We’re hosting .methods for the third year in a row, June 7-8, 2025, for two days of Close Contact Gunfighter! 👊🏽

We’ve come to really dig Raul’s program. Simple concepts and lots of focused, practical application. If you’re carrying a pistol in any capacity, then this knowledge is super critical. No experience necessary.

⚕️We’re hosting in Granby, April 5-6, in 2025, for two days of Direct Action Response Training (DART)!⚕️

Kerry and his team are the best in the business at EDC medical gear and training. If you’re a blaster carrier in any capacity, this kind of knowledge is as necessary as the LTC/badge itself. 👊🏽

Course overview:

“When life expectancy is measured in seconds and help is minutes away, will you know what to do? In our uncertain lives, that is a question that we all need to be able to answer a resounding, “Yes!” to. Dark Angel Medical, LLC, is proud to offer training and instruction in the use of the D.A.R.K. The Direct Action Response Training** fills a niche between military self-aid/buddy care training and civilian EMS training and is geared towards those with little to no medical training or background. It provides the student with critical, need-to-know information, which can be utilized in a myriad of situations and stresses the ‘you don’t know what you don’t know’ principle as well as our own principle of “Simplicity Under Stress”. The course is 2 days in length with a total of 16 hours of classroom work to include slide presentations, videos, question and answer sessions and hands-on practical skills application. A manual and all training aids will be provided. ***There are no prerequisites for this class***”

This year, Joe & Joe at asked me if I was interested in coming onboard as a TeaMM Pro staff member. I thought about it for a total of seven seconds, just to be sure they hadn’t accidentally called the wrong dude. 🤣

This is hands down the best rifle I’ve ever shot. These things are built for duty use, shoot super smoothly, and can take a beating. They’re affordable, and the customer service team is the absolute best in the business. 👌🏽

As a carbine shooter, I’m still exploring how best to mount this thing to maximize its ability to perform the way it was built to: fast as f* #€, super accurately, and aggressive as all hell. I’ve got 10 years of not-so-great police and Marine Corps rifle training to shake and bad hips to do it with. I’m happy with the progress thus far, and It’s actually been quite fun. 😈

As a carbine teacher, I’m here to help folks focus on what matters most when they train, so they can improve their performance ON THEIR OWN… and avoid the outcome-based kind of practice at the range that will inevitably hold them back. I’ve learned a lot about that from dudes who happen to have been on the TeaMM Pro staff a lot longer than me. 👊🏽

If you’re an agency looking for the right carbine, ModMat is the way. If you’re non-LEO, have faith, we will reverse H. 4885 and when it happens, you’ve gotta give one of these things a try.

CASS5 will save you a few bucks, too! 🤟🏽

The 2024 Pistol Capstone is a wrap! 🙌🏽

We’re constantly developing this program, with one goal in mind: to show gun-carriers HOW to train and which concepts matter most.

This was our third Capstone, and it was by far the most effective. Planning is already underway for next year’s Pistol AND Carbine Capstone metrics and curriculums.

Really, really great group of shooters! They pushed us as much as we pushed them!

Now, get to work (dry)! 👊🏽

Pistol II is in the books. They beat the rain, too! 🙌🏽

These dudes crushed it, and they’re well on their way to becoming super accountable with their blasters. 🔫

Two LEOs, two software engineers, an electrical lineman, a plastics engineer, and a physicians assistant. Probably our best spread yet. 👊🏽

Time to get to work at home, with a dry gun! 👏🏽

We think about training in three distinct ways:

1. Training to MAINTAIN. This is about making sure you can perform “to standard,” whatever your agency or personal shooting standards may be. Most, if not all of this kind of training can be done dry.

2. Training to DISCOVER. This is about exploring the most efficient way to manage accuracy AT SPEED: the speed at which you can press the trigger and the speed at which you can move. Sometimes, you have to temporarily sacrifice accuracy to see what your mind and body are capable of. Then, it’s about doing what you can to get your eyes and hands to “catch up” to the faster pace of things. This can happen dry and live.

3. Training to CONFIRM. This is about verifying the exploratory work you’ve done. This is not to be confused with MAINTENANCE. Sometimes, this kind of training gets you thinking… maybe it’s time to raise the standard. 🤔 This happens live.

You have to know which one you’re doing, and HOW you’re going to do it. 👊🏽

Police are shockingly far behind the curve. Shooting is shooting, and how a competitive shooter does it is exactly how an officer should on the worst day of his life. How a competitive shooter trains is exactly how an officer should be training.

I began prioritizing my vision, grip, a little bit of trigger control, and mobility (in that order) eighteen months ago. Since then, it’s felt like I’ve gotten 300% faster and more accurate - and 1,000% more consistent - at shooting. Considering I went to my first academy in 2017 and “have gone to the range” at least monthly, sometimes weekly since then, that’s not good. It’s sad, actually. I’ve waisted a lot of time (and money).

This is an official call to all departments in Massachusetts and across the Northeast to re-prioritize the fundamentals, push reputable fi****ms training on your patrolmen like you do the detail list, and if you’re a trainer, focus HARD on showing your people HOW to train, so they can get really good (and really accountable) on their own. Incentives work. They always have.

This is an unpopular stance, but stop buying guns.

Instead, buy ammo, some basic targetry, a shot timer, a range membership, a medical kit, and a class from a reputable teacher. Then, get to work.

What’s happening in Massachusetts with H. 4885 is a gross violation of 2A rights. We know that, and it’s why we believe whole-heartedly the laws will not stand.

Similarly, however, it’s not good for anybody if we have a state full of lawfully-armed Americans who don’t train (the RIGHT way).

Your right to own and carry fi****ms is critical… but so is your responsibility to be accountable, fast, and accurate with those fi****ms.

Calm down, and focus on what matters. 🇺🇸

Concealed Carry Pistol is in the books!

Tourniquets, performance from AIWB, and a much lengthier-than-anticipated law and liability discussion (which was fantastic).

Very confident these dudes know where to go from here with their training and how to think about carrying a pistol in public.

SUPER confident won’t ever have a problem accessing his TQ. Also, Chris took the concept of CONCEALMENT to the right level; he doesn’t want ANYBODY (even IG) to know he has a gun. 🤣

Now, get to the dry work! 🤟🏽

There is no secret to becoming really good (and really accountable). There are no advanced techniques, fancy guns, or coveted methodologies that get the gun up and rounds moving faster to where you want them to go.

Getting really good (and really accountable) takes hard work; the understanding and application of a few key principles, some exploration, and a s**t ton of hard work. That’s it.

If you’re going to classes to learn, but you’re not exploring (and testing) the application of all that learning on a regular basis, you’re wasting your time.

The “teachers” who aren’t talking about this are more-than-likely feeding you bad information. They’re also more-than-likely facilitating a “depend on me” kind of learning environment.

Our goal is to teach our way out of business… to get you to understand exactly what you have to do, on your own, to get really good at shooting.

We may lose support over this, and we’re okay with that. 🫡
