Was shooting today doing some final chrono testing (confirmation really) of a .40 load that is going to be produced. It is one I have been working on for literally over a year. I passed the 2K round mark in testing and am very happy with the results.
As an aside, while I was out, I put some of the hot .40 rounds through a Gen 5 G20.
They ran through the gun perfectly, just as easily as they ran through the Gen 3 G22.

In my experience .40 S&W has not generally been a particularly accurate cartridge, (excluding custom race guns).
I’m glad to see someone else say this. I’ve had a few .40’s, down to one right now, and have never been really inspired by the accuracy I could get out of them. The one I have now is okay, but just okay.
I have put LOTS of typical issued .40 practice ball and duty ammo down range in duty type pistols and generally speaking, the .40 in my experience has never been a particularly accurate cartridge in most service autos. There are some exceptions to that but for typical service autos and work type ammo, that has been my observation and experience. Race guns/hand tuned or built guns are a different subject.
In this case, I spent quite a substantial amount of time developing a load that shot well in your typical 3rd generation and newer Glock .40 barrels (and other .40s). Developing a load that has the accuracy, as well as reliability, and is a high velocity load takes a good bit of T&E. I put a bunch of rounds downrange before I was satisfied.
One of the key things I was also looking for was potentially a carry gun for large animal defense, aka big bears, that was not on a large frame. I absolutely love my .45 Glock as well as the Glock 10mm. Both the 10mm and .45 are awesome guns for the outdoorsman. But in observing people shoot, I have noted that pretty much everyone handles a standard 9mm/40 size frame better.
They are more accurate and faster.
They simply perform better.
Most people don't shoot enough high performance 10mm or .45 to truly be proficient with it.
So, I worked on this +P .40 load that pushes a Poly-Coat 170 grain semi wadcutter at 1200 FPS out of a G22. That is a very fast load for a .40, and it is very accurate. So a guy can use his concealed carry gun as his trail/defense gun.
