My pair in 9mm...
I have a Hi-Point C9 9mm pistol (~$150 in California) accurate to 25 yards. Haven't shot it at any longer distance. This gun has always been very reliable for me with only one failure to feed in 300 rounds that was caused by a slightly out of spec round.
I also have a Hi-Point 9mm Carbine. (~$350 in California (OUCH!)) accurate to about 75 yards. After that the 9mm round becomes a bit of a flyer going high and left. The carbine has 10 round magazines that also can be used in the C9 pistol. The 8 round C9 pistol magazines are too short to fit in the carbine. This is a fun carbine and is great for close in distances! Also, 9mm ammo is relatively inexpensive.
For longer range I have a Remington 7615 pump action (like the 870 12 Ga.) that chambers both .223 Remington and 5.56 NATO rounds. Uses AR-15 magazines and doesn't require the
California Button since it is not a semi-automatic. This one cost $650 in California a couple of years ago. I have a cheap (Tasco) 3-9x40 scope and it is quite accurate at 100 yards. Haven't tried it at any longer range due to lack of longer ranges in my area but I think it should be good to about 300 yards or so.
Of course everyone needs a scattergun so I have a Remington 870 pump in 12 Gauge. The 870 and the 7615 operate the same way so are a compatible pair even though they don't share the same ammo.
My next longer range, more powerful gun that I am going to purchase, will be a Rugar Gunsite Scout in .308 (About $750 in California if you can find one, they are quite popular).
I also have a Bersa Thundar 380. Unfortunately, I cannot shoot the Bersa without it misfeeding every fourth round or so.
My Son-in-law can shoot the Bersa with no problems at all,
so I guess my hands are not designed for the Bersa!
And for the garage I have a pair of Crossman 357 .177 air guns (revolver style). Great for practice on non-range days.
Dang guns seem to multiply on their own!
