I dunno, I mostly think I have too much stuff -- after awhile it gets in the way and starts owning you rather than the right way around.
I tried IPSC, but I'm both not as good as most around here and their egos bothered me a bit (even though they deserve it some, they are really good).
I'm a long gun guy in competition -- precision is my thing. With all those engineering years of making things better via feedback, I just needed to get into something feed-forward for awhile and succeeded beyond even my hopes. I am the current all time record holder at the local gun club (160 years) for shooting a "possible", in other words, all X's, at 100, 200, 300 meters off a rest with a gun I built. X's in hunter benchrest (that game) are about 1/4" diameter. 90 X's in a row! I find it amazing that a human can point a stick that well -- even if the stick is essentially a perfect laser, which that was, and with good bags and all. 25 mph gusts makes that a little more tricky, but you don't go explaining Zen to that crowd, which is how I handle wind in that mode.
I was a wet rag after that, but a funny -- the older guys there (all nice) were giving me all these tips, like I wasn't holding the gun right, I should take off the sling swivel to make it ride the bags better and all that kind of thing. They couldn't see the black holes in the center of the tiny black X rings with their optics. When the targets came back, well then, things changed -- they were still watching me close, but for a different reason. I keep some monkey trap mesh on the barrel, actually to keep wasps from building a nest in it. But they asked about that, so I mumbled something about barrel vibration damping and they all move in close -- then I tell them the real reason.
But I messed up, I didn't get it. That's an old boys club, you're not supposed to come on and beat the snot out of them, that's not what it's all about, its a social thing, mainly. So I laid low for a couple years and now they don't remember me so well -- but I don't take that gun there anymore, they'd all pick up and leave if I did. I now take "sleeper" guns and play the social game smarter. For example, take an AR to a bench-rest match and no one thinks you are a threat...heh.
I am still learning handguns, and my fave is an old .38 S&W mod 14 with a red dot on it. I am lucky there, my lab assistant (the guy in the middle of the pic on my homepage, Dave) is an instructor (retired cop), we teach together, me playing the part of the bad guy as I look right for that. He really kicks my butt on handguns and I'm still learning from him. But i can still usually get to him faster from 7 feet away than he can get his gun out of the holster, which is good for the students to see (and fun for us).
A cool exploit of his. We teach for concealed carry license stuff and most people we get only know guns from movies, a real bad place to start. So I set up this evil test. 8 helium balloons tied to a 2x4 in a line straight away from you, bobbing in the wind. One is purple, the rest white -- all same height. The purple one is the bad guy, the rest are hostages. Shoot just that one.
You have 5 seconds from a holstered gun.
Well, no fresh student can do that (neither can I most days), and they get a real reality check quick this way, which we think is a good idea. Then Dave goes up to the line, gun in holster. He just looks for about 3 seconds, pulls the gun and shoots in one deft motion, and only gets the bad guy. No one was unimpressed, believe me, that's hard. What I do for those demos is a lot easier, and I've practiced specifically that move -- I take my time on the first shot, and preload the force on my grip to get back down out of recoil fast, timing the lock time so it goes off just as the sights re-enter the bull -- muscle memory. It's just like playing drums (something that was my day job for awhile). You don't move when you want to hear the sound, it's all anticipation and pre-timing -- and confidence pulls the trigger on the way into the bullseye, not anxiety pulling it on the way out -- that's pretty much the secret. And it's easier all on one target than bouncing around them and running around like in IPSC. It doesn't hurt that I reload (ammo is almost free to me) and I have two ranges on my land to practice on.
BTW, I do that with a CZ 97-b, even though I have a super-duper 1911 race gun. Sad to say, the CZ just does that better. Looks like crap, I've not 'smithed on it at all (built the other one from the ground up from all aftermarket parts, the best) but hey, it just does the job better. It's too heavy to really carry, though. I carry a Ti Taurus ultralight .38 with a crimson trace laser in the grips, and that laser is a weapon on its own. "Do not look into laser with remaining eye". Which is the point, to make them run away, I never want to actually shoot anyone.
Our other anti theft (or just anti jerk) tactic here is to introduce the real pr**ks to one another and then sit back and let them self eliminate, which they usually will do with no further encouragement. You get two for the price of one that way.
