They are not drilled and tapped. You'd be better off to get a set of the Crimson Trace Laser grips if you can't see the sights clearly anymore. The red lasers ain't worth a damn in bright sunlight, though. The green lasers are more expensive, but worth it IMO.
I'll be ordering a set for my new Model 69 snubby .44 in a few days! Just got my yearly birthday coupon from Midway, yesterday. Haven't had time to shoot mine yet, but I'll post a target when I do.
