Depends on which you like better and which is a better fit ergonomically. Glocks are good firearms but I was raised shooting 1911s and I have never been happy with the Glock grip angle. I did manage to force it to work for me when I won a GSSF Regional Match but it was awkward. I have owned several Glocks including 17, 19, 17L, 22...but never kept any of them. The only Glock I own now isn't a Glock at all but is a CCF RaceFrame that I built up to use with a Mech Tech carbine conversion.
In today's political climate I would hesitate to sell any hi-cap firearm, it may become irreplaceable in the near future. If you like your Glock keep it and save up for the Kimber.
