To each their own
My threads pretty far back up, so I'll remind all that I own a light/laser combo that I have used like twice a while back.
In an effort to keep everyone's mind open I'll offer the following.
Without question:
Lasers are fun.
They can point out a lot of what you are doing in training. Watch it during dry fire to improve. Watch during live fire recoil to learn. GREAT visual feedback I think.
New shooters get great feedback from the gun this way.
Improve most shooters in range type conditions. i.e. flatish well defined targets. Not sure if bullseye types who shoot tiny groups at 25 or 50 yds. I'm not skilled that way, so I definitely remeber my 7 yard group being pretty awesome.
Oh yea, and hollywood loves them.
Probably true:
Those with poor eyesight are given a great help. I don't have issues (yet, knock on wood). I don't know how they stack up against fiberoptic/nightsights combo's. I'm sure I just don't get it, but a tiny red dot vs lit dots on my sites seem similar?
Open ended questions for me:
With Defense in mind, shots are close, and COM rules. I think the question is two dimensional at least. Will they allow a faster COM shot, Will they allow a more predictable COM shot at speed. Oh yea, and the COM needs to be a three dimensional target with a shirt. If I was doing this, I'd head to the woods and tack shirts to trees.... seriously.
Now, answer this question along these scenarios (I think typical defensive shooting). On the move, from a draw, from a nightstand (or drawer or whatever). From around a corner or in the open. Thro in a hostage shot too. Shoot in daylight, dusk. Ideally street lights and car lights too. Shoot in pitch dark using a flashlight/or the combo light.
Percieved downsides:
I'd be concerned that it's a different style than most of us have practiced. I'm talking about keeping the gun a touch lower. So you'll need to repractice or split your practice. Likely not a big deal, it's pretty intuitive.
Most guns don't have lasers, so this isn't a transferable skill. i.e. stuck using anothers gun.
My biggest percieved drawback:
I believe in KISS. Iron sights are pretty reliable and just are. Quality lasers aren't going to break easily or shift POA. My M6 uses CR123 batt's so I don't worry about them dying when not used (don't know about others). But, it just feels like one more that could go wrong.
Also, they just haven't caught on with police (where handgun is primary choice most times). If it was a clear winner, I'd guess we'd see more of it.
Bottom line for me:
In a defensive shooting, I doubt I'd be doing anything other than point shooting. I never see the sights on close targets in action shooting matches. I don't miss either
So for me, it's more trouble to answer my own questions than I see it improving my ability to defend myself.
I'd also be the first to admit that I haven't shot mine much. I think the choice would be different for newer shooters, and possibly for the most experienced ones as well.
Certainly, everyone can choose for himself. Some would have to overcome cost of ownership (mines already here). I doubt anyone here is "close minded", just have come to a different decision. Likely for a variety of reasons.
Lest anyone thinks I'm a naysayer, note that I haven't sold mine
Hmmm, come to think of it, I WOULD have more peace of mind re: my wife having one.
I'm worse than the politicians these days flip flopping around.
