The breechface cut for the striker tip [the FP hole] was cut too high and a little bit to the right also. They'd have to be blind not to see it if they shined a light down the striker tunnel. Also there was no debris hole drilled just aft of the breechface, so air was not flowing freely around the striker as it travelled.

Hunter - the ipsc-smith down here - copied the debris hole angle and location from my stock G35 slide and drilled one in the Caspian G17.

I took the striker tip to a grinder and changed the point so that it hits lower - kinda like shaping a 1911 long ejector. That centered up the primer hits.

Then John Nagel called and said to look for burrs in the breechface [found some] and see if the bottom of the striker tip was dragging on the FP hole - it was. Filed off a small amount of striker there & everything's been fine since. I'm real picky now about how the striker assy works after it's been reassembled - see "Ignition Test" over in the Glock forum.

Somewhere on here I said that the accuracy was about 3/4" at 25 yards. That was a mistake. Last night I shot David Tubb's way and got 2 groups in a row under 1/2". Zero 125gr JHP bullet [the R162] and 8.25gr of HS6, 1.150 OAL.

I don't think anyone with a frame-mounted dot gets that kind of accuracy from a Glock, but I could be wrong.

I took off the bandage-wrap grip because heavy doses of dry-fire ripped it up pretty often. I shaped some old wood grips and glued them on:

Wow! Nice groups. Was any accurizing work done besides fitting the barrel?

Also, what is David Tubb's way?

[eric nielsen]

Brian Hawley fit the KKM barrel, Beven Grams machined the slide for the Docter sight, and that's all the accurizing you need with a slide-mounted optic. The Caspian slide fits really tight to the Glock frame but that's not a big deal unless you mount a sight on the frame. Saw something on a video where D. Tubb hooks his finger from the outside in but really only tried that slow-fire.

Didn't really want to part with the most accurate gun i've ever owned, but it now belongs to Mike Killian. I did a few more mods plus a nice 1.75lb trigger job. Here is what it looks like now:

Did those little ports where the front sight used to be do much?

And what sort of weight is that on the accessory rail?

[eric nielsen]

The ports help hold the gun flat during recoil. This gun came that way but every other barrel that I've ported, the gun shot flatter. The weight was a blued-steel weight from Jentra, I cut & grinded on it until it was about 2oz, not the original 7oz. With an empty mag the gun weighs 34oz.
