It is the shooter, not platform. One cannot miss fast enough to win-or STAY ALIVE.
Ask any instructor, ask anyone that has been in harms way, been in a gunfight--90 % is mental and all that emcompasses. 10 % is the rest, the least of which is platform, more important is gun fit (handgun, rifle,shotgun) and training/trigger time.
I grew up and stay with the antiquated, 'swing through method". Much like the "bird, belly , beak, bang" method in England. For me being able to match angle, speed -especially if changes occur- is best. Works for stationary targets--or I am the one doing the scootin' and shooting.
Of interest: pump guns actually have a unique characteristic, kind of an accident. Much like learning to drive a stick, then owning nothing but auto trannies...
At one time people learned to shoot, officers qual'd with revo's out to 50 YARDS. Since bean counters decided what guns to buy, training went south, higher mag capacities, and "spray and pray" was born.
The pump: many persons shooting doubles and the swing through actually had an advantage. After firing the first shot, the human eye/hand computer "re-evaluated" speed, angles ...and in shucking the shooter "bird belly beak, bang". Target down.
The new shooters didn't have this skill --always, like many today couldn't qual from 50 YARDS with bling bling blasters.
The shooters whom learned on single shots and pumps, transitioned very well. But again, trigger time allows them to shoot anything quite well.
Me, heck I don't care what you shoot.I'd probably grab my 29 y/o autoloader, but I'm sentimental... pumps-- Model 12's fit me, I'm biased, but these things shuck awful fast for a poor boy. 1300's fit, I have to buildup combs on 110's and 870's...but heck, I still can walk 1/2-2/3 way between sta8 and high house and break them. Unmounted gun-of course. Low 8 get 1/3--my best was 1/2 using an o/u.
I've won 3 Benelli's, a 11-87, some other stuff. IMO the 1100 is a better gun. Benelli's don't fit....and jiminey...I traded these in w/o taking out of boxs. Rather have a used 1911 I wanted. goes toward a pallet of shot I split with some others, cases of wads or kegs of powders. My priorities.
