## Questions & Answers

**Q: will it fit a S&W shield 9mm preformance center?**
A: I bought mine for a Glock 17. It fits perfectly. Tried it on two other pistols thinking I might buy another for my truck gun. Length wise it fit On a Taurus G3 but the activation switches aligned lower and not all the way to the trigger guard unlike the Glock. To long for a compact like a G2c. Great light!!! Hope this helps.

**Q: Does this fit the Glock 43x?**
A: No

**Q: I put this light on my smith and wesson 2.0 m&p 9mm 4.25”, handgun and it fits and works perfectly. however i cannot find a good itwb holster.any rec?**
A: werkz holsters......great company and great holsters. They have al kinds of light options.  I own two of them and they are great, pricey, but great!

**Q: Does it fit a Glock 19 gen 5???**
A: It absolutely will.
