Adjusting CZ 75 D Compact PCR Rear Sight (SKU 91194)

[Sidecar2]

Out of the box, my CZ 75 D Compact PCR (SKU 91194) shot consistently to the left. Looking at the slide, the rear sight was obviously adjusted off center of the slide.

There is an Allen set screw holding the rear sight in place. It takes a 1/16" Allen wrench. Yeah, I'd have expected it to be metric, but my 1.5mm wrenches were loose and asking to round out the Allen head. I pulled out my bag of every spare Allen I've ever gotten with all the "some assembly required" kits over the years and starting fitting every little wrench. One fit exactly right. I miked it with a digital caliper and it read out exactly 1/16" (1.54mm, .0605", not .0625").

Anyway, I loosened the screw, then put the slide into my NcSTAR sight tool, which I had mounted into my 6" bench vise for stability. ($45 on eBay -- https://www.ebay.com/itm/Universal-Pistol-Slides-Rear-Sight-Tool-Glock-Pusher-1911-Handgun-SIG-Heavy-Duty/222379473021?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 )

The sight moved with difficulty, but I was able to center it.

Highly recommend you put the $45 into a sight tool. You'll use it more than you know. A couple of friends stopped by. Both of their Glocks had rear sight alignment problems. I whipped out that NcSTAR and fixed their guns for them in seconds.

Don't pound on your sights. Move them safely and reliably, with great accuracy.

I wish I would have read this before using a 1.5mm on my 75B today. I may have stripped it. Dang these small screws!

Just received this one from Washington Gun Works. Made in USA.

$40

Going to use it on my 75B then the 75D.

But for $5 more, the VISM looks pretty sweet.

Nice tool! My only firearm is the PCR and will soon do a front and rear sight replacement. If I had a number of pieces, then I would invest in this.

I have a simple question to ask sight tool manufactures, WHY DO YOU INSIST ON USING COARSE THREAD SCREWS OR BOLTS, A FINE THREAD SCREW OR BOLT EQUALS  LESS MOVEMENT OF THE SIGHT WHEN MAKING SLIGHT ADJUSTMENTS. Think about it, for example ...1/2x13 thread or 1/2x20 thread...whice one moves less per each revolution  of the screw/bolt.....the 20 threads per inch ...and of course metric threaded  screws/bolts offer different thread pitches too...

Coarse threads are stronger in this type of application. Fine/superfine threads would not have the lifespan of coarse threads and would weaken and strip much sooner as anyone who has changed sights knows some are exceedingly tight.
Yes they could make these tools out of high end hard alloys that would be very strong and you would have a sight tool that cost 900.00 as well.

The price on that NcStar was JUST reduced to $41.56: https://www.ebay.com/itm/Universal-Pistol-Slides-Rear-Sight-Tool-Glock-Pusher-1911-Handgun-SIG-Heavy-Duty/222379473021?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 )

However, some reviewers on Amazon have reported that the metal on these broke during use. https://www.amazon.com/NcStar-VTUPRS-Universal-Pistol-Sight/dp/B01HU4NNDE/ref=sr_1_1?s=sporting-goods&ie=UTF8&qid=1530722248&sr=1-1&keywords=vism+sight+pusher

I am sorry, but I do not agree with fine threads wearing out sooner. I have a friend who ran a machine shop, I will get him to check his manual and If I am wrong I will change my response, but I believe I am correct.....I think....

Go back and read what I stated.The tool would have to be built of HIGH quality hardened alloys to hold up in that configuration which would make them very expensive. I've used many pushing,pulling compressing type tools in my job over the years. They are nearly always coarse thread and those that were not failed early. Those that lived were high quality metals and they were expensive to purchase.
Simple fine thread bolts coupled with soft aluminum will not last long. Some of those sight tools are so cheesy and cheap they fail with the first use on a stubborn sight even with coarse threads.

The VISM tool has a polymer pad for the bottom/base to protect the finish on the bottom of the slide.

It has a polymer pad for the clamping plate that comes down from the top of the tool to press against the top of the slide to protect the finish.

It has two pairs of polymer pads for the side clamps (for slides that are not flat/square on the sides, if your pistol is made that way) to protect the finish.

So far, the only pistol I haven't moved a rear sight on is an XD and those are supposed to be notorious for having almost impossible to move sights.  No matter how tight I got the top/side clamps the slide would begin to twist/lift on the side the adjustment tool was putting pressure on before the sight would move.  I guess the polymer pads were compressing some on the one side and the top (I'd removed the polymer pad from the bottom to see is that would help but it didn't.)  I've used mine to remove the rear sights and installed night sights in five CZ75 Compacts/P01s, two full sized CZ steel framed pistols, one P09 and two P07's.  No issues with the CZs, so far.

Just to add to this I did some research and there are some tools out there with finer threads but as I suspected they are better quality and with that comes the higher price. You just ain't getting a good tool for 50 bucks. Not one that will stand the test of time anyway.

I'm still using my old B&J500 sight tool-  Has anyone changed the rear sights on a H&K VP9?  The sides of the slide are not parallel, the grippy rubber things get in the way of securing the slide down, and it nearly drove me to dipping snuff!

[M1A4ME]

My nephew has a simple/cheap sight pusher/tool.  We managed to change the sights on his XD Compact.  By the time we were done the bolt was stripped out and we removed it.

I went to Lowes and bought a grade 8 bolt (also coarse thread) and installed it in the sight pusher tool.  At the time I wondered if the installation of the grade 8 bolt would result in the threads in the frame of the tool being the next thing to strip out.  He hasn't used it yet, so we won't know till he does.

Something has to give when enough force meets and object that doesn't "want" to move.  Sometimes the designers take that into account and design one piece of the unit to fail first, vs. a catastrophic failure or the failure on an expensive part that may be hard to get.

I have a H&K VP9SK, which, as you know, has a lever you rotate to remove the slide. I reassembled the gun one time, pulled the slide back, expecting the slide to engage like a Glock or P10C. It didn't engage because I didn't move the lever back into position.

The slide flew off the frame and hit my tile floor. The rear sight had moved off center. Dang. (To add insult to injury, I did the same maneuver again at the range, this time dumping the slide into the dirt. Oh well. Glad this forum is anonymous....)

Anyway, I tried drifting the rear sight back into position and dinged it up a bit before giving up.

That's why I bought the NcSTAR tool. It held the VP9SK's slide tightly and allowed me to move the rear sight back into position accurately.

I thought that was the end of it, but I've used the tool several times since. So far, it's a good investment.

I removed the rear sight on my Glock 43 and inserted a dovetail platform to receive a Vortex Venom red dot.

I have a simple question to ask sight tool manufactures, WHY DO YOU INSIST ON USING COARSE THREAD SCREWS OR BOLTS?

My NcSTAR uses what appear to be 3/8-16 pitch threads. Yes, they are NC, not fine.

In practice, they allow sufficient accuracy to make very slight adjustments. I've now removed, replaced or adjusted rear sights on five different guns and it's worked fine.

One instruction that is stamped right into the aluminum frame is a pictogram reminding you to OIL THE TREADS. You're dealing with steel on aluminum, with both under considerable pressure. Oiling the threads lets everything work a bit easier and protects from galling the aluminum.
