Bowen rough country sights?

Getting anxious about my GP that I'm going to be ordering in a few weeks, saw an ad here in the classifieds for a sweet customized GP that had the Bowen RC rear sight. I looked on bowens site and it didn't say, are these a drop in sight? Or do they need to be gunsmith installed?

Drop in. Made to be set in place with loctite once you find the load.

They are simply an awesome sight.

Seriously tough construction with amazingly tight tolerances.

Think I'd prefer the click adjustable target version over set screws.

I have one with the set screws in one of my GP100s. In three years the sight has not moved, in spite of having carried it in a holster, given it a fair share of shakes and hits, and shot a few thousand heavy .357 mag loads. Dead-set accurate and rugged. Once I had it zeroed-in, I put a drop of blue Loctite in each screw.

I installed it myself, and I'm no gunsmith. Fell right in.

Thanks folks, looks like one is in my future.

The rough country's are my favorite sight.When locked down,they are like a solid block of steel.I find that the reduce group size slightly compared to factory,due to the slop in the factory sights.
