Being an onery old curmudgeon, I wouldn't use something in a "Practical" match I wouldn't use in the real world.
The amtch guns have gone the way of IPSC, with a standard gun not competitive any more.
The LE 3 gun matches I used to compete in used duty equipment, for me that was a Model 64 revolver in 38 Special, an 870, and a Mini 14. Mods were extremely limited.
That kept the playing field level and had more pertinence for training.
