This seems like a great accessory. Though I am skeptical to start changing out internal parts of my gun. The price is not something that I'm willing to toss around, but I'm interested. Has anyone had any expirence with this item? https://www.lasermax.com/ProductDetails/tabid/127/ProductID/1/Default.aspx
Works great on my M&P9. Easy to swap out with the original guide rod and works as advertised. Can't adjust it though.
used one in a 4in 45 acp compact , and I used one in a 3in sub compact , liked them both , only one thing I noticed while using it to target shoot, it will smudge up using lead cast bullets, I always pulled it out if I was going to shoot a lot, one to save wear and tear on them , and easier to clean the gun afterwards
