RANGE REPORT
I've had the rifle to the range twice now. Bottom line - this is a great little rifle.
I'm still waiting for mags to arrive, so I used my XD40 mags. I had several feeding problems, with rounds hitting the feed ramp but not going up. I had to hold the rifle under the mag. The mags were also very tight coming out of the well. I assume that factory mags will solve the feeding problem.
The trigger pull is long, with a lot of spongy creep until any tension. Once through the slack though, the break is nice.
The rifle is heavier than I thought it would be for a small rifle, and with steel Ruger rings and the red dot, it's even heavier (though it's still not 'heavy' at all), but it's balanced perfectly and is very pointable with super-quick target acquisition.
I'm looking at a tactical flashlight now, not because I need one (need? don't be silly), but because the

factor would be huge.
A fellow CGNer had his new Storm in .40 at the range too, so I had the chance to do a head-to-head comparison. The Storm is lighter but kicks a little more as a result. My second shot times were slower. The Storm has all those pretty rails, so accessories are plentiful and easy to mount. I found the length of pull on the Storm to be too short - but I'm 6'2" 200lbs. so it's probably right for most people, and I found it hard to shoot with full size muffs, they kept getting in the way. I like the option of ejection to either side, I'm a lefty, though this wasn't a problem with my PC4, which ejects with considerable power, so I don't get hot brass in the forehead.
The 2 rifles are very similar in performance, but overall I like the PC4 more. My friend likes his Storm more, so we're both very happy with our new guns.
