what suggestions do you have?

[Lycanthrope]

For concealment the Commander sized gun is fine. Break her in with full metal jacket rounds and run a few hundred through her. Keep the rails lubed.

IMHO, te two most common areas that can cause a malfunction in a 1911 are:

(a) bad magazines/springs.

(b) too much/too little extractor tension.

The 1911 should through empty brass about 6-8' from you. Too little tension and the gun will dribble out brass and occasionally leave one in the chamber. Too much and the gun tosses brass a mile and will occasionally stall a fresh round on the ramp. The good news is that the extractor is easily adjusted.
