Josip89,
yes, I think it is a good idea. I used to make them for people in Grizz country. I used non-Ruger platforms but I used to make them.
I have a suggestion.. look at the L-frame Smith and Wesson's. First the newest model in 44 SPL/Mag; the new-ish Model 69. it is a 5 shot 44 special/magnum. wonderful gun. you can find them for between $750 and $900 dollars on many websites. You could go for the 29/629 N-frame. Everything the 69 and 686 can have done to it the 29/629 can have done to it. Next you could look at the 686 and 686+ for 38/375 Mag (L-frame as well). the 686 + is a 7 shot 357 Mag with a very easily smoothed out D/A. The reason I know, I am primarily a pistolsmith that does such things. the hammer can be easily bobbed for a no snag look. I would also suggest finding a model 25/625 in 45 Colt where you can put a serious hurt on a bear with juiced up 45 Colt 300/350 grain slugs. Another suggestion is the X-frames, 460 S&W and 500 S&W, both can be better than any other caliber on the market. the 460 can shoot 45 Colt, 454 Cassull, and 460 hand loaded. none of those hand loads can be beat. The 500 might be more of a close up (75 yards to 0 yards) but it can deliver one hell of a punch on bears or other toothy disagreeable things. All adjustable sights will snag; however, there is a less likely snag on the rear sight than the hammer. S&W can be outfitted with a set of night sights for low light and dark encounters. the Tritium filled sights are offered for around $200.00 per set and they are adjustable. there is a cross over sight that fits the adjustable sight screw pattern and cut out with illuminated dots that is virtually no snag as well. They are just not adjustable.
You can do the same exact thing with the new/newer Colt Pythons, Cobras and King Cobras in 38/357. if you can find one of the 1997 through 2008 Anacondas they can be done up the same way as the S&W's This time in 44 SPL/MAG or 45 Colt.
I have tried really hard to smooth out a Sturm/Ruger, but nothing I have ever tried has ever made one lick of good in my opinion. My customers on the other hand loved what I did. They never came out to my satisfaction. I might have dropped the trigger to a reasonable 6 pounds, I might have had success smoothing it out a bit. but nothing like what I can do with the Colts and S&W's.
the last last one I know how to and have smoothed out is the Raging Bull series from Braz-Tech International.. better known as Taurus. these guns have come up in quality over the years, but I am still hesitant to have confidence in them.
My advice is to find something you are comfortable shooting then make it your own. there are some very good quality chest rigs that will accommodate the big framed revolvers. Alien gear, Hunter, and many more make great chest rigs. I happen to have a few from my grizz country days for a few 1911's in 10MM (Delta Elite), 45 Super (Para-Ord), S&W 29 & 25; 44 mag/45 Colt.
I hope this helps with either finding or building your dream bear gun.
