Cayoot..
I would be happy to post a pic of my gun.. will be tomorrow though, as I am at work. I have nothing against the 41 actually.. I just enjoy harassing the 41 fans who tell me it is more powerful than the 44.. I have a freedom arms model 83 in 41 magnum, which is similar to my blackhawk. I shoot it quite often. It has a bisley type frame on it.. many believe this to be more comfortable to shoot than the colt style frames. In a 41, you should be fine shooting a blackhawk with a set of uncle mike's, pachmyer or hogue grips.
If you are going to shoot a 44, you have to ask yourself if you really want to stick with a single action. I have several guns in 44. I own a .44 Smith and Wesson Mountain gun, a 4 inch model 29 (Purchased before the mountain gun), a super blackhawk with a 4 5/8" barrel, as well as a 12" Taurus M44.
While I am sure there are those who will cough at my next suggestion.. think about this. I have just purchased a stainless steel taurus tracker in .45 colt. I have been loading it within the pressures listed by taurus and it handles the loads beautifully. Taurus now carries a .44 magnum tracker.

Now let's talk about strenth... Taurus states that it is safe with a 240 grain bullet doing 1340fps, they also state it is safe with bullets within SAAMI pressure ranges.

SAAMI pressure for the .44 magnum is 39,000 CUP. The standard loading of a 240 grain in the 1300fps range floats from 36,000 CUP to 38,200 CUP in the hodgdon manual. If you follow the hodgdon manual, you will see there are a number of heavier loads that are in that pressure range. You will have to experiment with bullet length though, I understand the .44 magnum tracker to have a slightly shorter cylinder. I understand this is to keep people from loading extremely heavy bullets into it. But the fact that you are looking at 250's and such, you shouldn't have any issues. I personally love the tried and true Elmer Keith load of 17 grains of # 2400 with the 250 grain Keith bullet #429421, it hits 1,200fps out of my super blackhawk. I am currently eyeing the .44 tracker at my local shop and only money is holding me back. But not for long.

If you enjoy reloading and already have the dies, the .44 has alot of potential. If you think you will want to load full power loads, get a super blackhawk, a redhawk, a freedom arms, or even a taurus raging bull in .44 magnum. If you don't need the extra heavy loads, but enjoy the .44 magnum, get a mountain gun or a tracker. The tracker is stainless steel, ported, and comfortable to shoot. I take the grips off mine and stick it in the dishwasher to clean it. Then lube it and away I go. It will definately stand up to the weather and abuse. Just some ideas..
P.S. As for sights, I have night type sights for my super blackhawk. They were made by Williams before their firesights came out.
