My KRISS 9mm Gen2 SDP with brace showed up on Friday and I took it for a spin today. I used a Trijicon RMR on a low Bobro mount, 100 rounds of 124 grain FAE, and 50 rounds of 147 grain Federal HST (my 9mm oh shit load). All rounds fired unsuppressed; would you believe that I do not have a 1/2X28 fixed barrel adaptor yet. Here is how it went:
1) Function: All 150 rounds cycled reliably. Unfortunately, none of my factory 33 round mags will reliably lock the bolt open on the last round. Moreover, it often fails to lock back if I retract the charging handle on an empty mag. It locks back on these 33 rounders about half the time. Having said that, all of the 17 round mags locked back without a problem. It also cycled with my 33 rounders; it was just the lock back that was an issue. At first I thought that I was hitting the slide release button with my support hand (very easy to do when placing that hand on the lower receiver), but I confirmed multiple times that this was not the case. Although this is a little frustrating, I'm encouraged by the fact that I accidentally dropped the damn gun in a puddle of mud - it cycled the last 5 rounds without a hitch (I had the foresight to finish the mag before cleaning it).
Anyway, it started to rain again, and my FDE rifle was covered in mud. Thus, I've not had time to play with the mags after rinsing it off as my old lady was mad as hell that I was late getting home.
2) Accuracy - No issues. It seems to be a tacdriver. However, the rail is away over the bore on this bad boy. Thus, I almost maxed the drop on my RMR to get POI / POA at 15 yards (this is a CQB gun).
3) Recoil - no different than my MKEs or MPX. It is softer than my Scorpion which seems to have a bit of bite compared to my other 9mm guns. Some people describe less muzzle rise attributed to the unique mechanism. I'm not sure that I noticed a difference.
4) Balance / Ergos. It is not exactly light. Not that I'd advocate putting the brace to your shoulder, but the tube is the perfect height for a cheek weld if you were to raise the brace to your cheek without touching your shoulder, of course. The gun feels good with your support hand on the lower in front of the trigger guard. However, be sure to keep your hand off the slide release. Also, the placement of the mag release is not intuitive and takes some practice as mentioned in a previous post.
Overall, I like it. I may really like it once 1) I get this bolt lock back issue resolved with 33 round mags and 2) when I get my Hera Arms folding adaptor. More to follow....

I like my rifles like my women - short, light, fast, brown, and suppressed.
