Broken AFTEC

Recommended Posts

Just wondering if anyone else experienced this; in the middle of a practice session I started getting FTE's. I tore apart my slide to check the extractor, and low and behold there's a crack in the hook area of the AFTEC. Anyone experience this before? I only have about 4-5k rounds on the extractor. The gun hasn't had any extraction related malfunctions at all up until this last session. Swapping the stock extractor back in fixed the problem. I fitted a new firing pin stop when installing the AFTEC. Gun is a .40 Edge. Did I just get a lemon, or is this common. My faith in the AFTEC has been shaken a little. I'm just thankful that it didn't crap out on me at the Nationals.

The only aftec that failed on me was hardchromed and the hook was just ripped off. gone. leaving a jagged flat area. It only took about 1500 rds to break.

The only other problem I currently have is some mislabled packs. I ordered SC and got SA. I Returned the SA and I got a .40S&W! I contacted Derek, and he says to send him all 3 and he'll sort em out and get me what I need. The broken one, a used SA that was the wrong package, and the .40 which I could just keep as I need one for my new build. Derek stands behind his products, and as I look in my gun safe and workbench, I must have $1000 in Aftec! Derek even exchanges extractors that were ground on, Though it clearly voids the warranty.

I'll bet that's why the instructions say, "Warning: Do not hardchrome the extractor." :rolleyes:

I'm sure it is. It's how I bought the gun. EVERYTHING was hard chromed but the sear, leaf, disconnector and trigger bow. It was a very frustrating & expensive lesson. Now I only do frames & slides. I'm not blaming Derek in any way for that incedent. I'm just trying to convey what NOT to do.

I couldn't quite see the crack from the pic, but make sure the nose of the AFTEC isn't contacting the barrel when the slide is fully forward. I'm sure Derek will replace it. R,

The crack is right where the thick part of the extractor tapers into the thin part (pardon my terminology). My digital camera has poor macro resolution so the crack is pretty much invisible in the photo. When I installed it the nose of the AFTEC was clear of the barrel. The AFTEC was not modified in any way; the only mod I did was fit a new firing pin stop which wasn't even necessary as the AFTEC functioned perfectly with the stock FPS. The pistol has since been sold with the stock extractor put back in.

My new gun is being built now and should be ready in a few weeks. I'm divided between upgrading the stock STI extractor to an AFTEC or a regular type heavy duty extractor. The gun was a special package deal only available at the Nationals so my options are very limited. Either way, the extractor installed in the gun will be my spare.

Actually they DO need fitting. The firing pin stop needs to be chamfered on the corners to allow the extractor to move in and out. The FPS also needs to be sized to the groove of the extractor. If the FPS is undersized the extractor can clock.

I thought he was already replacing his FP stop. Why not contour it while installing your aftec? I would think someone who can replace their FP stop can figure out how to fit their extractor. It's not like you need an extractor tensioning tool. I see where a pair of calipers would help.

If you are worried, call Derek. He can either walk you through it, or do it for you.

You radius the FP stop, check that the nose isn't hitting the barrel (shorten as necessary) and then trim the back where it sticks out of the slide. I use a couple of tools to trim and shape, but they're not complicated. No need for calipers. R,

+10 give Derek a call. He even replaced one i screwed up for free. He fitted it for me too.

How much did it cost for him to fit the AFTEC, and what was the turnaround? I may have Millenium fit an AFTEC in my new gun.

There was no charge to fit my extractor. ust give him a call and he will let you know. www.mcguns.com

The Calipers are to "press" the springs lower! :)

You'd use a measuring instrument for that?

If you leave the springs alone, install the AFTEC, then hand cycle a mag or two full of dummy rounds through the gun, the springs will take a normal set, but not be overly compressed. Just squeezing them with pliers might compress them too much. R,

You use the calipers to press em down flat to .125. I wouldn't use my starret or my mituyto digital calipers. That's what harbor frieght tools are for. These are in the instructions that come with the aftec.

The problem with the instructions is that not every extractor tunnel is exactly to spec. If you simply install, then run some dummy rounds, they'll take the exact set needed....no more, no less ;)

I did like Bart said, but i compressed mine a lil different, ended up squishin the front one, and leaving the back one alone, hand cycled rounds to be sure, then fired a few with each step, seemed ok, then i went 1 step further, by doing a lil 'light' filing on the radius where the round cams up into the extractor, its gobbled up 1000's or rounds thus far...no probs
