Well, I see this as potentially both a training and an equipment issue. Not an uncommon combination ...
Some folks have often appeared willing to train to compensate for an equipment issue, and some folks often have appeared willing to attempt to substitute an equipment answer for a training issue.
The first time I saw one of the subject 'carbon fiber' retention holsters my first reaction (silent) was
flimsy piece of cutsie tactical frippery (frippery >noun (pl. fripperies) 1 showy or unnecessary ornament. 2 a tawdry or frivolous thing. -ORIGIN Old French freperie 'second-hand clothes', from frepe 'rag'.) No knee-jerk prejudice against tactical gewgaws on my part, huh?
(gewgaw >noun a showy thing, especially one that is useless or worthless. -ORIGIN of unknown origin.)
Relax, just kidding ...
I didn't tell the owner that, of course. He's not 'new' to the field in some respects. Besides, other folk's personal equipment preferences aren't necessarily always my business. His choice ... and his responsibility if the consequences don’t match his expectations.
Joking aside ... (and notwithstanding my personal thoughts and concerns regarding increased multitasking of my trigger finger) ... one of my initial concerns upon cursory examination was the retention release itself. It appeared a bit exposed in some respects, and I wondered about its resistence to interference from foreign objects, as well as its durability. I was curious to see how it functioned in frequent usage, especially since our range has a lot of loose sand. I’ll be watching the fellow with the new holster to see how things fare if his holster is directly exposed, in some manner or other, to the sandy environment. You know how sand can be ...
I see a lot of beat up holsters. More duty holsters than plainclothes holsters, granted, but I've encountered my fair share of daily activities over the years that offered some opportunity for my various plainclothes holsters to be exposed to abuse. It happens.
I personally prefer to use a holster which
does not require that I train my
trigger finger to do something other than remain off the trigger until I decide to shoot, and then properly manipulate the trigger when I decide to shoot. That's just my preference. The potential for hand (and finger) confusion can be enough of a concern in stressful situations, to my personal thinking, without throwing a new task at my trigger finger. Just my thoughts, though, and I'm nobody's expert.
FWIW, when I was new to the business, and carried a revolver, I never felt attracted to the older clamshell revolver holsters which required the trigger finger depress a button to release them, either. Before someone objects to my mention of the clamshells, because their activating method presented a direct exposure of the trigger finger to the trigger ... I realize that, and I only mention them because I didn’t like them for their requiring some action of my trigger finger other than remaining clear of the trigger guard, or functioning the trigger.
I think plastic/synthetic and leather holsters each have their individual weaknesses & strengths, with some occasional variability due to different designs. Nature of things. I've had the occasional quality leather holster stretch and lose proper retention over time, or be made slightly off proper tolerance ... and I've had a quality kydex holster experience total failure after being subjected to an impact that I didn't expect would break it apart.
Anyhow, as I was walking by one of the holster displays in a uniform store the other day I happened to notice the Blackhawk holster section. I remembered the holster the other fellow had bought, and it occurred to me that I might pick one up for some personal testing in a controlled environment. Might as well see what all the fuss was about ...
I bought the plain one, though, without the 'carbon fiber' appearance ... and without the retention lever. I just couldn't bring myself to get one with the lever. Sorry. I wanted to check out the basic holster construction and durability without bothering with the retention lever ... which I just don't feel drawn to, anyway, and which doesn’t fit my training. One thing at a time. Maybe later ...
As I was paying for it the store person happened to mention to me that they'd heard from some customers that the paddle was flimsy. I didn't bother to ask for details of what they'd heard, since I was buying it to check it out for myself, anyway. I was further told by the store employee, however, that if I had any problems with mine that I should probably call Blackhawk, because they'd heard from some customers that there was a new, heavier duty paddle available.
Everyone should have some reasonable familiarity (preferably meaning some type of training and experience) with their equipment, as well as confidence
in & with it ... both in it's design, construction, reliability & durabilty, as well as in their ability to properly use it under the anticipated circumstances & conditions for which its intended, right?
I'll try this holster in a controlled environment for a while ... and will carefully watch the owner of the other one equipped with the retention lever, as well.
It's just a piece of equipment, you know ... not a family member or a reflection on a personal character trait or attribute. No need for defensive reactions about someone else's comments and thoughts.
The careful development and consideration of objective information can be very useful.
