    One thing to point out is lights that extend past the muzzle tend to collect more GSR than ones that end behind the muzzle. They’ll both get some on it and you’ll need to clean the lens periodically.

    The advantage of having the light go out past the muzzle is that if you press the gun into someone it won't go out of battery. Like for instance in a struggle and you are pushing the gun into the attacker it can still fire.

    Pencil eraser works great for clearing that up and then toss chapstick or other similar oil on the lense. It'll make it so further crud just wipes off

    If you are planning on running an Olight, make sure to use high quality batteries, ie Surefire or Streamlight, I've heard issues about Olights blowing up due to faulty batteries, this include Olight branded batteries. If you are going to run a surefire, make sure to losen the mounting screws BEFORE you mount it on, and then tighten it while it is on the rails, when I first mounted mine on I had to hammer it out due to the screws being too tight

    I've been using the Battery Junction CR123s

    Supposedly has protection for short circuits. Been ok so far.

    That’s what chainsaw bayonets are for. :lol2:

    I’ve been carrying a streamlight TLR1 on my duty weapon for 7 years. I’ve seen the switches break on them, I JBwelded the problem areas on mine so the issue doesn’t happen to me. I’d recommend looking at the sure fire brand.

    I'd rather have 3 TLRs than 1 Surefire but that's just me.

    You going to throw that on your pistol? ok?

    I'm a fan & owner of Rein's and Owl's on SBR/Pistol AR's...

    yeah, i was thinking their micro is smaller than it is...
    So I'll clairify...
    The Owl & Rein are the two best lights for pistols & rifles, but for pistols they're more suited for the ar/ak platform pistols with 7-1/2" + barrels than the plastic fantastic's like the Glocks...

    I always have a light on at home 24x7 and have battery backup emergency lighting and do not currently own a light for a pistol in the glock size...
    I may get one for one of my 1911's though. But a revolver is my go-to for home defense...
    no magazine springs to go south from being loaded too long, never has a fail to feed.

    The Streamlight's are better suited to the glock size pistols and would be hard to beat for that footprint imho.

    Never in the history of semi magazines has this been proven true.
    Compression and expansion(use) of those springs weakens them.

    Why are Owl and Rein lights the best?

    One vote for the streamlight here. I have the 8A flex.

    I have a surefire as well, my newest, and I regret it a bit. The switch is very stiff and difficult to operate. The streamlight is VERY easy to control. The surefire will probably end up on a rifle, or something that can mount a pressure pad.

    One thing I like about the surefire, is that it extends a bit past the muzzle on my fnx45tac. It should prevent the slide going out of battery, in a close contact type situation. It is brighter, but that can be a liability as well, a lot of reflection back at me indoors.

    actually the loaded spring fed magazine fatigue issue is a well known, documented fact...
    Which is a major reason why those that are aware of it don't leave their mags fully loaded, they'll usually load 1 or 2 less than full capacity to extend the fully loaded, and sitting fatigue life and or cycle their loaded mags at an interval.

    There are many that claim to have never experienced the issue and that you can leave them loaded indefintely, I disagree and have had way too many personal experiences with multiple firearms to say it's not a legit issue. So for home defense I go with a revolver to not take a chance, one less permutation for me to consider. For EDC I carry fully loaded mags, which I reload and cycle every day. I have 8 mags in rotation.

    My Glock 36 (.45acp) litterally had rounds fall out of the mag after sitting loaded for a month at a time... brand new glock factory mags, multiple times... sitting compressed fatigue, not load, shoot, repeat fatigue.

    IF you've ever seen sagging leaf & coil springs on car's and trucks, they got that way from the vehicle weight on them 24x7 and or towing and substained, prolonged compression is what shortens the life of all springs more than compress & release.

    This is a well-known, age old problem, I first learned about it 30+ years ago in the USMC in bootcamp as applicable to then m16's and 1911's.

    I guess spec ops guys should use revolvers.

    that's not what i'm saying.

    In a nut shell if you want to have a zero percent chance of a bad magazine spring or a fail to feed which are two problems unique to semi auto's...

    A revolver is a good choice in a home defense scenairo for at least those two reasons.

    Peace.

    I mean, if you do the fix I did, they are fine. My supervisor had one on his patrol rifle and the switch cracked and snapped off while he was shooting. One of my shift partners had his switch crack and fail as well, he sent it in to have it replaced. I believe the fix was free. I haven't heard of this issue on the surefire products. I am aware they cost more but the original post referred to money not being an object. Personally I would like to pick up an XC-1.

    Revolvers have a lot of points of failure on them. They aren't the model of reliability relative to something like a glock that you're suggesting they are. Something cool about them is that if a primer is bad, your next trigger press automatically clears the malfunction for you with no tap rack bang... assuming it's not a popped primer that jams up the mechanism.
