The other side.

Is this typical from STI for a bald slide? I'll be tri-topping this one so it doesn't matter,but I don't even know how I would start to get these huge lines off the radius. There is one on the other side and top as well.

I don't throw any brass in the trash. Don't you have a scrap bin?

I've loaded that bullet at 2.260 in pmags with no problems.

I don't really see where it is sticking out. Does It feel uncomfortable? It will all need to be refinished if he has to do more blending. Is that nitride?
-
Have you looked at dawson precision? I think they do free shipping over $25.
-
I've fit a few kkm's and have been very happy with the results, especially accuracy. I've got a bull barrel on my bench waiting to be fit now.
-
I was under the impression that the nitride process involves temps upwards of 1000 Fahrenheit. I don't know what the implications are for the thin metal at the tip of a sear nose. I've got several nitrided sears and they seem to be fine.
-
They have beefed up the spur. The nitride makes the thin parts brittle. I wonder about the nitrided sear noses though...
-
Careful on an egw hammer. They are now warning not to nitride their hammers. They can break. Ask me how I know.

I get what you are saying now. Thanks for taking the time to explain it.

I'll have to do another frame if I go that route, since this is a commander build and I can't find an STI commander slide. I'm trying to visualize how reducing the bottom slide rail thickness or lowering the bottom ways in the frame affect the timing. It seems like the slide wouldn't sit any lower because it is limited by the frame rails in the slide ways. I can see it if I reduced the top deck. Can you help me understand that relationship. Thanks!

It can, but it depends on the stacking tolerances of the slide. If you have a large gage pin, even a .250 if that is the largest you have, grab it. Put your slide upside down in the vise and insert the gage pin so that is lays in the "bottom" of the slide where the slide lugs are located. Take a depth mic and tell me the measurement from the bottom of the slide rails to the gage pin (don't forget to add in the diameter of the gage pin).
Ok, I used the dro on the mill and averaging tenths I get .8455 from the bottom of the slide to top rear top lug face closest to the breach.
I appreciate everyones help.
I've got another sti frame that I measured .112 with a gage pin.

I measured with a gage pin and got .110. .111 fits tight on one side and not the other. Does STI sell a commander length slide? That's the plan for the build. It looks like there is about .010 at the bottom of the frame slot before it is flush with the dustcover. I could try to take .004 off the bottom of the frame and .005 off the slide, but that could be easy to screw up the frame. Will a staggered tooth keyseat cutter do what I need? Would taking .009 off the bottom of the slide really be detrimental to the gun?

Sti 2011 frame and Caspian slide.

I had to look it up again. It's actually .114 and he states this is the minimum vertical slide rail height. My frame ways are .109 in height. Slide is .119.
-
I'm about to start another 2011 build. Have any of you used a keyseat cutter to open/lower the slide rail ways on the frame instead of taking all the material off the bottom of the slide? It looks like I'll need to take almost 10 thou off the bottom of the slide. I thought kuhnhausens book advised to not go farther than .113 on the slide? I need to look it up again to be sure. It would certainly be easier to take it off the slide to avoid making an error with the keyseat cutter.
So, what's the most you would take off the slide before you would modify the frame? Strictly talking about the slide rails on the frame ways.

I know this is old, but I'm interested too.

I'd go black nitride through H&M. It is not a coating, it is a chemical process of which the end result is a black color.

She Is starting to break in real nice. The accuracy is insane. Totally worth the wait. I think she needs a twin ??
thanks for all the replies.
How long was the wait?

Both sides, one is slightly larger.

I agree with Vespid. I have run XM-193 out of one of my 18" guns that chronoed about 3200 fps. It was pretty much spot on with the bdc. It was also 2.5 moa ammo. The same gun will shoot heavies under 1 moa. So there are positives and negatives. At my next match I'll be using 69's zeroed at the 300 hashmark. My 55's fall in line pretty close for anything out to 300. I know my holds exactly out to 500 confirmed on paper. I've even started a stage with 8 or 10 55 grain bullets in the top of the mag just to hose a few papers before I shoot longer steel. I have no idea why that $1.50 of savings is important to me.....OCD?

My edge has a tight chamber and doesn't like lead bullets. When I talked to STI they told me to just use jacketed. In other words, no help given.
-
The heavy bullets may flash the target slightly better, but I've never had a problem with 55's. When I run heavier bullets it's because they are more accurate.
Chip in slide locking lug, should I be concerned?

How does the barrel locking lug look?
