A Glock17 Gen 4, A Glock 38 and a Glock 39 go to the range and hands down the Glock 38 shot the best for me. The Glock 17 gen4 had some soft recoil but I couldn't get it to group anywhere as tight as the Glock 38. The G39 even gave me better groups than the Gen 4 17. This was the first time I shot the Gen 4 17. The empty cases just fell out of the gun, the ejection was not forceful at all. Not to create waves but it might be a little over-sprung. I had one failure to feed and I was using Winchester White Box. All of my other 17's eat the winchester stuff up with out a bobble.
