It is our considered opinion that you should not use this product. Last SF company before retirement bought 90 or 100 of them circa 2003 (an SF company has 84 officers & men if at full strength, plus operational floats) and we discovered the same thing everybody else has: the Serpa has three serious safety-of-use problems, either of which alone would be enough to recommend retiring and destroying the holster and using anything else. Even Mexican carry.
We understand why the Serpa holster was designed. Pistol retention is a serious problem for anyone that tangles hand to hand with hostile persons. The police are more likely than armed forces to throw down mano a mano, but any soldier or Marine in ground combat can wind up in that place, the good old unsought fist fight or grapple-for-the-gun game. Many police forces, and some military units, specify a retention holster for just that reason. But there are a number of ways to design a retention holster. There are three reasons that the Serpa is the wrong way:
Safety of Use Issue #3: Stuck Pistol Syndrome
The Serpa does provide positive retention — sometimes too positive, especially if grit, sand, gravel or mung in general gets into it. If it gets into the retention release mechanism, Jesus Christ Himself isn’t getting that thing open. That’s rather a problem, because if you’re like us, you don’t generally go to unholster a gun until the situation has already gone uncomfortably nonlinear. The only thing worse than pulling your gun too soon is pulling it too late. The only thing worse than pulling it too late is attempting to pull it, and then failing to pull it at all, after signalling that you were going to. This problem by itself should be enough to disqualify this holster family.
Safety of Use Issue #2: It’s Slow
No matter how much you drill, the trigger-finger release is going to be slower than some of your other options. Worse, it’s going to be less consistent, because from time to time you may address the holstered firearm a little differently, and it doesn’t take much change in alignment to miss the flipping catch. If you miss the catch, you have to grope around, all while the clock is ticking. There are holsters that don’t make you do all this, so this problem by itself, also, should also suffice to disqualify this holster family.
Safety of Use Issue #1: Increased ND Risk
This is the biggest Serpa problem that people talk about. By using your trigger finger to disconnect the gun, and then having that finger fall on your trigger you great we increase the odds you’ll touch off a round with the pistol aligned somewhere other than at the proper target.
This video (NSFW but understandable language) shows an experienced shooter having a very typical Serpa ND. In the slo-mo at about 0:57-59 you can see exactly how it happened.
In this case, there was a combination of negative transfer of training from the more conventional 5.11 holster that this shooter used with another pistol, and the Serpa putting his index finger too close to the projectile initiator, too early in the draw sequence. Tex says he doesn’t blame the holster, he blames himself; fair enough, you can’t have an ND without human input. But his tools made the ND easier, instead of raising obstacles to an ND.
As we’ve said, every one of these issues is serious enough to warrant discarding the Serpa holster (and any holster that works like it, with an index-finger release paddle). But the increased ND risk with the Serpa is, in our opinion, the most consequential of these issues and the one that, even if you dismiss the other two, needs to sink in before you have a mishap like Tex’s.
We’re not sure even he knows how lucky he is. Mere inches from the channel that .45 slug dug in his thigh is one of the superhighways of the circulatory system, the femoral artery. A bullet in that artery would have led to his incapacitation in minutes, and ultimately, death, unless the right first aid was available extremely rapidly. He seemed to us to be alone on the range. How often have you shot, alone? It’s a calculated risk.
Doing it with a Serpa makes the calculation all wrong.
It’s not just us
We aren’t the only ones who just say no to Serpa. For example, Paul Howe wrote in 2005:
Another problem … a recent student …. exerted excessive pressure from his trigger finger to the unlock button and when drawing the weapon, drug the finger along the holster and into the trigger guard, discharging the airsoft weapon prematurely into his leg during his draw sequence.
Trigger fingers are just that, for the trigger. I think it should remain straight and have one function, to index the trigger.
I have banned for almost two years now Serpa style (trigger finger paddle release) holsters from my classes – several other instructors and training facilities have done the same. …. I understand many shooters use Serpa holsters on a regular basis with no issues whatsoever. However an open enrollment class environment has its own set of challenges … and a trigger finger paddle release holster is asking for trouble.
At this point, pistol-training.com is going to follow the lead of other instructors such as Larry Vickers and ban the SERPA (and the various cheap knockoffs on the market) from classes beginning in 2012. I have been suggesting to students that they bring something else to classes up until now and will continue that for anyone who is already registered for a class in 2011.
And earlier that year, in reference to the Tex Grebner accident video posted above:
[T]he SERPA retention mechanism certainly lends itself to such accidents more than most other holsters. Instead of keeping your trigger finger well clear of the gun during the initial part of the drawstroke, the SERPA and its clones require you to press your trigger finger toward the trigger as you draw.
A lot more instructors say about the same thing. Travis Haley, Chris Costa, and a lot of guys you never heard of but that have seen these things cause one problem after another even on what should be a routine flat range. Rational Gun has a list of some of them, but Google will find you even more. (For example, RG has a link about the FLETC ban, but we don’t believe he mentioned the IDPA ban on the Serpa).
Yet this thing is still on the market, and people (and worse, agencies) are still buying them. Don’t Be That Guy™.
