KAPP 45 FRAME
I can not recommend this frame enough.  I love this frame.  It beats my friends benchmark times ten.  This frame has 3 different set screws to take out the side to side play.  When you get a new frame, you will have to get a new spring kit.  I have a madmann on mine, and I love it.  My trigger pull is butter.  There is no slop, and it is so smooth. To anyone who wants a new frame, I highly suggest you let a tech put it on because it may go out of time, and you may not know how to put it back together correctly.  The next nice thing about the KAPP frame is the houge grips.  These are extremely comfortable and stickey.  And just feel good when you are walking with it.  One of the nicest things about a new grip is the way it looks.  These things make your gun look very cool.  I suggest the KAPP frame to anyone.  This is one of the best investments I have put on my gun.
