. (maybe) MSAR MCS-08, 9x19 (for fun)
7. (probably) Air Force Condor, .22 cal PCP airgun (for backyard critters)
8. (maybe) Ruger Redhawk 5.5", .45 Colt (for hunting backup, fun, younameit)
9. (probably) Stevens Goldwing 612 SxS 26", 20 ga (upland birdies)
10. (maybe) Browning BL-22
11. (probably) My custom long-range heavy bench turnbolt in either 7mm WSM, .280 Rem AI, 6.5mm-'06, or 6.5-.284 Norma (for sniping, what else?
)
12. (definitely) My custom SBR suppressable .338 spectre turnbolt (for fun)
13. (definitely) My custom SBR suppressable .22lr turnbolt (for fun)
14. (maybe) Bull-pupped Saiga 12, 12 ga (for fun & home defense)
In truth, I'd be happy to come up with any 2 or 3 by year's end, or just one of the most expensive ones (#s 11-14), since I'm now broke.
Believe it or not, I've got all of the REST of the bases covered.
