Right on, I think mine are the Meprolights, can't remember. I got them off here some time ago and actually packed them in with one of my couple USP 45's thinking I may convert one with 3-dot white sights to these Mepro adjustables. I got a couple really nice site pushing tools in case I got locked down, I could tear my own stuff up correctly at least!
Shooting:
Yes, +1, for a big ol' plastic gun, they sure shoot dreamy!
Suppressor:
That is what I am reading up on is that for this particular gun, the "Osprey" (and one other I cannot recall right now) is "The-way" to go. Heck, I have like 6 or 7 hosts, probably time to throw a party. Kind of want this buzz to settle down before getting back into suppression market but either way I have some stuff to get done first non-gun related anyways ahead of that spending.
