My friend Rhett Neumayer has been experimenting with an unorthodox but very interesting way to use handguns that don't have reciprocating slides. He fits a red dot optic on a relatively tall mount, then presses the back of the pistol into his cheek while gripping it over the top of the frame with his support hand. There are only a few pistols that can be used this way, like the KelTec CP33 and the Steyr SPP, but it allows remarkably fast, accurate shooting with a very compact presentation (basically the same as shooting a traditional handgun form retention). It's a really interesting idea, and Rhett has shown it to be very effective.
