I prefer the look of the square back, but are there any issues shooting it, the guard hitting your finger from recoil for instance?
The design of the square back trigger guard was probably made with the question of appearance alone in mind, for it certainly does not does not seem to have any useful or practical value. In fact, it would seem that such a design would be highly impractical because of the chances of the pointed rear of the trigger guard proper becoming fouled in the holster, or pocket, from which it was being drawn. The square back design is attributed to Colonel Talcot of the Ordnance Department of the U.S. Army, who seemed to have a fondness of the symmetry and beauty of the design. Since Colonel Talcot had much to do with the purchase of handguns for U. S. Army - a potential purchase of some size - Sam Colt was certainly one to cater to the whims of those who could help him sell his handguns; so the square back trigger guard it was! The story is that when Colonel Talcot was convicted by a court(s) martial, Colt immediately discontinued his production of the square back design and changed to the small rounded trigger guard.
The Super BlackHawk with the square trigger guard is the only pistol that I have ever sold that I don't want back. Every shot was painful.Squareback trigger guards have been a bone of contention since Colt manufactured the Walker, the 1st/2nd Model Dragoons, the 1848 Pocket, and the 1st/2nd Model 1851 Navies.
Nathan L. Swayze's treatise " '51 Colt Navies" (1967) states on pg. 28-29:
Whether this anecdote by Swayze is correct or not, it is apparent that Colt went with the rounded (variously large and small) trigger guards on both the 3rd and 4th Model 1851 as well as the 3rd Model Dragoon, as well as the 1849 Pocket.
Having said all that, I love the look of the square back TG.
As the OP stated, many folks find it uncomfortable/painful to shoot due to the impact upon the middle and possibly ring fingers on the shooting hand.
I have never found that to be a problem and have owned a Ruger 3-screw Super Blackhawk .44 Mag for years and have never encountered any problems of that sort.
I own Piettas. The upper pistol is the newer (2015 [CN]) G&G based upon their newer grip style with the round TG. The lower pistol is a (2014 [CM]) 1851 Navy with a Pietta RB TG that I ordered from Cabela's but ordered from Taylors the Pietta SB TG from them back then to replace it.
I plan to purchase a new Pietta 1851 Navy with the round TG so all I have to do to create nearly 13 variations is to swap barrel assemblies and cylinders. Piettas (since ~2000) are all CNC machined and therefore those parts all interchange effortlessly.
Just for comparison.
Just for SB TG comparison, I also have this Replica Arms/El Paso Texas 1848 Baby Dragoon .31 with load lever/rammer (date code [XIX] 1963).
Thanks for looking,
Jim

Never really cared for the square back trigger guard design. Always a matter of contention with that blasted trigger guard hitting my middle finger. A friend of mine had a really nice set of oversized grips for his Ruger Super Blackhawk and they worked wonders taming that square back beast. I think I will stick to the round trigger guard design like the one on my Colt 1860 revolver. Much more pleasant to shoot and looks great!
