Ok first of all let me say i love my Glock(s). Now that I have said that let me elaborate on my thread title. I have just recently purchased a Glock 22C. "C" meaning compensated. The barrel and slide are ported and while that seemed like a good idea to me I have come upon 1 real problem and 1 theoretical one that I have yet to test. Problem 1- After about 20 rounds I noticed the front sights began to darken. This is from the carbon and what ever other **** comes up out of the ports during shooting. This presents as a problem for me since there is a potential for my needing to operate in a low light setting. The last thing I need is an already difficult to see front site. Sure its bright and white when clean and in my holster,but what happens when.........? Get my drift? Problem 2- I train and practice a technique that some may have read about that D.R. middlebrooks is teaching at the TSA school. This is called a fist fire technique. Without getting into the details of this, the issue of the techniques close guard position would put the weapon in close to my body and the ports damned near under my chin at about the level of the xyphoid process and slightly to the right. Basically under the right eye. The problem that arises from this shooting style is that with a ported weapon, am I going to burn my chin or get **** in my face? Now my job as a TEMO means that the vast majority of the time I will have a balacava on and goggles in place. So perhaps since thew hood is nomex, it's a non-issue; or is it? Some suggest to just buy an after market barrel and forget the whole thing. An ideas? Suggestions? Should I just sell it take the loss and write it off to bad move on my part and get a G22 and call it good?
