If I had a list of guns I must buy, the shockwave and anything similar is way down that list, like at at the end of it, after almost everything else.
And I don’t own a shotgun with full stock and pistol grip. Never will. I’ve shot them.
I would agree to meet you at the range and shoot skeet, sporting clays, or even a combat course. Your pistol grip anything against me and my non PG shotgun and I will outshoot you.
I might not look as Hollywood Uber tacticool but my 20” 870 with extended mag and big head safety is as modified as I need and I shoot my stock beretta 390 even better.
OK.
First course of fire: Put your shotgun in a normal back pack and zip it up. On buzzer, draw it and fire one round at a target.
Second course of fire: Conceal your shotgun completely (So that it can not be seen from outside the car) under the seat of a 1992 Honda Civic. On the buzzer retrieve it and fire one shot at the target outside the passenger window while sitting in the driver seat.
Third Course of fire: While wearing a plate carrier with 7 full 30 round M4 Magazines, IFAC, 4 C.A.T's, 3 Sig P320 magazines, Sig P320 full size, and four full grenade pouches, and holding a loaded AR-15, secure your shotgun in a scabbard on your back. On the buzzer draw the shotgun and deliver a breeching round to a simulated door without allowing the AR to touch the ground.
Fourth course of fire: In a shoot house that simulates travel trailer, store your shotgun next to or under a full size mattress in an 8x10ft room. On the buzzer get out of bed, secure your shotgun, travel down a 24" wide hallway with a 90* right turn. At the turn deliver one round into a silhouette 36" away.
