I am waiting on a new spring for my hw95. I have an extra spring for my Diana 34 When I laid them beside each other they are close to the same length. My 95 is apart so I tried the 34 spring in it. It would fit inside the piston but is a bit snug compared to the original. My question is would it cause any damage to the guns piston if I used the 34 spring till the proper spring arrives? thanks for replies

My concern would be that during compression the spring bloats up and might do something to the sompression tube. .. What happened to the 95 spring..?

Your 34 Diana spring is about .008 thicker wire than you HW95 spring. You may encouter binding within the piston due to this. Hence rubbing the piston inside and exterior of the spring itself. IMO this would slow your gun down upon its potential. Most round wire springs, under compression expand upon their outside diameter.
Option 1 use the correct spring.
Option 2 polish the piston interior to open up clearances. Moly tar will help upon a friction issue only to a certain point.
Option 3 re read option 1.

It won't hurt the piston but may scratch the piston liner a bit if it's too tight. I'd have to have it in hand to say whether of not I'd do it for curiosity, but if a bit snug you could sand the outer edge of the spring with 600 paper and grease it so it both fits better and less likely to scratch. If it is larger OD then it's no doubt looser on the guide so it may make more noise. Another question would be is it snug because the OD size or because some coils are slightly offset and/or the spring bent? If that's the case, which is normal, then I wouldn't worry at all.
