Had an SA35 for a while, but did a little "serious" accuracy work. Not concerned with being off to the right, but the vertical stringing is a problem. When I got home, I measured the barrel and slide hole. Barrel is .498, slide hole is .518 so 0.020 oversize. Any cheap easy ideas to gain 0.020"? Silver soldering shim stock, turn barrel and sleeve,  just but a new barrel cut to a closer size?

It's just a pinker, but want it to be better than this...

SA will fix it.  They've been very good to me.

I believe that pistol is within tolerance. I’ve sleeved the muzzle to get more OD on pistols like that. Helps a bunch.

I was thinking they wouldn't let it leave if that wasn't tolerance. Big tolerance, but it's a $600 highpower so not surprising. 

Jon, thoughts on clearance to avoid binding? 0.001 or is more needed? Gonna try something... different...

Thanks in advance

You might be interested in this thread:

My first SA-35 shot fine - for up to 10 rounds.  By 25 rounds the holes were off the backing board.
My replacement SA-35 has an 8 pound trigger, and horrible grouping.

The image near the bottom, of the target provided by SA for my first gun, probably shows what the gun should do, and all the reviews seem to love it along with its 5# trigger.

Oh well.......

I recently checked out a $599 Girsan Hi-Power clone at my LGS. The slide/frame fit was very good. Plastic grips. I could not determine the barrel/slide fit, I did not feel anything noticeable as far as "play" is concerned, but I did not make any measurements. The DA trigger was pretty typically heavy and rough. I was hoping the SA trigger would be nice, but it was a long gritty pull. If they use Browning or FN spec'd parts maybe there is a way to improve it? I don't know anything about Hi-Power triggers.

Hi-Power triggers are a pain to do, but can easily get good 4# pull. 3-1/2# takes a bit more work. I’ve never used aftermarket parts, could be easier.

You might find your answer here:

I thought about this - around $200 for parts, and around $100 for my gunsmith, and my SA-35 (if they ever send me a good one) will work as well or better than all the reviews indicate.

(I think I gave up on this gun, and bought a Springfield Armory Range Officer Target in 9mm.  I'll have it this coming Wednesday.  
No idea if I will send it off to Dave or one of the other bullseye gun experts to make it shoot as well as I can afford.)

I've been reading about BH Spring Solutions for half a year now, and watching their videos.  Very impressive.

Jon, with your ability, I think you can do the impossible.  If you have time to look over the link I just posted, do you think your update would accomplish the same?  If so, and if Springfield exchanges my gun for a good SA-35 with the proper trigger pull, and a test target like the one I posted, maybe I'll contact you.

I lightly stoned the hammer to remove the bur and replaced the sear with an egw sear on two sa35s now. Massive improvement in trigger feel. A bit of travel, but its smooth and you don't have the "bump" in the trigger feel that both had previously.

Mike,
Not accepting non-1911 work, have it piled high!
I just read your link. Those guys are snake oil salesman. Clean gun, install SPRINGS only and return to owner. They probably inspect it and then write up feed ramp needs polished, extractor tip needs corrected, blah blah blah to get more money out of you. 
Some guns do ok with spring only kits. Doubtful that Hi-Power pull feels any better, just lighter.
My 2 cents…
