I'm not as convinced as Rexter, but no. Guns go through trends. I remember back in the late 80s/early 90s, when in the movies, all these guns had extended barrels or compensators. Guys at gun shows selling junky, two-piece screw-on compensators for ten bucks. Haven't seen one lately. Now these things still exist, but they aren't nearly as prevalent. I do think that a chunk of the market share for people who buy guns with rails are people who will buy them, and in their whole lifetime, never put anything on them. They will look at them in ten years and wonder why the heck they got that thing. Guns with rails won't fit in conventional holsters, and aren't particularly well-suited for carry when you can get grip-integrated or guide-rod contained lasers without using the rail. You can have a light in your pocket or next to your spare mags, and use it separately from the gun, and use it WITH the gun when you NEED to. People have been doing it for decades. This will always be easier than jamming a Glock with a light hanging under it into your waistband. You can add rails to existing guns, and darn near all accessories that you can put on a rail, you can get one that latches to the trigger guard, or clamp an aftermarket rail to a regular gun. I think that in ten years, there will be models of most guns AVAILABLE with a rail, but most guns for sale in the average store won't have them.
