Fwiw, am a really thrifty/frugal broke near hermit
Depression's improved to the point I'm not concerned with it being a risk to myself and am currently nogunz except for varmint air guns
Considering dropping like two grand on a nice rifle 
and equipment and training with it alongside my gym routine
Debating getting either a KUSA KR-101X or a Keltec RFB and an optic and chest rig/plates and pouches, spare mags, etc for either
The KR-101X is a 5.56 AKM/74 clone that takes AR mags and looks pretty good from what I've seen, the RFB is a .308 bullpup DMR (I'm kinda a tankie and a big Halo dork, so both have their appeals)
Live in a state with a 10 round mag restriction, so that's leaning me towards the RFB.
Thoughts?
Dunno if there's a loophole for larger mags or a SBR "pistol" 
that might be a better option
Am I being a dumbass?
Should I get a pistol or a .22LR plinker first? Should I not drop a used car price on a rifle I might never have to actually use aside from playing at the range and running drills as a hobby?
@Tervell@hexbear.net pls lend me your wisdom and recs
Yes, it's a very poor idea. Makarovs are horrible guns. Get a glock, and if you don't want a glock get a cz, and if you don't want a cz get anything but some goofball museum piece.
See if any ranges in your area let you rent pistols to use on their range.
Also, i would recommend, if you're going to do tacticool, balance your cqc stuff with infantry stuff like shooting at range, bounding, travelling over rough terrain, outdoors stuff. Cqc in a real pitched fight is mostly terrifying bullshit where everyone dies. It's less "pie the corner" and more "blow a hole in the floor/wall/ceiling and drop grenades where you think the bad guys are until everyone is dead". Tacticool cqc is for us army soldiers terrorizing unarmed civvies and larping cops kicking doors down for petty weed charges. Learning how to shoot at range and coordinate with a fire team will see you a lot further.
It's important to decide: do you want a weapon or a toy? If you want a weapon get the most common, reliable thing you can. Ar15 for a rifle, and then a glock or another very common pistol for a side arm. A weapon needs to be easy to service and repair, it needs to eat the most common ammo around, and being able to share parts, ammo, and mags with your buddies isn't bad.
Thank you, very helpful
