So most of you have probably read many different opinions abut the Gen 4 Glocks, but I'm going to go ahead and beat the dead horse anyway and throw mine oht there too. I picked up a G19 Gen 4 a little over a year ago. I had always gravitated toward 9mm's because I had never before shot a 40S&W that I found to be very pleasant to shoot, and I personally have issues concealing a 45, especially when it's a Glock. Even tye Sig P226 in 40S&W was unpleasant to me. I decided I wanted something that hit a little harder though, so I rented a G23 Gen 3 because that's all that was available to me for rent at the range (as in they didn't have a Gen 4 for rent). I found that to actually be somewhat enjoyable, to my surprise, and I noticed no difference in my ability to shoot or control it compared to my G19, which I shot back to back with the G23. I went ahead and ordered a G23 Gen 4, which I just received the other day. I out a few rounds thru it, and WOW am I impressed! It feels pretty much like I'm shooting a 9mm! The felt recoil is substantially better than any other .40 I've shot in my opinion! I would high recommend this pistol, even to beginner shooters! It's very easy to control, it actually feels pleasant to shoot, and it's very accurate. I love this thing! Nice job Glock!!
