I have a low-recoil Knoxx BreachersGrip™ on my "Kentucky Carry" Mossberg 500 Cruiser J.I.C. with an 18.5" barrel. Anyone that can legally own a shotgun can affordably equip a suitable short-barreled $200-$300 Mossberg or Remington with a $75 Knoxx BreachersGrip™ and proper sights, and then learn to repeatedly fire his pistol-gripped shotgun painlessly and accurately to about ten yards. This proposal runs counter to current popular belief. But seeing is believing.
Some people might like a better way to shoot a pistol grip only - PGO shotgun or want one for a heavy artillery truck or car gun, or to keep in a motel room for added protection when away from home. With practice a stocked shotgun can effectively be fired below the line-of-sight at chest level with the stock tucked under the arm to reduce recoil. Eleven of the great gunfighting instructors of our time have endorsed below-line-of-sight, off-shoulder, chest-level shotgun shooting methods as viable for extreme CQB under seven yards, which is the range of over 90% of handgun confrontations, to wit, Mr. Paul Castle, the late Mr. Jim Cirillo, Mr. Massad Ayoob, the late Mr. Bill Groce, Mr. Chuck Taylor, the late Marine Lieutenant Colonel Jeff Cooper, Dr. Ignatius Piazza, Mr. Gabriel Suarez, Mr. Lance Biddle, Mr. Michael T. Rayburn, and Mr. Randy Smith (plus 58 other C.A.R. system instructors in 22 states in the U.S.A.). By searching about 75 posts on several forums, I noted that about 60%-70% of PGO shotgun owners prefer chest-level, below line-of-sight shooting. I specifically recommend that stocked shotguns are best for HD. But it is also important to practice shooting a shotgun without using the stock, in case one must shoot in a tight space or around a wall, furniture, or a vehicle without overly exposing himself. This long-established LE tactic is the fastest possible shotgun technique for very close quarters. It is an optimum ready position for cornering and "slicing the pie." The shotgun is safer from grabs because it is held close to the body, projecting less muzzle. And the muzzle is always kept oriented in line with the eyes. To learn to effectively shoot a PGO shotgun to about ten yards, one can practice the LE tactic of shooting a stocked shotgun at chest level with the stock tucked under the arm.
Two photographs of Mr. Michael T. Rayburn looking over the shotgun barrel have been removed at his request. They can be found on p. 80 and p. 82 of his excellent book, Combat Shotgun: The Ultimate CQB Weapon.
I researched the internet for ways that people shoot their PGO shotguns, and about 60%-70% of them fire from chest level. The first time that I tried this method at the "rifle" range, I blasted 112 shells from about 20'-25' to my target, and I noticed that eight or ten officers came over from their adjacent range and were standing with their arms crossed watching to see who was making all the noise. I liked that, because I knew that they were seeing a PGO shotgun being shot effectively and rapidly, without using the sights. We saw tiny pieces of cardboard fly at every shot, all 20'-25' to the silhouette, and I was always deliberately firing about six shots in five seconds or less. I had absolutely NO discomfort or wrist pain, thanks to the Knoxx BreachersGrip. (The Federal Tactical LE132 reduced recoil 00 buckshot works for me, way better than economy Royal RIO full power 00 buckshot.)
To change to chest-level shooting from my previous eye-level shooting, I removed my EOTech 551 from my PGO Mossberg Cruiser and put it back on my Kel-Tec PLR-16 5.56mm pistol. I did not really like the EOTech and my thumb coming so close to my teeth when I fired my springed Knoxx BreachersGrip-equipped Cruiser at eye level. It takes time to both line up sights on a PGO shotgun at eye-level and to not knock your teeth out from shooting too fast. I did not like how that caution for the sake of my teeth really slowed my firing down. That is why I researched and learned that 60%-70% of PGO shotgun users fire from chest level, and so the EOTech had to come off. But the great increase to speed of firing convinced me that learning to fire by lower-than-eye-level sighting is worth the effort.
One can observe how this slight girl holds the gun at chest level, keeps her right elbow straight back, and lets her arms swing naturally together to easily control recoil. The young lady should actually use a boxer's stance, turn the receiver 30 degrees toward her chest, initially hold her left forearm (and the PGO shotgun) less far forward, keep the barrel horizontal to the ground at all times, and look down the barrel with her head about 6" above the barrel. Just give her two more minutes of education and the camcorder could have recorded her making little cardboard clouds at every shot from 20'-25'.
I have every intention of always practicing this way from now on because I want my subconscious mind to remain totally familiar with the little visual subtleties of my correctly aligned barrel at chest level making little clouds of cardboard without using the sights. Practice, practice, practice!!!
