I did not intend to cause grief in this thread, but I am a gamer, because it is a game. Most of the people commenting are my friends and I know there is no hurtful intent.
I will almost always opt for a slide lock reload if given a choice. There are too many steps in a RWR, and this leads to it not being as reliable as a slide lock reload. Also, if you are reloading while moving behind cover, then you are not moving as fast or hitting your mark at the edge of cover as precisely. This can often lead to a COVER call, ask me how I know.
If you are properly using cover, you don't need to move to do your reload, so you are indexed on the target when your reload is complete. If you keep the gun up in front of your face, then you minimize the time needed to reaquire your sight picture.
Most everyone in your division will be doing the same thing, so know your strengths and depend on those strengths.
I hope you find the correct answer for you.
