I've not used any of JP's rifles, but they are generally regarded around this forum as super top notch rifles.  I believe they were designed around 3 gunners needs and quality was definitely one of them.  I am using one of their silent capture buffer assemblies in one of my pistols and it really is a top notch product.  

If you do a search I believe a couple guys around here have JP's for 2 gun and also wrote up some extensive reviews on one of JP's full sizers(caliber wise), but I am not quite sure.

I've had one for just over 3 weeks now.  I did a quick photo and write-up on the first range session that I posted on their FB page.  Since that session, it has been to the range 4 more times.  Dead-nuts reliable.  Not one failure at this point.  Probably close to 1000 rounds of various types/makes of ammo.  Still getting used to the lack of a last round bolt hold open but, as I said in that initial review, I'll take that all day long over what went before.

Thanks, I am aware that jp rifles are very high end. I do a lot of 3 gun shooting myself (private course).  I am itching for a 9mm carbine and I really liked the ddles but I am aware of that mess (maybe if those are ever available again it may be an option ).  I also think that LWD has their package running good.  But to drop 1100 on an LWD or spend 400 more to get a jp makes me think the extra 400 is worth it.  Although im still about a year away from buying, I like to do my homework.

do you have a link to the review you posted?

The lower is very similiar to the Lone Wolf lower I just got in to build another 40 S&W on........the mag catch is almost identical except for the texturing on the surface you push on.....

OK, here's what I wrote:

Not sure why there's not a lot of chatter here or elsewhere about your 9mm carbine so I thought I would chime in on my new acquisition. I've been shooting 9mm AR-platform carbines, both factory and personal builds, for a number of years now. I mostly use them for training on steel CQB ranges where rifle-calibers aren't appropriate. The carbines I've used in the past have always been hit-or-miss in functional reliability. Failures to feed or eject were the primary bugaboos. Magazines that one gun liked were spit upon by another. Buffer/spring combinations weren't consistent between different guns even of the same make. All have been ammo-sensitive and I usually had to pick one brand/type of ammo in order to reliably get through a class. And, of course, each different carbine liked a different ammo diet. When I first saw mention of the JP Enterprises version I figured that if anybody could get it right, you could. A reasonable, not-too-long wait after ordering, and I took possession of mine. After mounting a RDS, I went to the range with a trunk-load of ammo to see what I could see. After sighting in the RDS with some Black Hills match ammo, I started loading magazines with factory ammo that was a no-go in every carbine platform I had tried. While this ammo functions 100% in my pistols, it would fail 99% of the time in my carbines, mostly failures to eject. This ammo functioned 100% out of the JP. I ran at least 300 rounds through it with not one functional failure. I ran another few hundred rounds of otherwise marginally successful brands and, again, had 100% reliability out of the JP. To say I'm pleased is the mother of understatements. Fit and finish on the gun are second-to-none. The only concern I had was the lack of the last round bolt hold-open. That will take a little getting used to but I think the trade-off between 100% functional reliability vs an occasional dry-fire on an empty chamber will be worth it. Thanks to the JP crew for a great product.

When you charge a JP upper does the channel cover slide straight back towards your face?

If you're asking me, I have no idea what that means.  Regardless, it operates just like any other AR-style carbine.

It was a question for anybody that has one of the JP side charging uppers.  From the side it looks like there is a cover over the slot the charging handle moves in.  I was wondering if it comes close to the operator's face when charging the rifle while maintaining cheekweld.
