For the last 3 years I've left my G27 gen3 hidden and out of reach from visiting grandchildren. It has been with a loaded mag inserted and the slide locked back mostly to prevent it from being fired as is if found by them. They are now physically able to rack the slide so it stays in the safe while they visit. It has always cycled and fired without any issues and I would like to keep it in this stored condition. I've not seen this brought up before. Maybe because it shouldn't be done. I've read about the RSA wear being a matter of cycles but never heard of being stored compressed.
