It's about sights and gun control. I wouldn't be so bold to make such a claim, but Rob Leatham got me pointed in this direction - he probably knows a bit about shooting. However, even before that, I was already seeing in my shooting that accurate rapid fire and the proverbial 'trigger control' dogma are conflicting concepts.
So accuracy in rapid fire is not about trigger control - it's about sights and maximized gun control. The prevailing dogma about trigger control is that it's the most important part of shooting. You can have your sights perfectly aligned and miss the shot because you jerked the trigger. I'm sure we've all heard that as if it were the ultimate shooting maxim. But, you can also miss the shot with perfect trigger control if you anticipate the shot and flinch - that's lack of gun control. A perfect trigger pull won't help a bit with that.
I shot this yesterday at Shooter's Depot indoor range. The 3 inch dot is at 5 yards. The gun is a box stock gen 4 G17, yep, you read that right - box stock! I know it's hard to believe I haven't made any mods to it , but I haven't. BTW, the dot connector Glock now puts in gen 4s is so good, I doubt I'll replace any dot connectors with after markets - they're that good! At least for me.
The camera is zoomed in 5X (all that camera will do) so you can see the hits better. BTW, you may notice my shots are slightly to the left of center. I believe that is NOT sight misalignment but a correction I've made to my grip causing the left bias.
And, I guarantee, I am not squeeeeezing the trigger, I am actually slapping and jerking it. So how do I get by with that? Simple - gun control. If I control my gun sufficiently, then it doesn't matter how I pull the trigger. As you watch the vid, consider that in about 0.42 seconds, I'm recovering from recoil, reacquiring my sight picture, and pulling the trigger. If it takes 0.21 seconds to recover from recoil and acquire a sight picture, how much time does that leave for trigger control? Only 0.21 seconds - that's a trigger jerk, not a trigger squeeeeeze. BTW, I got that from Rob Leatham. Rob says something on the order of, "...I know traditionalists are going to hate hearing this, but you can't go this fast [referring to his shooting, not mine] without jerking the trigger." Well, I can't shoot as fast as Rob, but I can apply his principles - here goes...
For slower fire, all that emphasis on trigger control may be true - I'm still working on that.
I don't want to give the impression that trigger control can be ignored, or that one can just go out and yank on the trigger any ol way and get good accuracy - you'll be disappointed if you think that.
But, what I do want to emphasize is that shooting at speed, is about gun control, not trigger control - at least not trigger control in the traditional sense. If you can control your gun so well that pulling the trigger doesn't disturb the gun, then it really doesn't matter how you pull the trigger does it?
