I just came from a shop that had hi point handguns for next to nothing. is this brand reliable? I was told the barrel is fixed so it shoots straighter than alot of 1911's & others that have "loose" barrels. also was told they have a lifetime warranty, not just for defects either. I was thinking about getting 1 in every caliber but don't want anything that's gonna jam every other round or is fussy with what brand ammo it shoots.
