I tried the Mauser version on my Dad's Commercial 98. Wow! I'm impressed! Going to get more 98's as I really like it. Had to grind it a bit as it was a tad long out the firing pin hole but everything fits to a "T". Couldn't be easier to change.
Trying a Remington & a Weatherby next.

Speedlock!

...and what functional improvement did you see...

A much smoother and instant ignition. It wasn't just me, Dad and his friend noticed the differance as well.
