If you keep an eye in the EE, the Razor's do come up for sale now and again. Personally, I'd put up a bit more $$ and go with the Razor and not worry about being able to handle the bashing that the slide will give it. I have a couple of buddies that went through a Venom and a Viper twice and then switched to the razor and have not had any issues since. Trijicon RMR is a bit more than the Razor, but they are bomb proof. I'd rather pay a few bucks more up front and not worry about equipment failure, hence the old adage buy once, cry once.
