Looks good, reminds me of a good home defense gun without the stock.
Yeah I had to do the same things to the hammer and trigger hook on mine, I knew about the hammer and copied the original, but didn't know about the trigger and had to fight to get it apart once I realized it.
If you feel like it later you could get these, they are nice & a decent price
