Question: Will this fit my smith&wesson m&p 40 compact.
Document: I bought this for a Smith and Wesson M & P 22LR pistol which has a weaver rail. The problem with these sights are that you cannot tighten the fit, they are just a slide over. Impossible to stay on zero without a clamp. I use it to amuse the dogs at this point.
you get what you pay for. Not staright. Mounts loose.i tried this out on my Smith & Wesson M&P; 1911 bb/pellet gun
rails need to be move back some dosenot fix well on sub compact m&p;,on and off switch needs to be improved
I had recently bought a Smith & Wesson M&P;  22 caliber pistol.When I put this on, it wiggled. A small piece of paper, we actually use a little bit of a sticky note, fix the problem.I used a bore laser to sight this.
I got this for a Smith & Wesson M&P .45. I attached the sight like it is supposed to be, but when I did I noticed alot of play in it. I put a piece of double sided tape on it in an effort to hold it in place. Then I sighted it in, had it dead on. After turning the sight off, then back on again, it was totally out of sight.
Loose Fit but compact. . For this price it's an OK laser. Battery life a bit short. Zeroed as it should.
Thought this may work as a cheap fun alternative for my .40 does not work.. too bad. As a laser though it is ok.
Very good product. I like the switch much better than another I have with a "squeeze pad". I have it mounted on my Bersa Thunder 9 Ultra Compact and it is right-on with a boresighter.
Great product. Fits on my fianc&eacute;s M&P S&W BB gun AND my .40 semi auto's weaver rails! very bright and easy to attach.
I purchased mine at Walmart since it is available there anyway. But for some of you who can't, well, here's a review you can read here at Amazon.com before placing a purchase.I have an Umarex H&K; USP 6mm BB CO2 airsoft pistol. It's quite a good pistol and accurate within 30 to 40 feet (specially with a fresh cartridge of CO2; accuracy lowers as the CO2 depletes, of course).
Answer: yes
