I've never liked the SA pull, but I did much enjoy a Wilson Combat tuned model that had a very smooth DAO pull. Couldn't complain about anything else. Biggest problems I had with issued sidearms were bad magazines; easily solved with an order to Midway for some MecGar mags.
Should you be a philatelist, the Beretta action lends itself to suppression without use of a booster. Thompson Machine and DeGroat Tactical make some lightweight direct thread cans that will come in under the 8oz theoretical limit.
