97B question

[Pecos Bill 1911]

I would like to replace my plastic guide rod, and am looking at the JackAsh Custom Shop's stainless guide rod & Wolff spring combo. I would like to know what spring tension would be best to get and why. He lists the tensions from 16-22 pounds. I do occasionally like to shoot Wolf/Silver Bear ammo, and I know it can be a little hotter. Best Wishes! Pecos Bill out.

Quoting from Wolff's website, 16lb springs are recommended for CZ97s when using hardball.

Hope that helps. :)

I read a thread where a guy was using a 22lb spring and saying that his 97B was shooting tighter groups and with hotter +P ammo. Is a spring that heavy too hard on the slide? Best Wishes! Pecos Bill out.

I use a 16# Wolff spring with a 97B to shoot hardball with. I think anything heavier than that is way too much. Remember, recoil springs do not "soak up recoil".

CZ-USA's gunsmith recommends 16# recoil springs in both the CZ75 and the CZ97.

Good shooting,

So if CZ recommends a 16lb spring, then why would someone want to install up to a 22lb one? Could it damage the slide? What would be the advantage to having the extra tension? Best Wishes! Pecos Bill out.

There are others here better qualified than I, but since no one else has replied I will take a shot.

I would only use a spring greater than 16# if I were going to shoot a lot of +P ammunition. A 16# spring should be more than sufficient for standard pressure 45 ACP ammo. In my opinion, too high a spring rating will cause possible damage to the slide stop pin, as the slide will return to battery at a higher speed.

Good shooting,

Mike

Forget about the FLGR too.You do not need it.I tried one for awhile and just did not care for it in the end.After the 16# Wolff spring takes a set you do not need the FLGR as the spring will not twist and bind anyway.
Trick I picked up from the 1911 boys is to install the recoil spring and lock the slide back for a couple hours.That will settle the spring down and prevent binding and twisting.
I was told by CZ-USA that installing the FLGR will void the warranty.
If you have problems assembling the 97 with the stubby polymer guide rod,here's another trick.
Install the spring and guide rod,make sure the detent of the guide rod aligns with the notch in the barrel foot.While holding the guide rod and spring in place with your fingers,(holding the slide assembly in your hand with fingers wrapped around)ease the slide onto the frame.Once the guide rod and spring are started into the dust cover of the frame it will retain the spring and guide.Continue with assembly as usual.

I'm partial to FLGR for easier assembly.

And, FWIW, I use 18lb. springs on my CZ75B's and I used a 16lb. spring on my CZ97B. No problems there.
