FWIW 1st gen 97Bs have a single-position external bushing.  It's the same as the one in Camaro400's post, but blued.  The bushing only fits in that position (obviously), and it has little slack, enough to move it for easy disassembly. 

From what I can tell, the 1st gens were meant to use standard 75/85 recoil springs (nominally 14 lbs.), as opposed to heavier aftermarket springs.  When I tried heavier springs (like 16 lbs.), they would tend to drag on the frame until they took a set.  I bought mine in 2001, so I don't remember all of the details.  I do remember shooting heavy springs (16 lbs. and higher) in a 75B to "set" them, then trying them in the 97B. This was a long time ago, and I have zero experience with more recent 97s.  I think I am using a 16 lb. Wolff spring now. 

I would look at older posts and the archives.
That's a CGW 1911 bushing.

Got the E mail this morning CZ is sending me  my original gun back repaired  this is the explain

" Work Performed: Pistols trigger pin appears to have been removed before. Right side trigger bar spring out of place between trigger bar and frame. Adjusted and placed trigger bar spring in proper position. Test fired good "

That prob happened when my bud removed the CGW trigger kit and firing pin ect trying to fix the original problem before I sent it back to CZ so have my doubts
unless the Tech fired 2-3 mags before the problem would occur anyway they originally said the gun was unrepairable and were sending me a new one once they were available guess not available or they just went to work on it.

Stay tuned and will shoot it  straight away with the 5 mags I have loaded and ready , I doubt I will send to CGW for the bushing Mod till I am for sure the problem will not come back to haunt me again as I am sure that will void the warranty I have left .

I would call them directly and ask what changed from the original determination.

I haven't had to buy recoil springs for a 97B or a 75B-based gun in years, so some of this may have changed.

When I was shooting CZs a  lot, the Wolff CZ springs were really NOT CZ-spec springs, but springs made for the Tanfoglio version of the CZ design.  The Wollf springs had to fit the larger diameter Tanfoglio/Witness guide rods, but they worked OK in the CZs.   

Springs for the Browning High Power seemed almost identical in size/diameter as the CZ factory springs and offered some weights (including a variable rate spring) not available for CZs.  That's all I've used for the years that I was shooting 75Bs and my 85 Combat.  (My CZ and CZ-pattern gun collection is much smaller, nowaday, but I've still got a parts bin with a variety of both diameter recoil springs stashed away.)

If nothing has changed, and you're using a stock guide rod and a WOLFF spring, it's not going to fit the recoil spring tightly; if so, you will see and hear some rubbing inside the dust cover and see marks on the on the underside of the barrel.

Got it back this afternoon took to range fired my 5 mags of blazer 230 ball and a box of 50 SB 230 ball no problems  100 rounds good ! 

I put my upgraded recoil spring and guide rod after I cleaned when I was done but not going to put any other internals in till I get 500 rounds thru it

trigger breaks at 4.5 so it's livable , It shot decent but in it's absence I acquired a DW Bruin in 45 almost like cheating in comparison and stayed with the company

If it stays together I will do the CGW Bushing next.

As I mentioned in a previous post, I used to "set" springs for the 97B by shooting the Wolff Tanfoglio/CZ springs in a 75B.  I actually got this idea from you, Walt.  (This is FEG with a new username/ID).  I've had a 97B for over 16 years, and I have never had any rubbing wear from springs. 

To clarify, there were no aftermarket springs for CZs about 10-20 years ago.  You could either buy springs from CZ-USA (weak/undersprung), or buy aftermarket springs from Wolff that were really intended for Tanfoglios.
