The G23 and G27 are practically the same gun with the major difference being the grip length and barrel length and number of rounds in the magazine, and the G27 can use the G22 and G23 magazines. Some think the G27 felt recoil is greater, but I believe it is the lack of grip surface that gives that impression. The .40 S&W is a snappy round and both guns are lightweight at 31 and 27 ounces loaded. If the recoil seems to much consider the G19 or G26 or buy an aftermarket 9mm barrel for the G23/27. Having shot all of the above I don't perceive much difference in any of them especially if you shoot 9mm+P. They all have recoil but it's not anything most people can't manage. Hope this helps.
