sv45 Posted September 3, 2018 What recoil spring rates are needed for 2011 sight block guns? Is there any difference to a standard 5” gun. The reason I ask is I’m having one built and I handled one at the range and the owner said he runs a seven pound spring in a .40 Caliber. That seems really light.

jcc7x7 Posted September 3, 2018 (edited) 8 or 9 lbs Wolff variable in my 40 ( using a 40 TruBor blank unported, which make the bbl 61/4 ") All my other 40's without the bbl weight/sight block I run 11-13lbs springs in.

Novagunner Posted October 3, 2018 I’m running an 8# in my 5” Limcat perfect sight. Runs great and super flat. Quote Share this post Link to post Share on other sites
