I want to use my G22 with a TLR2 for home defense. I just read a gun magazine that explained the problem Glock 22 .40's have with Streamlight TLR2 attached. This effected many police departments. I had heard of it before but didnt understand. Malfunctions could be caused by the high velocity of the slide with 40's. The slide moves so fast that it could close before the next round fully feeds up from the magazine causing a malfunction. Would using the 180 gr. result in slide velocity being any slower than with 165's? If so, maybe the 180s would be a better choice. I like speer gold dots.
