Here at TRGRiQ, we are fans of pistol caliber carbines. While some may turn their noses up at them, we recognize their potential. Since the days of the “Old West,” Cowboys saw benefit from having both revolver and lever action chambered in the same caliber. There was an advantage to only having to carry one type of ammo. Today’s modern platforms are more advanced and faster handling. Combined with soft recoil for faster follow-up shots, low muzzle blast in tight spaces and less over-penetration when compared to most rifle cartridges – all make for great CQB work. While there are several variations that have come and gone over the years, most notably the HK MP5 and UMP, there’s one that we particularly like for its familiarity and customizability (it’s a word, look it up).
