So I am looking to get into a self defense system. I already know Brazilian jujitsu. I train that as my sport art. I have a couple of kickers to add to this. So here they are:
Bearing in mind that physical engagement is only a very small part of what is "self defence", let's take a look at this.
1) I'm big. I'm about 6'1, but heavy. I'm looking for something that I can use my size and strength.
Irrelevant.
Look, stonewall, you've been around long enough to have seen this type of question from many, many others… so you know how this goes. Frankly, there isn't any art that is "better" or "worse"… it all comes down to how you make any particular art work for you and your physical situation. I'd also caution against looking to something that would rely on capitalising on such attributes… no-one attacks someone they think has an advantage over them, so such aspects are largely going to be nullified by the attacker, either by numbers, weapons, experience, drugs/alcohol, or simply by being bigger and stronger.
2) I carry a firearm 90% of the time in public (licensed and prospective law enforcement anyway...once I can get my girlfriend settled on her career path it will be my turn). I would like to have something that lets me get that into action.
You want the option of employing a firearm? Get to the range, and practice deploying/accessing it constantly.In terms of a system that will incorporate it… you're going to have to look at modern combatives systems… such as Krav Maga. Some Bujinkan schools incorporate the ideas, at varying levels of competence, but Krav would be the more likely go-to.
As far as getting your girlfriend on her career path first… hmm… honestly, if you were one of my students, there'd be some rather pointed questions… but I'll leave it here as saying that I'd advise you take a real look at why you're giving your priorities in that order… are you using her lack of career as an excuse not to look to yours?
3) I don't have a lot of time and I believe in fighting dirty. I don't do fist fights. I don't fight for pride. I'm not a "tough guy." I want something that really emphasizes quick and dirty and hard strikes.
Yeah… look, again, largely irrelevant. Going into learning a system with a pre-determined idea of what you like, then you'll leave yourself closed off to learning how the system itself teaches what (it feels) works.
4) I'm scared poopieless of knives. So something that teaches me to handle those would be nice.
Okay… many systems will do that… but have quite different approaches.
But, as always, looking for something that suits a customised ideal of your pre-conceptions of what you think works, or is important, is never going to be a fruitful search… and, in the end, it's more important to find a school you can get to, with an instructor you can respect and listen to, that you can dedicate time and effort to. Having a system that's perfectly matched to your ideals, but on the other side of the country (or world), or the instructor is someone you can't learn from (or doesn't know what they're doing), then it's pointless just looking at that system. So the first question is always: What's around that you can visit? followed by: Have you visited them?
I don't have a lot of time free either. But right now I'm just "shopping" for ideas.
Then let me get a little blunt.
You're wanting essentially a custom-designed system, but don't have the time to dedicate to it, or even look for it? Honestly, I don't see a lot of success in this area for you unless something there changes.
