I used this in the Costa Ludus class with TSiWRX. I had cleaned/lubed it the night before class and wanted to see what the failure point would be (if any). well unfortunately there were on issues like one would expect, it was quite the opposite with the polymer guns having issues, including an M&P having a slam-fire on day3 (which AETi took a look at an said it was the gunk that was in the frame) and even a Glock had an issue. Out of the 1911/2011's used in class there was only 1 that had an issue, and that was on a 9mm Loaded where the ejector had come loose (SA glues the ejectors in and doesn't use a pin). Her gun still functioned, but she said it didn't feel right.
Anyways, here are the dirty pics after then end of class.













I've also never had an issue with my other 1911's that i've used in classes. The SA is mine and the Citadel (which i think Dan now owns) is one that I gave a once over the day before class. The Citadel only had 100rds through it before it was used in this class. Out of the 5 in this class (2-1911s, 2-Glocks, and XD), the 1911's ran flawlessly. Did I mention that this class was in the cold rain, so the 1911's should have failed and the Glocks shine since all the torture test indicate that they (Glocks) are super reliable, right?



So it's not about an expensive 1911/2011 being reliable, it's a properly setup gun that will be reliable. I also feel that a tighter gun makes it more difficult for dirt/debris to get into the gun to cause malfunctions.
