Here's a recent video from my channel where we are applying Nikyo (a wrist lock found in aikido and kata) from a lapel grab. We are making use of focus mitts and armour to strike before the locks. I find the strikes useful to either distract, spoil posture or unbalance before applying the lock.
We generally layer a drill like this to start slowly with a partner then follow it up with pads then finish it off with a few attempts with protective kit on. Hope you find it of use :-)
