Thank you. I had seen conflicting info between MAC's review (saying he planned to remove it) and a Ruger forum (saying it would not come off).Yes it can. If I remember right the holes can have the filler screws from a scope rail placed in them if need be
Copy that.You can get the 22/45 lite with both rails also
Copy that.
Additional question based on your comment: I know the Mark IV Lite has a polymer lower. What is the Mark IV Tactical lower made of, aluminum?
Regular tactical says aluminum: https://ruger.com/products/markIVTactical/models.html
22/45 tactical says polymer: https://ruger.com/products/markIV2245Tactical/models.html
In summary, if you want a Ruger Mark IV with a threaded barrel, you have three choices:
The lite version...bull barrel vs sleeved barrel.
- Mark IV Tactical - Aluminum Grip Frame - 34.6oz
- Mark IV 22/45 Tactical - Polymer Grip Frame - 33.3oz
- Mark IV 22/45 Lite- Polymer Grip Frame - 25.0oz
Mark IV Target has a stainless frame with threaded bull barrel.
