G22 & Harris Bipod:
you can fit a weaver mount one or:
you can open up the forend and fit a QD (may affect your warranty.)

Side mount walther parts are available for QD's on the sides to carry a sling.

I mounted a rear QD as well and use my usual sling and bipod.

The trigger rod can be straightened slightly, or a guide block fitted, or a stronger rod fitted. In all cases check your trigger is still safe!

My zero kept wandering but 2 things fixed it.
a) Fit the metal shim from Walther in the forward scope riser.
b) don't store it in the gun cabinet in the plastic travel case.

To make it better, I'd like a metal interior to the scope rail risers, solidly connected to the action.

Otherwise I love it.
Have it set for left handed eject.
Caution, do not fire it with the opposite hand to what it's set for.
It almost took my mates front teeth out and he was holding back to compensate!!!

Mines likes Winchester subs.
