Employers will typically train you for whatever job you get right out of college.
As a fresh graduate trying to find any kind of employment beyond the 'no college degree required' level for the past year, I got to go with Modus, this ain't happening nowadays, not without a serious helping hand from contacts that you may or may not get the opportunity to make during your time at an undergrad school.
Not to cast assumptions on your age, but I think things were radically different for a fresh physics BS that was flexible many years ago. Today this is not really the case. A BS is the new high school diploma. With the glut of graduates with specific skills that employers have to choose from, it's a buyer's market.
If you are a US citizen with the ability to pass security clearances, it opens the door a little wider to employers that are a lot more physicist-friendly than the typical private corporation. Ie: US navy, army, NASA and DOE internships, defense contractors like Northrop Grumann and Lockheed Martin, Exelis, etc. About 90-95% of the job advertisements I've ever seen in the past year that explicitly wanted BS Physics majors at the starting entry level were from these enterprises. The remainder were microscopy forensics, the occasional financial analyst group in NYC which explicitly only wants Ivy league/top-20 school graduates, and 1 or 2 optics manufacturing firms. Everything else = PhD or a specific MS required.
I recommend having a gander at APS' job statistics for recent physics graduates. They have a US map with a list of employers that have hired physics bachelors straight out of college by state. Mostly, they seemed to be small manufacturing firms and occasionally bigger corps like 3M, Xerox, and OFSOptics. This is a good place to look and find companies to seek out in your region and follow suit, I am doing this right now.

Essentially, without a graduate degree, I strongly doubt anyone who stops his/her physics education at the bachelors level is going to make it into a career-style job.
