I went out and picked up a HP C-9 for grins and put it through its paces. Note that mine was not handed to me by a MKS employee. This is an off-the-shelf unit that I'd picked up for $150 OTD. I also purchased 4 other factory mags with the pistol.
Today at the range . . .
Out of 10 loaded mags shot (five separate new magazines) only ONE magazine did not suffer a failure to feed or eject. Of the mags that did jam, more than a few had more than one FTE/FTF. Almost every one of the FTE/FTFs could not be resolved through tap-rack-bang. Because of the design of the slide/ejection port, stovepipes usually required disengaging the magazine while holding the slide in the rearward position, as there is no external slide release/lock.
The ammo used was WWB, UMC Yellow Box, Brown Bear, & Silver Bear - each brand of ammo was used at least twice in two different mags.
The same ammo was used with a 5946 to ensure that the ammo was good. The 5946 had zero malfunctions out of 10 different loaded magazines.
- Groupings at 7 yards were more like 10" shotgun patterns - although every shot landed on the B-27 silhouette (by contrast, groups of 1" to 2" with the 5946)
- Cycling time was slow.
- Ergonomics was ok - The extended magazine made it easier to shoot -vs- the 8 round mags
- For a 9mm, it had snappy recoil
- Trigger was gritty and rough, even for a single action. This is coming from someone who thinks the Sigma's trigger is ok.
From additional research, it would appear that the magazines, like the pistol itself, requires a break-in period. Having to run through 250 to 500 9mm rounds before deeming a pistol reliable would cost the purchaser an additional $50 to $130 + tax and/or shipping, depending on ammo used.
Based on this unscientific experiment, I think that someone who could not afford more than a couple of hundred for a firearm & ammo AND had performed some research on the Internet would be crazy to buy a Hi-Point C-9.
For the same amount they would spend on the gun and break-in ammo, they can easily purchase an used S&W Model 10, a FEG PA-63, a NEW Armscor .38spl, or even a used Taurus 82 .38spl and be able to rely on it in a crunch.
But hey, I would never say that unless one can afford a Sig 226 they should save and wait. All I'm saying is that there are alternatives out there. RELIABLE alternatives that don't require 500 rounds of break-in.
