Question: Will it fit a S&W M&P .40 Compact? What material is it made of? and What type of batteries does it take?
Document: I love this light! It fit my S&W M&P Sub compact .40 perfectly. I also purchased one for my M&P 9mm. Clips on very easy with a very tight and secure fit. Very BRIGHT light with no rattle or movement. For the money this light is well worth every penny. I would highly recommend it if your looking for a good price for a nice product.
I looked for a long time on Amazon for a pistol light that would be very bright, strobe, and not stick out from the end of my S&W Sigma (2005) 9mm. This is it! Measure the length of your attachment area and see what will fit (if that matters to you). Most lights are about 3&#34; or longer and look obtrusive and bulky in my opinion. Not this one!
works as advertised . i like that its short so it dosent stick out to much from my M&P 9mm .
It is quick and easy to install it at night and remove it the next morning once you practice a few times. The light protrudes about 1-2 cm from the front of the barrel once installed. Note that the larger HiLight model does not fit the PX4 Compact, which apparently has a &#34;sub-compact&#34; sized rail.
Though I might not recommend this for duty use, it is perfect for home defense use. The fit is snug, and does not wobble at all. It goes perfectly on my Springfield Armory XDM compact. Very bright light. Although the one way switch might detract from lefties, it is still very easy to function with both trigger finger, and opposing index finger from either side of the light. Also, the strobe function is a nice bonus.
The HiLight P5S is a very well made weapon light. It mounts very solidly on a Glock full size and compact with little to no movement. I fired 100 rds of 45 ACP with this little light on with no malfunctions or issues. the light is exceptionally bright but I wish the beam was a little more concentrated as it has quite a large concentrated beam, but it throws a lot of light and really lights up a room. The strobe function works great and passed the firing test as well.
Light shipped on time and works great, super bright. The only problem is the on/off button sticks out too far on the sides so if you want a holster you will prob need one custom made. Still a great light for the price.
I know I wasn't buying a top of the line pistol light, but this will fill the bill for me just fine. It sits on the rail of my Sig Sauer P229 and stays next to my bed. I'm taking it to the range in a couple of days to try it out with both .40 cal. and .357 sig. I'll update my review after I try it out at the range.
Looked at alot of lights and alot of reviews on this product. Everyone was helpful and right on, that's why I went with this purchase. So I'm here to keep the 5 stars coming. Took it to the range this weekend with my son. Had it on my compact Stoegar Cougar 45 , Baby Desert Eagle 45 , and Full size Tanfolio 9mmSlides on all guns very easy, stayed on , with the light on and then strobe.
Would I suggest this light to anyone? Yes!
Answer: yes
