Do you guys like your M&P's with our without the optional thumb safety?
Without, but I keep and carry mine in a holster. If it was just sitting loose somewhere in a drawer or glove box i might consider the safety.
I do like the magazine safety on mine though, as it's a quick and easy way to disable the gun should you ever need to do that. Some people will advocate no external safeties, but different strokes, I guess.

Thumb safety.... Gurgle, gurgle... Yuck! I just threw up in my mouth
A properly trained individual is not going to forget to take the safety off...
I really want a 9L or 9pro for IPSC.
One needs to be realistic and assess their own needs objectively and make a decision. Once made, become very well trained and familiar with your chosen firearm.
