I'm not a fan of 45-degree offsets. I've tried them in a few different configurations and that angle just doesn't work for me. But this one o'clock angle allows me just the right amount of offset (to give space for the carbine to fold), but still enough stock still in my shoulder pocket. And I have it enough height so my ear pro isn't impinged.
 
Pfft, now everybody else is gonna be putting Military grade plasma array lasers on their Keltecs and soon your's won't be so special. Until then though: enjoy! :)
 
A new update on my ammo choice:

I chrono-ed some normal self defense 40 ammo (180gr HST and 175gr Critical Duty) and was getting the exact same velocity out of 16 inches that I was getting from my Glock 22. That sucks. So I decided to figure out a load that would maximize the use of the long barrel.

I found the magic!!

I bought a few hundred Hornady XTP 155gr bullets. I found a few hundred nickel-plated brass cases for that high-zoot look of over-the-counter self defense ammo (Win, Speer, Federal, Hornady headstamps). I chose Hodgdon Longshot powder because it is so slow-burning. I used Winchester SPP's for consistency. OAL of 1.125"

I set up a ladder from 8.0 grains, up in 0.2 increments, to 9.2 grains. The published max is 9.3 grains for this combination. Today I went out and shot through the ladder. The most consistent load ended up being 8.8 grains. Boo-yah!

Would you believe the average velocity (with a spread of only 46fps and SD of only 20) was 1560 fps!!!!

That's 838 ft-lbs of kinetic energy!!! Zing! Out of 40S&W!!

Be interesting to explore similar optimization for .45ACP PCC's...
 
This load rivals 10mm! Could you imagine a carbine-maximized 10mm?:eek: That would be a laser from God's hand!
Yeah, an optimized 10mm or .460 Rowland/.45 Super/.450 SMC oughta be a fight-stopper... the rub is, for something like Da Choppa you'd need a commercial loader to supply enough of it.

Man, imagine if Eliot Ness had had us to keep his TSMG's fed... the Capone gang woulda been toast.
 
I really love what I've put together...but I think I may have let it get a bit out of hand. After all the receipts have been added up, this $500 carbine (KelTec Sub2000 Gen2 for Glock 22 in 40S&W) has become a build that cost over 2 G's. :eek::confused:o_O:(:) And I wouldn't have it any other way. It is exactly what I want, and that is the point of personalizing guns, right?

My use? This is for self defense when I need the ability to fold it up and stow it away. For example, during the eclipse, I chose to drive into the totality zone and nobody knew if it would become crazy town with traffic (it didn't). I just wanted to be ready. With a Glock 22 on my hip and this thing folded up behind the car seat, I felt pretty good.

Above, you'll see a big part of the cost is the Octane 45 screwed to the muzzle.

Above you can see the Magpul AFG2, a Crimson Trace Rail Master GREEN laser since my wife prefers lasers over sights or red dots since she is cross-eye dominant. Easy to turn on from the angled grip. You can also see the Trijicon RMR07 angled to the side so I can fold the rifle. It includes a Magpul rail piece, a Weaver 1 o'clock offset picatinny mount, a Yankee Hill 1/2" riser to give it that last bit of height for my preference, and a Trijicon low picatinny mount for the RDS.

My desired VTAC Blue Force QD padded sling requires a mounting point fore and aft. I had to drill 3 holes in the stock to install this Magpul QD point and used an M-Lok QD mount for the front.

One mag option I have is a 22rd Glock mag with a +3 from Taylor Freelance for 25 rounds. This photo of the Sub2000 folded up is this carbine's claim to fame. If I chose to remove the suppressor, it could be even shorter, but it takes a long time (if under attack) to screw on a can. I prefer to leave it on.

From Tacticool I got this neoprene cover. The moment I decided to buy this was when I shot this PCC while 25 degrees out. Ahhh! Cold steel against naked cheek was no fun. But it requires you to use the longest stock setting to not have to cut the cover. Fine with me! Even though I'm only 5'10", the longest stock setting works for me. Thus, this carbine might feel too small for a tall guy unless you find some sort of shoulder pad that would work for you. Below, that's an MCarbo charging handle. Really works for me, better than the 1-finger stock unit.

You can't quite see everything above, but I changed out the trigger (steel feels better for me), the springs (much smoother and lighter trigger), trigger guard (I would NOT do this again, in fact I may switch it back out), and some upgraded screws, all from MCarbo. They came out with a cool extended mag release button after I did this stuff. If I buy it, I may remove the trigger guard while installing the mag button. The stock trigger guard allows a one-handed take-down with your thumb, but this "upgraded" part is too smooth and requires 2 hands to actuate.

To round out this self-defense lovable monstrosity, I've got a Streamlight flashlight, mounted to a Magpul M-Lok picatinny rail piece with a FAB defense 1" offset mount. This mount is quick release without a tool so I can take off the light to use it off the rifle, if necessary. This set up keeps the folded carbine as slim as possible with still having a light on one side and a red dot hanging off the other side.

I've done the math, which ends up around $2200, I think. Wow, this build added up. I may end up switching out the RMR for a Vortex, which could drop it below $2000, but I love it as it is. And one word about 40 over 9: The main detraction of 40 is that the recoil, greater than 9, makes follow-up shots a bit more difficult. But that is in a handgun. In a carbine, especially with the can attached, this caliber gets me a significant amount of power over a 9, but without much extra recoil. If this was a range toy or a competition rig (for USPSA PCC), I think 9mm would be better. But for self defense in a shoulder-fired carbine, I'm really liking 40!!

Okay, y'all, it's time....

:s0024:FLAME!



Boy be cra-cra.... :s0125: o_O

Have a gen 1 sub2000 in 9mm, wish if were a gen 2, that rail makes a difference.

MechTech makes carbine uppers for pistol lowers. I have one in 10mm. You can get some great velocities out of a 10mm with a 16in barrel and slow burning pistol powder.

Seeing .40 cal holes on a target compared to .223 is also funny.
 
Since this suppressor needs a fixed-barrel spacer (instead of the Nielsen spring), I've discovered I need to change a few things to switch it over to any of my pistols. So if it is set up for the PCC, I really won't be swapping it around between different firearms.
