I was going to ask the "one or two hand" question myself.

Rhetorical question: Why do most people shoot two hands?
Answer: To conceal poor trigger control.
Poor trigger control is often deeply rooted in the psychological impact caused by the motion of the gun during the hold/aim. You got to learn about and understand the concept of natural arc of movement.
There's lots of exercises to help. Check out targettalk.org.

The M52 is a bullseye gun. The grip angle was chosen as an improvement over the 1911. That's debatable, perhaps, but it certainly is usable.
The trigger began as an adoption of the M39 DA trigger. With the linkage and pivot point, it can be problematic. But, dry fire should help. I'd stay off the 1911 a while and see if you can adapt to the M52. Lots of folks have the opposite problem, finding the 1911 a pain in the butt to get used to.
The weight, or lack thereof, is also a non-issue. Either use the weight or don't. I suggest train/dry fire with the weight.
I suspect that most bullseye shooters using the M52 would use the weight primarily for shot to shot recovery purposes during the rapid - timed fire stages.

Anyhow, just a few thoughts.

Best Regards,
Jim
