While I no longer employ them I have used both the VM-2 and W-6 and if I were to choose again I would opt for the VM-2 because of its reinforced mouth. I’ll agree that holstering the pistol after the fight may indeed be ones last concern but IMO a reinforced mouth has other benefits often not thought of.

IMO a reinforced mouth-band has a more important function than just aiding the user in putting the gun away. I consider it to be an important feature not only because it makes holstering the gun easier while standing (especially if you’ve only got one hand available) but it makes holstering the gun possible while sitting in a car or chair or while lying on the ground. However, I think the most over looked aspect is how a holster that stays open once the gun is withdrawn will help a shooter in the event that they have to run the pistol one handed (such as clearing malfunctions or reloading the pistol) with either ones strong side or support side hand. Both of those operations are made easier when one has a stable platform to reciprocate the gun on and place the gun in when performing these vital skills. Try inserting a pistol into a collapsed holster using only your support side hand during an empty load or while performing a malfunction clearance and one will quickly realize the importance of a holster that won’t collapse.

Quoted: ...If my left arm is disabled, I reload in this manner: Hopefully I have some cover.  Drop to one knee - place right knee on the ground.  Weapon, at slide lock or a tac reload, gets tucked behind the knee of my right leg - wedged between my thigh and calf.  I remove the mag with my right hand, then reach to my left side and grab a fresh mag, insert the mag, remove pistol from behind my knee, operate the slide release, and party on. If my right arm is disabled, I perform the same drill, but place my left knee on the ground, and use my left hand for the operations.

The biggest problem I see with that method is that it makes you immobile. If I’ve already been hit I’ll hope to keep moving in the event that moving may decrease the chance of me taking another round. Dropping to a knee won’t let one accomplish this.

I can't visualize a scenario where I'd insert a malf pistol into a holster in an attempt to clear the malf. If I have a malf when one arm is disabled, I'm again down on one knee, most likely seeking cover.  The heel of my boot works great for hooking the front sight and working the slide.  BTDT. If I couldn't fix the malf, then the weapon ain't going back in the holster - guess I'd try to beat the mofo to death first - of course resulting in my demise.  But I have no use for a holster during any malf operations. At least in my world, the pistol isn't gonna visit the holster until the threat is gone.

Again, I most likely won’t be dropping to the ground in a fight, it makes you immobile. So stay standing and envision this similar scenario...

For one reason or another if your strong side or support side arm becomes disabled during the fight and you still have to reload your gun or clear a malfunction you can do so with the following method. By not taking a knee you can remain a moving target and hopefully be harder to hit while you’re seeking out good solid cover. At the same time you can reload your gun by ejecting the empty mag, placing the gun in the holster (conveniently open due to its reinforced mouth), retrieving a fresh magazine and inserting it into the pistol, and after removing the pistol from the holster reciprocate it on your holster or belt to chamber a round. You’re now back in the fight.

Similarly, the same method can be used to clear any malfunction... tap the magazine on your thigh or hip to insure it is seated, reciprocate the pistol on ones belt or holster, attempt to fire. If a double feed needs clearing the same applies... tap the magazine on your thigh or hip to insure it is properly seated, reciprocate the pistol on ones belt or holster, and attempt to fire. If the gun doesn’t fire catch the forward lip of the magazine on your belt or holster and strip it out of the gun, reciprocate the pistol on ones belt or holster a few times, insert the pistol into ones holster (again conveniently open due to its reinforced mouth), retrieve a fresh magazine and insert it into the pistol, and after removing the pistol from the holster reciprocate it on your holster or belt to chamber a round. Once again you're back in the fight.  

There are lots of ways clear malfunctions or reload ones gun with only ones strong side or support side arm but I have found that the ones list above allow the user to do so with either arm while still remaining mobile.

Quoted: If I have cover, and my weapon malfs, I'm staying put (probably) until I fix the prob.   Good luck moving if you're hit.  Being shot and possessing adequate mobility are not synonyms.

I’m not so lockstep in my method that it would preclude me from using common sense, the action of the fight will determine allot. If I were already behind cover I obviously would not move until I had to. A shot in the arm will not likely immobilize someone… you can still move and fight if you have the will. A wise man once told me if you know you’re hit you can win. But, conjecture being what it is, you may not have the will. I know of one gunfight where an officer took a round in the arm from a .32ACP and subsequently decided it was his time and he had lost the fight. After that he did, as he was shot with his own gun after giving up.  

So I guess what you're saying is that you're pounding it out with a guy and you don't have any cover, then you have a malf or slidelock, so you will move to cover while attempting to clear the or reloading malf.  OK...I'd like to you stand at your range, and intentionally create a malf.  Now, imagine a mofo is trying to shoot you, and your left arm is disabled.  Now run as fast as you can to some type of cover while trying to fix the malf and using your holster in some way.  Now, do it again with your left arm disabled, but this time, shoot your weapon to slide lock, and run as fast as you can to cover while trying to holster your weapon, retrieve a new mag, and insert the new mag.   Maybe using your holster after you get to cover might work, but otherwise you're gonna die, my friend.

Again, the circumstances and parameters of the fight will dictate allot. I can think of quite a few examples wherein both of our methods would fail and both would succeed. I was simply pointing out my reasoning behind wanting a holster with a reinforced mouth not trying to convince you my method was the ultimate for every event under the sun.

I could see the potential for reholstering when using a 6004, and reloading when running to cover.  But I gotta wonder why people shoot to slide lock when they have no cover. And my point is this.  You need cover to survive.  I wouldn't duke it out with a guy while just standing out in the open.  My first rounds out are designed first to stop the threat, and second gain me the time I need to get to cover.  My first rounds are fired while moving to cover.  Period.  No cover, no life.

I would never be so presumptuous to suggesting one method is perfect for all scenarios or that every fight will occur in an identical fashion. The fight will be different for everyone and the response will come as such. I was simply pointing out a method for clearing malfunctions/reloading the gun that, unlike yours, lets one stay mobile choosing to use that mobility will be dependant on an array of circumstances neither of us has the crystal ball to predict.  My fault if my point got lost in my words.
