Kahr 1927a1 Range Report
Posted 01 December 2005 - 04:38 PM
Anybody know of a really good aftermarket extractor? Anywho I was really hoping to get in 300rds! More to come.
I think I'm going to do a little more work on the chamber area, and thinking of changing the angle of the chamber entrance. Going to make this thing super reliable! That well show Kahr
Thinking ahead; Trim and stretch the recoil springs, and adding a buffer Any input would be great!!!
Saw that freaking barrel down!!! Just kidding, but might consider a 10.5" barrel including all the hoops to jump through. Does anybody know exactly what hoops I need to jump through? I have a CCW, so I'm good with the county/state/& feds, if that means anything?

Adding a buffer may shorten the length of bolt travel and thus increase the bolt velocity which may cause even more rapid destruction of the extractor.

What do you mean by that exactly?
Welcome to the forum, by the way!
What kind of ammo were you shooting when the extractor broke?
(Deja Vu <-[hears wolves howling])
And If I understand correctly you took the barrel out?
You did headspace that correctly when you put it back in, right?
With excessive headspace, you might have been headspacing off the extractor only, which could have broke it as well. That means the cartridge was held to the face of the bolt by the extractor only, and the firing pin could have bashed the extractor excessivly. (Or something like that...)
Go easy on the Dremel and spring snippers untill the gun has gotten a few hundred rounds put through it and it is broke in.
(Cause you don't want it broken, just broke in... )

When I hear the words "Taking the barrel off", and "Changing the angle of" on anything having to do with guns, I cringe and hope that person has quite a bit of gunsmithing under his belt.
I get these visions in my head of pipe wrenchs and excessive headspace dancing through my head...

Anywho, got back from the range today and I would love to report that the UN-Kahring is almost complete
210rds flawless, aside from the usual screws falling off or coming lose. Heck 100rds where through the new and improved UN-Kahred drum I machined on hahaha this morning.
OK where to begin; Well getting the barrel off wasn't all that hard really.
drum roll please ..... Vice-grips , a giant Vice in my garage, and some heat. I'm not saying I didn't scare the ribbing a little, but a piece of leather helped prevent to much damage. For those who are thinking of doing this, kahr uses a crap load of red loctite so you'll need a bottle of map gas or what ever to liquify that stuff.
I polished the chamber for a little bit to remove any machining marks, and opened it up just a little bit. I than slightly ramped the left & right side of the barrel. I however didn't cut into the webbing support, so you can breath now.
The only issue I have left is a few more thousands off the pawl. As you remember I machined the receiver down where the mags insert without opening up the catch hole. Well that doesn't mean I didn't have to mod the mags. I did have to remove material from the mag & follower to allow the trip lever to seat. However when the gun starts to get hot, It likes to lock the bolt back with one round left, and once today with about half a mag full. It's looks as the bolt & pawl are a little to close and than adding the vibration, heat expansion, and receiver to frame slop that could be the problem?
Almost there guys!!! and I was very happy that drum worked as well as it did today.
I also had a chance to break in a new Bushmaster AR-15M4A2 I bought last week. Two hundred hand-loaded .223's--- flawless!!!! hello Kahr, do you test your guns before they leave the plant???
Almost forgot, the new load I worked up for the UNkahr 1927A1:
Winchester FMJ-RN 230gr
I made the Tommy's look good today guys, but man it's been a ride! Dang I could of done better with a parts kit, then Kahr! SAD
Broken bolt, broken extractor, non functioning drum, hand grip off center, chamber out of spec, the list goes on!!! What defines a lemon???

Sure sounds like you got your smithing together, but I would be real careful
about trimming those recoil springs. Could wind up with a cracked reciever or worse.
Best and easy to do like Lionhart suggests, just get a set. They work great and have been
put through the wringer.

I'm going to get a parts list together (Spring kit for one!), clean up all the rough edges on the receiver, finish up any tweaking thats left, and a little polish on the frame components tomorrow and call it a year

Scaring me a bit here...If I got it right, you removed material from the mag well area of the reciever to avoid having to modify the Latch hole in your magazines...and ended up with a modified reciever that you have to modify the magazine lips and followers to get the trip lever to seat? Did I mistake something?
Not trying to offend...just trying to help...Modifying the magazine catch would have been the way to go here. Taking roughly .1 off of the top of the nub, while maintaing the contour, would have allowed the use of full auto magazines. On some you may still have to take a bit off of the follower tab...but not modify the reciever or mag body...no turning back now though. Guess it is just hindsight and dosen't help much now.
Good job on getting it to run...and the drum though. Hope this helps.

What the hell is up!!??
No F*%#@ing fair! Should I start putting aside money now?

|Should I start putting aside money now|
You will certainly regret it, if you don't!

Like everyone else that’s read this post. We need some clues, what about give us a date, not just the date, but in the ball park. Like Zamm, asked about putting money aside, can you tell us the price range?
