Locked breach idiosyncrasies?

[Newman31Bravo]

No firearm should fire out of battery unless it's defective but please don't push it back and try to fire a round with it. If you push it back enough it should disengage the trigger. The point of my post was the treatment of a new guy that was ridiculed since his Kahr would end up catching in the re-locking process. It happens, more with weak springs then with new, but no one would address that with him. Yes, he did get belligerent, after a fashion but all in all I believe he was treated badly and so did some others. This was a treating someone fair, issue not a gun issue. If you want to prove it won't set back or if you want to prove it will, you will be successful.

Agree, the first guy to respond to him did not know how to read and it pissed him off rightfully so then everyone jumped on him. But thanks for the info bro I appreciate it.

Col., this is how I used to fit Bar-Sto barrels.

Most guys would fit them using a cutting tool inserted into the slide stop hole on the receiver.

I did not. Instead, I used a nice little jig, and a fine white wheel on the surface grinder to cut the "pin" part of the underlug.

The jig allowed removing, and replacing the barrel onto the surface grinder, with so little deviation, it didn't matter.

From there, the "relief" part of the underlug could be cut by the cutting tool.

All of that came after top lug fitment and hood fitment, of course.

.... why use the surface grinder....

The surface finish was essentially final. There was no roughness to the surface, no tool marks to "wear in". And, the amount of material that could be controllable removed was on the order of 1/4 of 1/1000 of an inch.

The tool cut relief was "feathered" into the wheel cut pin area.

Back to your observation -

To me, that would be IDEAL for a newly fit barrel and slide.

As both wore (the barrel more than the slide), I'd expect this to be a total non issue. It might take 500 rounds or so.... the barrels I fit were to bullseye spec, so...looks like you got a good shooter there.

I remember one really fun little faux Officer's. I had a Commander (not LW Commander) slide, who's inside was just smaller than the outside of the Officer's barrel I got from Irv at Bar-Sto. It was an easy fit to use the slide itself as the bushing. Then, the underlug was cut, and it fit tight. My good friend Handy Andy said "its too tight". I went with my gut, and left it as it was. Another friend KJ ported teh barrel with trapezoids, and then we cut the slide with big ovals to allow the ejecta to escape. Bullet lube on cast bullets would foul the bushing area. So... back to Mr. Surface Grinder, I put 12 "splines" into the bushing area, which was easy as there was lots of meat to make those splines. The result... the bullet lube... Rooster Red as I recall... would be forced out the splines and create a real mess on the front of the barrel, but.. it functioned perfectly. Eventually... the barrel wore in, and my friend Bob P got the gun as a parting gift.

Col. When the barrel drops down, as the slide moves back, will the firing pin still be aligned with the primer?
And, when the slide is rearward, just a smidgen, will the disconnector work as it was designed?

I think this is a valid question. On any properly designed gun, the firing mechanism is disabled when the gun is out of battery.

Now in the Browning system the barrel may move just a little down, not enough to unlock the slide. By that time, the out-of-battery safety should be engaged already.

I don't have a Kahr .380, but I have a Glock 42 and Browning 1911-380 and I experimented with snap caps a bit. Result is, Glock is safe: its firing pin block engages before the barrel unlocks. Browning is not: there's a smidge of a distance when the slide is unlocked, but hammer can still be dropped and strikes the firing pin. Naturally, the firing pin hits way off center, on the border of the primer cap. However, that may still detonate the cartridge if you're unlucky. Well, double unlucky to drop the hammer onto an unfired round first.

Edit: For the record, none of my pistols hang out of battery, including the .380 guns. I have an XD that did that if pointed vertically up. I replaced its recoil spring and that fixed it. I bought that XD used and put about 1200 rounds on it before I noticed. I agree that the guy who prompted the locked thread should have replaced the recoil spring in his CW380. But instead he pawned the problem onto the next owner.

I guess I should clarify too. When loaded my pistols do not get hung up but there is a little less tension at the end of the slide. I would say maybe the first 1/4" of movement.

As far as your slide issue, there is nothing wrong. When your gun is cocked with a round in the chamber half of your spring tension is taken up, that's why it's easier to move the slide back.

Remove your ammo from the chamber and dry fire your gun, releasing all tension on the springs. Your slide should be tight and harder to move back at this point.

If you feel something is wrong, give Kahr a call and send it in.

When the barrel drops down, as the slide moves back, will the firing pin still be aligned with the primer?

I wouldn't think so. The round in the chamber should then be tilted down too much for the striker to hit it.

Some are assuming this quirk to be a fault with the gun. While almost like balancing an egg, I can get almost any properly functioning locked breach gun to hold that set-back somewhere along that cycle of disengaging. Don't assume that it's all points along that cycle but only at a certain "balance" point. Yes, the inertia of the slide will take care of it but when you manually push it back and hold it motionless at the right spot there is no inertia. The point of my post has very little to do with this at anyway. My point was that a newbie asked a legitament question and was ridiculed and even told he needed to use a holster (What) and everything else. I think the poor guy sold his Kahr because he assumed it to be broken. Point of post; Don't ridicule someone for asking a normal question.

I did see where anything said by the members of this forum could have been construed as ridicule. The OP claimed to have years of military, gunsmithing and concealed carry experience. This wasn't the first time that he had jumped down someones throat with whom he disagreed. His gun was pawned, he's gone and I don't think that he'll be missed. Nuff said.

Agreed.
