The recoil of 40 is overly exaggerated and is internet regurgitation at this point. Unless you are a 90 lb Jockey with cancer, you can handle 40 with little difficulty.
I have both in Gen 4. I love them both, I shoot both equally well, If recoil is an issue for you then train more. My wife carries and shoots the.40 with no issues.
I carried a G23 for most of my LE career. In retirement, I have owned a couple of Gen 4 G27 pistols. Currently I own a Gen 5 G27 and, in my opinion, the shooting experience with the Gen 5 G27 is much better than any G27 I have owned or shot previously. Interestingly, according to Glock, the Gen 5 G27 is virtually identical in weight to a Gen 4 G23. The only downside I have found to owning a Gen 5 in 40 is that some holster makers do not offer a holster for Gen 5 Glocks in 40.
Friday morning Hammer video, instant thumbs up even if it's a Glock video. Being a member of the Croatian brotherhood of the XD any word if you'll do a XD mod 3 video?
These two are too small for full comfortable grip, I wear LG/ExLg glove and I want full three finger grip comfort. My preference is my G17L, G17C, G40 and G25. Yes the G25 is the same size as the G19 but it's for training with ladies and first time shooter friends. A 'full size' .380acp. Glad to see respect for the basic pedestrian Glock. 👍
I rented a g23 gen 5 and the beefier slide makes this gun shoot real nice for a 40 and the recoil would be a non issue for just about anyone who shoots 9mm
