The Sendaro is fine, without the stainless barrel. The trigger is heavy, but you don't need a certified gunsmith to adjust it, unless you think that it has four (4) adjustment screws. There are three (3) adjustment screws. Adjusting the trigger is so simple that even a DemocRAT could be trained to do it, given no time constraints.
Do a search for Rem. 700 trigger adjustments and you'll see several threads with links to instructons for adjusting the Rem. 700 trigger.
FWIW, I've adjusted dozens of Rem. 700 triggers, with absolutely no failures of any kind. If I can do it safely, so can you. Remington used to include trigger adjustment instructions with their 700's, but our increasingly-litigious society precludes their doing that now.
