Finally got my new 709 slim out to shoot for the first time on Saturday. After a very thorough cleaning and lube job I loaded up with Tulammo 115g fmj. I have read on here that others had questions about the reliability of the steel casings in this gun. I shot 50 flawless rds with the exception of 1 FTL. I believe this was caused by my inattention to cleaning the magazine spring. Upon inspection of the magazine spring after shooting, I saw the the spring was coated with yellowish/white crud which I proceeded to scrub off. The magazine seems a lil smoother now and I think this will resolve any loading issues. I was completely impressed with the performance of this pistol as was my 14yr old son who fired it flawlessly as well.
