1) What do you own: I own a stainless GP100 in 4 inch with adj sights.
2) What grips do you use? I think the Hogue Grips are absolutely the best on the market for this gun. They completely cover the backstrap, whereas, the hogue grips for a 686 do not (Sorry for the jab Smitty owners!) It makes a difference with full power loads.
3) What loads do you use? I use a variety for plinking, with winchester 110, 125 being the most common. I also shoot Blazer .357 and Winchester 130 grain .38.
For woods carry I am ether carring Winchester 180 Partition Gold or corbon 200 HC.
4) Any modifications? I have none other than the Hogue grips.
5) What would you like Ruger to do differently to a GP100? Nothing really, I am so pleased with mine. However, i would love to see another run of the Target Grey to match my SP101 2 incher. Maybe even an 8 inch version for hunting. I plan on the purchase of a 6 inch for hunting, but the 8 would be even better! The tigger seems to consistely get better with the new Ruger right out of the box.
6) Holster(s): I carry mine in a cheap but effective Uncle Mikes OWB (As if anything will really fit IWB!)
7) Speed Loader(s): HKS and Bianchi.
