I'll throw in my 2 cents worth....
I've been an LEO for over 37 years. Started out with a .357 magnum revolver, department eventually went to 9mm semi-autos. After 19 years left that department and went to another one which issued 9mm Glock model 17 semi-autos. I fell in love with Glocks, I was always a die hard S&W fan but the Glock is the only handgun I will purchase or carry now. We upgraded to Glock Model 22 semi-autos in .40 cal about 15 years ago. I hate the .40 caliber. It's really snappy to shoot so it's not enjoyable. I have a Glock model 19 9mm for off duty use but recently I wanted to upgrade to a .45 caliber Glock. I wanted something that if God forbid I had to use it, would be more effective than the 9mm which some departments have found to be wanting and I didn't want a .40. I took a look, a hard look, at the Model 30, Model 30SF and Model 36. Then I discovered the .45GAP (not GAP as in the store that sold Monica the blue dress, GAP as in Glock Auto Pistol). Several years ago Glock worked with Speer and developed the .45GAP round. Ballistically the GAP is identical to the .45ACP - I know....this is heresy to .45ACP/1911 lovers, sorry... The length of the loaded round is about the same as a .40 cal. This allows the use of the medium size (Models 17, 22, 19, 23, 26, 27) Glock frames with a .45 caliber round. The .45ACP Glocks are much wider than the models listed above and can be a little tougher to conceal. There are GAP haters out there who will chime in that the .45GAP is the answer to a question that nobody asked, Glock wanted a round named after him, yadda-yadda. Sig named a round after them, Colt has several rounds named after them, Smith & Wesson has several rounds named after them so that's a BS argument. The purpose of the .45GAP was to put a .45 caliber size cartridge in a 9mm/.40cal size frame - that's it.
The New York State Police, Pennsylvania State Police, South Carolina Highway Patrol, Georgia State Patrol and Florida Highway Patrol all issue the Glock 37/.45GAP to their officers. Florida did some very extensive research and testing when they picked the GAP over the ACP.
My model 38 .45GAP shoots much softer than the Glock .40 pistols. It's more of a push back in the hand rather than a snappy muzzle climb. The GAP's recoil is a little bit more than the 9mm, but not by much.
The downside? Yes there are downsides. Magazine capacity is less, they are single stack not double stack so you're not going to see 15 round magazines unless you go aftermarket. Ammo may be tough to find in your local gun store, but it's all over the place on the internet usually within 50 cents a box of .45ACP. I reload my own practice ammo so it's not an issue for me. For reloaders, the GAP uses small pistol primers (cheaper than large pistol primers), use .45ACP reloading dies and the same bullets that are used to reload .45ACP ammo. The cases are not cut down ACP cases, they are thicker at the base than the ACP to handle the higher pressures of the GAP round. I bought a thousand once fired cases for $60 off the internet so I've got enough to keep me busy for a little while.
If you are in one of the states where your state police are carrying the GAP you'll probably have better luck finding ammo in your local stores.
It may not be the answer to your question, but it's another option.
