## Questions & Answers

**Q: Is this grip equivalent to a stock medium grip?**
A: yes, the grip is nearly equal to the stock medium grip and hardly noticeable.....i highly recommend it....

**Q: any lefties using this grip and and does a normal grip obstruct the laser?**
A: I don't believe that it makes a difference if you shoot left or right handed. The laser sits above where your fingers are and will not be obstructed. This crimson trace will replace the grip. The only reason I would suggest not to purchase it would be if you had the ambidextrous safety. I love my crimson trace, so much so I also put it on my conceal weapon.

**Q: Will it fit m&p full size 10mm**
A: Not sure. It fits my full size 9 M&P. You could reach out to CT directly and ask. Great product though,  I have 2

**Q: How is the laser activated?**
A: Once your laser grip is in place there are two button on the very rear of the grip.  The one lower on the grip is recessed and turns the laser on and off contrary to the first comment.  The non-recessed button at the top of the grip activates the laser when you have put the gun in your hand and gripped it properly for firing.  When you relax your grip the laser goes off but does not completely turn off. That is done when you have pushed the lower recessed button again, to save batteries.
