M&Pmeister-

I really hate safeties or decockers that are solely on the left side of the firearm.
Would've preferred one without the safety for that reason, despite their inherent benefit mentioned by you and that one can chamber round and clear weapon with it ON.

In any event, do you use your left hand to manipulate the safety on/off and if so- what finger(s)?

Mine is still in 'jail'.

Thanks.
