I swap sights around to different guns for the verity ! Sometimes the new home sticks, sometimes they move to the next gun. Who cares, just put at least one together on your own !
I'm using cheap Westhunter one piece bases with quick release on my P35s so I can easily move scopes around. I can remove and replace a scope without much need to adjust the scope. Removal/attachment is flipping two levers on each scope.
