I'm using the Remington 180gr HPs in my 40cal Glocks. Never had any problems with them in compact or sub-compact. I personally think the 40S&W is an inherently more accurate round compared to other calibers....at least that's my experience. Not a wide range of loads to select from in the 40cal since the overall cartridge is near the peak for it's performance level. 165-180gr is mainly what you'll find unless it's something exotic. I tend to have my favorites for my 9mm and 45ACP pistol loads, but the 40cals pretty much run very well with whatever I have tried. I did pick up a box of Winchester PDX1 for 40S&W last year. Have not tried them yet, but it's a small box 20 or 25 rounds I believe. I just bought it because they had it.
As far as cycle problems.....we never know. Things go south when you least expect them to do so, and problems don't always show up at the range during practice. Keep those malfunction and clearing exercises in mind.
You can trust a machine (or any mechanical thing) just as much as you can trust a human not to let you down in the heat of the moment. Stands to reason.....man made machines and mechanical things.
