The only mods to my LCP has been the Crimson trace Laserguard, and the pearce mag extersion. As the LCP has marginal sights to begin with. I felt the addition of the CTLG would help in low light situations or when shooting from odd angles or from the hip, as in draw and shoot quickly. and I was right. I liked it so much I purchased one for my SR9c/SR40c the same LG works on either pistol.
