Quick Review: Rock Island 1911A2 .22TCM/9mm
Posted by blackcampbell under Firearms | Tags: .22 tcm, rock island .22 tcm, rock island 1911a2 |[6] Comments
So I got a hold of a Rock Island 1911A2 .22TCM today and had a chance to take it straight to the range for a break in. I only got 100 rounds of .22TCM and a box of 50 9mm through the gun, but it was enough to get some initial impressions on the weapon.
First, the look of the pistol is very nice. Unlike the usual natty RIA finish (very practical for a workaday gun), the TCM is beautiful with a nice black to the receiver, the underside and the flat top of the slide. The sides are polished and look a lot like the Kimber Eclipse, giving it a nice black on silvery gray two-tone. The fit and finish are premium quality — easily on par with much more expensive guns. It is a wide-frame, double-stack 1911. More on that in a moment. There are adjustable sights that work well, but a white or red dot on the front sight would have been a plus.
The grips. I know a lot of people like the wrap-around finger groove thing — I think it sucks. And blows. At the same time. Some complain about the look, but the fit was fine — they just make the gun a bit too wide for me, and the finger groove crap always messes with my natural hold on a 1911. There are almost no options for the pistol because the grip screws are just a smidge different from the Para-Ordinance A2. You can use the P-14 grips, but you have to dremel a bit on the screw holes, apparently. There are VZ Grips for the pistol, but they are available only in black through Armscor. I consider this a bit of a “lose” for the gun, but not enough to naysay buying one.
The upside to the double stack 1911: 17 rounds of 9mm or 18 rounds of .22TCM. The pistol is heavy — it’s not a great choice for concealed carry, but it isn’t a bad choice for backpacking, open carry, or the like. The magazines fit well, and mine functioned flawlessly. Another downside — it doesn’t seem to fit in a standard 1911 holster, or at least not the SERPA I have. Weight is about 41 oz., so about a quarter again heavier than, say, the Kimber Pro Carry II’s 35ish oz.
Function: Oh, but this is a great gun. For the $600 or so you’ll shell out for the TCM, you get one of the single best triggers I’ve used on a 1911, which means better than just about anything not costing you $2000+ (and even on par with some of those.) It broke at 3.5 lbs. nice a crisply with no creep at all. Reset is quick and loud enough that if you watch some video, you will hear it. The trigger and hammer are skeletonized, and there is a nice beavertall grip safety. The weapon ran all of the 150 through it with no malfunctions, save for me accidentally putting the safety on while shooting. (Lefty…)
Accuracy: 2 inches at 15 yards, free hand, taking my time in 9mm and .22. Better at 10 yards. The groups were amazing, but I consistently shot a bit low due to the finger groove grips. (Seriously…hate these things.) I suspect I can do better in another trip or two.
Ammunition: Armscor’s the only people doing .22TCM, just like FN was humping their customers on 5.7x28mm for the longest time. Seriously, Armscor, here’s your winning friggin’ proposition — do an AR in .22TCM. Yesterday. Why, you ask? Because you get the same performance as the 5.7mm out of a standard-size grip handgun. The rounds I shot were chronographed at 2000-2060fps by one of the other shooters who frequents the range. With a 40 gr. bullet, that’s about 350 ft lbs of energy, or the low end of 9mm. With almost zero recoil — the 1911A2 weighs enough you get less recoil than the FiveSeven, and more accuracy because the weight actually make your hand move less and the trigger is lightyears better than the FN’s. (And I love the FiveSeven — carried one for a decade.)
Even better, if you can’t find .22TCM (as low as $17/box online, usually $22-25 in town), you can swap the barrel and recoil spring with ease in about a minute, and shoot 9mm. I did not try hollowpoints this time out, just crappy Federal 115 gr. white box stuff. No issues. It shot well with little recoil. Armscor — make some kind of AR or carbine that uses the pistol mags and a swappable barrel and you have a winner. Just do it. Yesterday!
