I purchased a Rock Island Tactical CS earlier this year. I went to Midway and purchased 3 Metalform officer size .45 ACP magazines. They are the 7 shot mags. Anyhow, all 3 magazines failed to feed the last round. The factory mag performed 100%. So before you flame, really I'm a 1911 newbie, I shouldn't have skimped on the mags. Being a police officer and carrying everytime I walk out the door, I can't say I would trust my life with their mags. I sent them an email asking them to replace the magson Friday. Hopefully they will make it right. Anyone else have problems with their mags?
