I had a Swampfox Liberty with Ironside shield and plastic RMR plate, the suppressor sights would barely cowitness due to the height of the Liberty. After six rounds of 10mm Underwood 220gr Hardcast the posts on the Zev plate and the screws that mounted the Liberty sheered off.
I have two 407c's and a 509t, of which one could be mounted with a steel or aluminum plate, but again I would have the cowitness problem.
The SCS mounts directly to the slide eliminating the plate, which would rectify the cowitness and hopfully the problem of sheering the screws.
The SCS appears to have smaller sight picture than any of the above mentioned sights, I concerned that the suppressor sights might take up to much of the sight picture. Just looking for a good combination. The Underwoods hit hard, and I would like to continue using them. Did I mention that they hit hard
If knowone else has had any experience with the above combination. I'll give Holosun a call.
Alchase, Thank You for the response.
