Maybe the fact that so far I haven't been able to afford such fripperies isn't such a bad thing. I started with iron sights and don't have to worry about devolving to confusion at a critical time. Note that cataract surgery has taken my vision from Mr. Magoo to Top Gun, thus extending the useful time for irons.
Better to perish in the struggle for freedom than live to see defeat.
I have a couple of lasers on a few of my smaller handguns, J frame, Kimber Micro 9, M&P 9c and I like them, especially in low light but I do still shoot with iron sights more than the lasers on all of these guns during practicing.
I bought a used (pre-lock/MIM) S&W Model 640 that came with a set of Crimson Trace laser grips which the previous owner had installed. I left them on because it seems a reasonable alternative for a handgun for which it would not be easy to install tritium night sights (which is my preferred low-light solution). In all honesty, though, beyond zeroing the laser to my load I haven't shot it much. My wife liked it enough to request that I also put a set on her Model 60.
I bought a Ruger LCP with an integral laser only because it was on sale ($227). Prior to that I never gave lasers much thought. Since that purchase I have realized that they DO have a place in low light L.E. and personal defense applications.
