Took the new Kel-Tecs out today.
P15: 60 rounds thru the P15 and it was perfect in terms of reliability. It's a handful without the extended mag in it. The second mag fits flush with the bottom of the grip so there's not much to hang on to. There's a good bit of muzzle flip and the trigger is mushy with an almost non-existent feel for the reset. The concussion, for some reason, is really pronounced. Recoil impulse is pretty sharp but manageable. The sights are OK...fiber optic front with black-notch rear. Nothing hurt fingers or hands, nothing sharp, etc. The mag release is problematic. It doesn't protrude enough to get a good purchase on it without really shifting the gun in my hand in order to depress it far enough to release. Inserting mags is no problem. They go right in and lock into place easily. Definitely needs a taller mag release. There's nothing about it that's compelling enough to make me want to carry it over the other choices I have. But I can see where it would make a pretty decent choice for someone with a limited budget.
Sub2000: I set up a bench at 25 yards to zero the CT-1000 red dot. I fired one round just to see where it was. Dead center on windage but about 9" low. Without even figuring how far to turn the elevation dial I just rotated it a complete turn. Fired a 2nd shot...it was right on the right edge of the X-ring. Sweet! I'd rather be lucky than good. I fired three more rounds with two going thru the hole from the 2nd shot. The third was about 1/4" left. I gave it just a click or two of left windage and it was perfect. I fired 100 rounds thru it of all sorts of assorted ammo I had. There were 3 failures to eject...basically stovepipes... and all 3 were with Herter's aluminum cased ammo. I had about 20 rounds of that and it really felt underpowered for the blowback action of the Sub2K. Everything else, including about 30 rounds of Tula steel-cased stuff and a couple of different types of hollow points ran perfectly. This is a great shooting gun and I think it would make an excellent HD gun, especially with a can. The recoil is pretty substantial (relatively speaking for a 9mm PCC) and is probably due to the blowback action. The gun feels really solid...not flimsy in the slightest. The CT red dot is about as basic as they come but it held zero and has plenty of intensity adjustments for various light conditions. Nothing fancy but it's perfectly functional and is a good fit for this gun. And for the price (I think it was $65 from PSA) it's probably pretty hard to beat. The charging knob on this Gen 3 gun is much easier to retract than it was on the Gen 2. It can also be 'slapped' HK style to charge the gun. The cross-bolt safety is a little awkward but it's easy to get used to. Mag changes are easy even though the mag release button is really narrow. Unlike the P15 this one protrudes plenty far enough and mag changes are a piece of cake. I really like being able to fold the gun up and leave the optic attached. I'm glad KT figured it out for this gun. Side-folding would've been easy but the folded length of the gun would've been much longer, like the S&W. This one's a keeper.
