Rail machining quality on older 75's?

[jdc0589]

I was browsing a local gun shop yesterday and found a pre-B 75 for $330 (one mag, no box). The exterior was in great shape, though somehow I didn't notice if it was blued or poly, though I remember the finish being a little to "satin" to be blued. The only thing I know needs to be replaced is the trigger return spring, which is completely shot (I have a spare from CZ-Custom if that works on the older 75's).

I popped it apart I was pretty appalled at the quality of the machining on the slide rails. It's not like it makes a huge functional difference, but I just wasn't expecting it. Is this common on pre-b 75's or was this one just especially bad?

i have 1 NIB Pre B and 3 police/LEO tradeins.  they all have rough rails.

just an fyi, even the newer ones can be comprabable in quality.  its the way it is.

My '92 Pre-B is quite rough on the inside as far as machine marks are concerned. The inside of the frame is really, very roughly finished. Likewise, the rails and slide are also not machined to the same level of smoothness you may find on other brands of pistol.  That said, the gun is dead reliable and shoots way straighter than I do.

When I got the gun and saw how rough the sliding surfaces were, I hit all those contact surfaces with a fine India slip stone, which flattened them and seemed to smooth the racking of the slide. However, I may have been fooling myself with the touch-up work. It could just have been better lubricated after I finished smoothing things than it was before I started.

If I could find a nice one for $330 I would buy it. 

Note that I also owned a Tanfoglio small, polymer-frame clone. The slide on the Tanfoglio was way better finished than the CZ's slide.  It did not shoot any better, though and I found the ergonomics a bit inferior for my hand.

My 1985 Pre B was very rough and was most notable on the rails. The 1990 from Robertsons was quite a bit better. My 2005 B Model had interior finishing that was equivalent to Sig or Beretta's offerings. Major difference in the interior finish from the communist era to the capitalist era.

Just for the record - I've had three CZ's with the grasping grooves machined into the slide rails.  I sent a picture to CZ-UB and told them poor quality control will hurt their brand.  I don't know if they still have these kinds of errors anymore.  This was on the CZ75B stainless with upswept beavertail and the SP01 - so both pretty new models.