The two big complaints I have are the obvious grip screw, hard to find alternate grips thing, and the lack of an indicator dot on the front sight. Otherwise, this is a better functioning 1911 than the two Rock Island .45s my ex-wife had, better than the CDP 9mm and the Stainless Pro Carry II from Kimber, better than the Springfield Armory 1911s I’ve shot (with the exception of a friend’s Yost-Bnitz modified Springfield.) It’s got a superb stock trigger, good sights that a bit of paint on the front post would make great, CZ levels of ammunition in the magazine, and comparable accuracy to my CZ-85 (which is excellent.) Fit, finish, and frills are all high quality for budget 1911 prices. And you can shoot two different calibers.
So is it worth it? Not just yes, but hell yes.

Four Years On, a Review of the MacBook Air 13″ (Late 2010)
Posted by blackcampbell under Computers | Tags: macbook air 13", macbook air battery life |Leave a Comment
I don’t see a lot of these around the internet, but like cars and appliances, it’s nice to know what the longevity, etc. of an expensive piece of equipment is likely to be.
My then-girlfriend bought me my first MacBook Air in October 2010, four years ago, mostly because I had so loved my first iPad she thought I might appreciate the aesthetics of the device and the small size and weight — important at the time, as I pretty much went everywhere by motorcycle, and it would fit in my tank bag. Here’s the initial impressions of the computer.
So, four years on, how is it? The body is still solid, doesn’t creak, and still looks great — no scratches or blemishes to speak of. The display is still clear and bright, with no pixels burned out. I don’t have quite as much need for the size, as I either work at home, or when the kid’s in daycare, which means I’m in the “cage” (car), but it’s still the most comfortable computer to use that I’ve owned.
Once I got used to the Mac interface, I found it worked quite well, although they really need to work on their help references; when you run into issues, you often have to go online and hit the Apple support boards to find answers. The Air has had four or five friggin’ OS changes since I bought her, and I suspect Yosemite — the latest — is going to see the end of support for the pre-2012 machines. That’s perhaps the one issue with Apple — they don’t do backward compatibility for more than a five or six years, then you are on obsolete OS and tech (the original iPad that found it’s way to my little girl is now in that limbo — none of the app she has are upgradable, and it can handle the new iOS8.) However, I’ve met plenty of folks still pounding along on decade old MacBooks and happy to not have the latest and greatest.
To that end — with Mountain Lion, the Air started having issues with video and running up the fans on the computer. For the first few months I didn’t even know it had them; I never heard them. The video card just can’t handle the new Flash and H.265 streams without get seriously hot. Even web sites with Flash would also run the machine hot and drain the battery. Up until recently, I used Chrome for most of my web work, but recently found the newer version of Safari was faster and did a better job of keeping the various ads from killing battery life.
As they’ve moved out the various OS, I saw negligible improvement or reduction in performance, battery life, etc. I was lucky and had none of the bugs that hit some of the machines for wifi and other problems, so I can’t comment to those that did. Yosemite was a sharp improvement in the user experience: you can make and receive phone call without getting your lazy ass up to find your phone (if you have a newer iPhone on iOS8), do text messaging the same, and their productivity suite has mostly recovered from the gutting it got to make it talk to the iOS version better. All the iCloud stuff is nice, but I don’t use it because I’m too cheap to pay for space, and too security conscious to throw all my data out where people can get at it easily. (I still pull the SD card with my personal stuff when traveling. Screw you, TSA.)
The older CPU is more than ample to handle most of my daily chores — i can have as many as six docs open, a few tabs on Safari, iTunes playing something that is stored on the external drive and have nary a skip in performance, although when it comes, it’s inevitably iTunes that’s the culprit. Battery life at 300 cycles, four years in, is about 6-7 hours doing some writing, some web surfing, and the like. If I turn off the wifi, it jumps about 2 hours. The original 6700 mAh is now 6067mAh (90%)…that’s pretty friggin’ good for a four year old machine. None of my old laptops had a battery survive more than two years before they had to be replaced. With the curve these batteries have, I can anticipate another year to two before battery failure.
So if you are in the market for a MacBook Air and don’t want to pay premium prices for a new one, a used laptop looks to be a good buy; if you want a new one, you can expect to keep it for four to five years before it slides out of the support stream…and even them should be usable. That’s only rivaled by my original Compaq from the late ’90s, and the 10″ Dell Inspiron I knew was still running like a top at six years old when I saw it last. (Sold it.)
