Gentlemen; I am new to this forum and I have just purchased a new 75D PCR. I also have a 75 Tactical. I love the feel when I hold a CZ in my hand it is a great fit. I purchased this CZ because I feel better with a decocker than a safety as a CCW. I am no longer a young guy and I find that racking guns has become more difficult over the years and I am currently recovering from 2 shoulder replacements in the past 7 months so that isn't helping at this time. I am considering if I need to replace my recoil spring. From what I have seen I believe the new CZ comes with a #16 pound spring and that #11 and #14 may be available. I am looking for comments on replacing the spring if any of you have any experience doing this.
