But I did it on the cheap

I own a G20SF 10mm and so with a conversion barrel, I can also shoot 40S&W in it. Kind of like 38 Special/357 Mag.

I ordered a Lone Wolf standard length for this - stainless barrel with standard rifling.

I figured that 40 is so prevailent now and often in stock when other calibers aren't - especially 10mm - which is also expensive.

It's also less expensive to handload and the brass is cheaper if I have to buy it. But I can get loaded FMJ Winchester for $32/box of 100, which is very inexpensive - 165 grains at 1060 fps. Should shoot to the sights close enough. That's why I chose the 165 vs the 180's.
