Pistol Caliber Rifles
Having a rifle that chambers the same ammo as the one used in your sidearm is very practical...
Hi Point Carbines can be purchased in 9mm, 40 cal and 45 cal...
The Kel-Tec Sub2000 is also a great carbine to accompany your Glock 17/19.
To complement your .38/.357 cal handgun I recommend a Marlin or Henry lever action rifle in .357 cal
The best thing about pistol caliber rifles is most indoor ranges allow the guns to be fired in their enclosed ranges.
