I voted Kel-Tec. I'd leave the AR builds until the shockwave dies down some, or hoard them and sell them for gold and gummybears later - I think the G19 is fine, and unless you have a good reason to get one of the others, stick with whatcha got. 1911s are cool, but I wouldn't get one simply because I didn't have one, especially if you've already got a Glock you like.
Of course, many will debate the point of a pistol caliber carbine anyway, but I think for commonality of magazines it would be a fun carbine to have..
I voted 1911 but that's a personal decision since more than the look, I like the way they feel in my hand (at least with the arched mainspring housing).
I would get the Kel-Tec, after I thought about my vote for AR build. I look at the Sub-2000 as one sort of stop gap. If something crazy happened and pistol carry laws were somehow erased by our new Obamination, this qualifies as a rifle and can be legally carried in a small backpack, without arising suspicion. New sales on both AR and Sub-2000 would probably be limited with another AWB.
Well, you already have a G19 which is a good mid-size 9mm that can be pressed into fairly universal service. Pistol caliber carbines have never made much sense to me (as much as I've tried to justify the purchase of one for fun).
finish the ar build, you can never have too many ar's, and if the need arises, you can always sell the extra lower, and still have 2 configurations to put on your one remaining lower
for you, i'd say finish the ar. do it in 5.56 and then get the kit and top end for 9x19.
for me, i'm stocked up on all the others, but would love to have the kel-tec.
I have always liked glocks and XD's but after shooting an all steel 1911 in .45 acp.......well there is only one thing better and I dont want to get banned
1911 !!! But if you feel the rifle itch they have a conversion barrel that the 1911 slides into and becomes a rifle. I'm not sure what its called but it sure looks neat!
Well, I just put in my order to finish my AR. I'll be sure to post results after I get her done.
Went with a 20" Del-Ton kit. I already had the LPK in the lower, but the difference in price between just the upper and the whole kit was easy to have the extra parts in my hands.
