Stock (NOS) spring "solid" (coil bind) length should be 1.375", and compressed spring length with the slide at it's rearmost travel is supposed to be 1.625", which should leave .250" before spring bind occurs on a spring made to original specifications (NOS).
While I'd be confident that the WC spring is going to fit and function just fine, you could easily make a jig to check the coil bind length. Subtract your coil bind length from 1.625" to see how close the spring is to coil bind.

You might want to consider using a buffer if you plan on shooting it a lot. Cheap insurance

Yep, I got a Shok-Buff at the same time I bought the springs. There are pros and cons but I chose to install one to reduce impact. That even gives me .10" more spring compression for my original concern.

You can also ballpark the coil bind dimension by measuring the wire thickness of your new spring with a dial caliper and multipying that dimension by the number of coils. Probably not as accurate as measuring the actual coil bind with a jig made up of a screw, two flat washers and a nut and measuring with a caliper but hey, math can be fun.
The recoil spring blueprints I have specify the coil bind dimension as 1.375" maximum. I forgot to mention that in my previous post. My bad.
Measure the shock buff thickness and add to the coil bind dimension and if the total is less than 1.625", good deal. Math is fun, right?

Update - took the 1911 to the range today with the new WC 17 lb. Recoil spring. The gun shot much better and I pretty much obliterated the bullseye area at 7 yards with three magazines. My only oddity was the shells were ejecting almost straight up and hitting me in the head. But no spring lockup Think I will swap out to 16 lbs. and give it another go.
