Walther/Hammerli AP20 - Slimline Cylinder Upgrade

[lyoke2]

I have the basic model of the Walther/Hammerli AP20. I replaced the grip with one of Berryhill's Precision Target Pistol Grips (one the best decisions I have made). But I still have the short grey air cylinder on there.

I did not know if there were benefits to the Walther Slimline Cylinder over the basic model cylinder.

Thank you!

I'm not sure how the volumes compare. The big advantage is the built in gauge, so you never have to worry about how much air you have.

I believe the volume of the cylinder is higher too judging by the extra shots the Pro version has over the standard and really only the grip and tank are different.
